haha
i did enjoy the small 'Boom' at the end there
the OP? original poster at a guess?!
that was very similar to my advice when i messaged him
- get basic upper body strength up to a standard (enough to control your own body weight)
- core work for balance and allround stability
- riding and basic unweighted step jumps (if you do decide to include a plyometric specific session as they can do in 10mins what an hour of riding can do)
all very complex talking about muscle fibres and wont apply to many just yet...i am still genuinely interested about the most efficient body strength/weight/speed ratio (coupled with gear ratio) for trials.....and how much of the jump is down to the quick turn of the wheel and how much is down to the body jumping/pulling up
id be curious to see sprint track cyclists try trials with their explosive speed and power?! 3 squats of 250kg...that would be some acceleration on the rear wheel! or alternatively trials highjumper who can clear 2.40m :/ hmmm
just read britains leading female bmxer can squat 150kg! not bad compared to the likes of TRA

From what i've learned, training for more strength increases fast twitch muscle fibres and it is fast twitch muscle that is mostly used for trials. You seem to be pushing the idea that if you train for strength you'll be slower, which just isn't true.
im not pushing the idea that you'll be slower, ive never said that...im just saying it doesnt necessarily always make you faster?
for the fast twitch fibres trials riders use (type 2b if we are getting fancy) - to quote sportsmedicine.com
"Type IIb Fibers
These fast twitch fibers use anaerobic metabolism to create energy and are the "classic" fast twitch muscle fibers that excel at producing quick, powerful bursts of speed. This muscle fiber has the highest rate of contraction (rapid firing) of all the muscle fiber types"
some studies show that the typeIIa fibres (sometimes known as intermediate fast twitch fibres) can produce the same force (as IIb) whilst dealing with low velocity movement...studies of how to focus on IIb over IIa are still inconclusive but suggest putting the muscle through alot of force at high velocity. As a result, theories suggest that slower very high weights stimulate the IIa's more so as the body has a natural drive to be as efficient as possible
to quote bodybuilding.com (top site on google after typing in "best way to increase fast twitch fibres"):
http://www.bodybuilding.com/fun/kelly15.htm
Exercises That Increase IIB Expression
These include:
Plyometrics utilizing loads, plyometrics, "drop and catch movements", jump squats, olympic lifts, drop jumps, depth jumps, speed squats, speed benches, reactive squats, as well as most ballistic type activities in which either high speeds, and or supramaximal forces are employed.
The force from a "drop and catch" type movement utilizing loads, or a plyometric type movement, exceeds that which is created with weight training. More importantly, the velocity component and the speed that force must be created is much greater.
Put into practice one could start from the top and perform a quick "drop and explode" in a chinup, dip, squat, or olympic lifting movement.
The force created at the reversal from eccentric to concentric is great and must be applied extremely quickly or progress will not occur.
This is just a brief section of what is a large section going into much more detail about typeIIb fast twitch fibre growth stimulation. it includes links to scientific papers and research which have gone into depth about how training effect these. one of these:
Adaptation to chronic eccentric exercise in humans: the influence of contraction velocity (http://www.ncbi.nlm.nih.gov/pubmed/11606016?dopt=Abstract) proves interesting reading too stating,
"The percentage of type I fibres in the FAST group decreased from [53.8 (6.6)% to 39.1 (4.4)%] while type IIb fibre percentage increased from [5.8 (1.9)% to 12.9 (3.3)%; P < 0.05]. In contrast, the SLOW group did not experience significant changes in muscle fibre type or muscle torque. We conclude that neuromuscular adaptations to eccentric training stimuli may be influenced by differences in the ability to cope with chronic exposure to relatively fast and slow eccentric contraction velocities"
its not an exact yes/no answer...there are theories and no doubt countless studies ongoing to work out just what we are talking about. it doesnt detract from the fact that plyometrics is often the main focus in ths
-
Also, some of the things you've said regarding muscle types and training don't seem to correlate with what i've learned. If you could back up your points with relevant information that'd be cool.
ok, fair enough, apologies...my initial post was harsh, i still feel it wasnt worthy of being sticky'd and wasnt hugely clear in how it was written. im ok to disagree with some of the pointers (most plyometric training done on the bike/power lifting being the most effective way to increase fast twitch muscle fibres i.e. the 2-3 reps) thats my opinion on it.
that comes mainly from experience in what ive seen and done, not 'formal' education. i dont think ive gone into much formal theory about muscle types and the best way to train them? briefly skimming over what ive written i cant see where i recommended any other training other than core and plyometric (which is perfect for explosive power?) if i missed a section then fair enough...its been a long day at work
also...i only used an example of a few guys i know who do alot of the low rep/high weight exercises as evidence that its not necessarily the best way to build explosive fast muscles....the relevant information there being that with their extensive work in that area, they are considerably slower than someone like myself who does very little of that type
not looking to argue, im only hear to help too. again i'll finish on the notion that i feel plyometric (high jump style) training i feel would be most beneficial to trials riders

Just started with the paint stripper. Massive fail! Barely having an effect on the powder coat and I'm using the old formula nitromors. Cannot be bothered with this shit. Powder coat they've used is as tough as the frame it's self I reckon. Gonna have to strip it all round the main gusset at least so I can be sure to cut that out straight. Then it looks like I'll have to get it shot blasted and might as well get a proffessional clear coat while it's there, instead of the rattle can job it was going to get. So much for doin it on the cheap eh.
defiantely the stuff with the dichloromethane!? wow...3lbs of frame and 3lbs of paint im thinking
-
I basically looked at Gilles when at ucis and noted where he seems to have muscle and not...
i was thinking eactly the same thing when watching the recent video laurence recently requested:
to me anyway, they seem to be pretty slender for what of a better word?! definately not a 'muscular' build in my opinion, though they are obviously unbelievably strong for thier size (reminds me again of top climbers)
almost like highjumpers physique with stronger upper halfs...that is just looking at 3/4 guys but it was what stood out, and the size of the stuff they were doing (with seeming ease) was incredible
-
stoozie has been a gent and kindly offered a swap for the one lever he has, going to hunt round and hopefully find a second set...
failing that, i'll obviously be more than happy with the bike as it is
dont think its work the money/hassle of buying a v2 full brake, swapping the bits and trying to re-sell!cheers for the input though guys

Well i'm thinking as the black bodied hopes with green extras are available commercially now, they shouldn't be too hard to get hold of. I'd imagine tarty could possibly order in the spares you need, or i'd at least try and contact Hope and see if they'd sell you the required parts directly. They've always been more than helpful with me for any requests so I can't see why they wouldn't ship you out the dials and bore caps if you asked. Can't imagine it being too expensive either.
Are the brakes custom Inspired ones, like with logos on the reservoir caps? Bet you can't wait for Tuesday.
hope said the brakes are available to buy commercially, but im not sure if its the trials caliper that comes with them...contacted hope and they said that my only option was to buy them, they cant sell the dials seperately
the brakes are just the black bodied ones...no inspired specific details
shame, the little details of the dials would have been a realy nice finish! will keep a look out...genuinely cant wait, works night out inbetween too so the time should fly by!

Sand blasting can set up stress risers that can lead to fatigue due to fatigue.
Just thought I would throw that in there.
didnt know this, glad i went down the route i did...the guy who did it would only have used it very lightly im sure, not in a way that could cause damage
-
pretty good year, would say 8/10
good
- about a month off now being fully qualified at work
- fitness is better than ever
- video out and new bike!
- social life has been as good as i can wish for
- feeling much more settled with myself
- january's gf is still going strong
bad
- januarys gf! took alot of effort and not great times to get to this comfortable stage
- mum still suffering, but thats due to be fixed early '12
- flat situation has got very uncomfortable, beyond fixing and will no doubt require a move (could be a good thing)
- ankle is playing up a little and im starting to feel old (27 in feb!)
all in all i cant complain at all, very lucky to be in this situation and ive no intention on taking that for granted...expecting an amazing 2012, everything is due to come together then!
-
I think it's safe to say it's time to move on. I know of FANS frames that have been repaired and kept going for quite a while but that was just one crack, having 3 at one time sounds like it's about fooked.
this!
maybe if you cant get it done for relatively little?....but start saving/looking around for something new
*edit, just read the update...just ride it till it breaks, sounds like youre fighting a loosing battle with it!
till then...maybe ease off any big stuff, and enjoy learning some moves without caring if youre going to dent/scratch the frame
-
Would of been miles easyier if you found somewhere to sand blast it, does look good raw but I also like the sound of green as I love the green team.
plenty of places were willing to sandblast it (pre powdercoating it was lightly sandblasted to give a good base to paint and get all the tiny bits left in hard to reach areas)....with the paint being so thick, i prefered to do it myself with chemicals i knew wouldnt damage the frame
love the hope team green too....if anyone reading this knows anyone with the special edition hope tech levers with the green dials (they come with green bore caps too), id be willing to do what i can to swap my silver dials for them! (+ a cash incentive of course:))
-
frame and forks are finally done!!!
so excited, had to arrange delivery for tuesday with work etc till them.....soon as i get the headset/BB faced it'll be up and running
:D -
you need to clamp the hose and 'gently' use a hammer to get it in (its a barbed fitting like a regular magura right?). tarty sell the clamping blocks that have grooves in so not to damage your hose...you may need to improvise

snip
...the big guy in the pic was merely to proove a point that the building muscle - lower rep / high weight training doesnt necessarily lead to faster/explosive musclesdidnt ever claim that what they do helps trials riders, only that all of the extensive knowledge these guys have does help me have an idea of how to train...for most of us, its your basic gym training training that would be beneficial in the early stages - good upper body strength is certainly going to be more beneficial to being weaker, and doesnt necessarily need to lead to massive muscle gain (climbers stand out in my experience for being insanely strong in a very small frame)
when you can physically hold your own (so to speak), to take it to the next level, i highly suspect that focusing on explosive strength would proove most beneficial
i completely agree about trials being under developed
....in the top levels, not enough people take part for there to be a need to stand out amazingly in a physical way. in other more popular 'skilled' sports, its that physical edge that can often set you apart from the resttrials is obviously a massively technical and skilled sport...no denying that. massive amounts of natural talent is needed. the gains in your sidehop height (for example) will improve alot quicker initially with improving your skill than they will improving your strength.
as your level of skill gets close to peaking, (say, like 95% or so of your potential - the sidehop is technically fantastic)...the extra 1% or 2% in skill level will only up your sidehop heights by very little and will take alot longer to achieve - the only way to gain signifigant amounts again more would be to increase the power in the move....ie, increase strength (in the right way)
like yourself, i am very curious to see quite what turns out to be the optimum physique for trials...would be very interested to see how your static moves improve if say you added 10 - 20% onto your vertical jump height...if you do decide, please keep us posted!
there will technically be a way to work this all out mathematically...
would first need to know how much the pedal kick(turn of the wheel) contributes to the distance/height of whatever move...and then how much the upwards/sideways jump of the rider contributes...this slow motion video of ryan leech demonstrates both rather nicely i think:
to get the wheel accelerate to as fast a speed as possible, every person would have thier own individual optimum gear ratio and crank arm length depending on how much power they can generate, and how quickly they can apply it (you want a bruce lee 1 inch punch, but in your leg if you get me?!)
there would then be an opitimum balance between your level of strength, and how easy it is to lug around an 8 - 12kg bike...upper body wise, after a certain level of strength, the level of ease to throw it around wont increase much, and the gain in mass of muscle will become counter productive

The thing that amazes me is people like Chris and Sam who haven't even been able to ride their setups yet. That'd kill me!
think i have trawled this forum and watched more trials vids this last few weeks more than the last 2 years combined! keeps me half sane, edinburgh isnt very riding friendly weather wise just now so thats helped a little...genuinely cant wait till its back
looking foward to hear sams review...was interested to read the guy on OTN talk about it being so easy to manual ("just need to lean back", "no pedalling as usual" - compared to his previous inspired's
) not sure if he meant usually he does have to pedal, or usually he doesntcurious to see what mark means too about being over rather than in the bike, and how that relates to 'trialsy' type moves!
do you know if danny is sticking to the 70x25 btw? or if it was just to see for a while

Ryan Leeches - 'Mastering the art of trials' on youtube
those two will give you more info than any one reply on here!! will be what the majority of the forum will recommend too
-
really enjoyed the vid, though im with everyone else...does look a tad strange on that frame! is that more of a 'trials' orientated frame by TMS? compared to the likes of the streetier 'combo' they do...
-
old school z1 bam`s. quite possibly the best suspension fork ever made. gotta be orange with cnc brace plate (bam- bomber aerospace material)
that brings back memories too...they were nice, but the paces with xtr calipers will look amazing and remind me a little of the forks i used to want but couldnt afford (being 13/14 at the time).... going to hunt round for them when i sort it out
-
thanks guys just woundering because some guys charging me £80 for a pair is this good do you think
how did you manage to register here?! the thought processes involved are much more complex
you have access to the internet, type the brand/model of the pedal into google and find the price of it brand new. depending on the condition, you can judge how good value for money they are
unless this is a piss take, which im thinking it could be
-
green forks and green frame yes... keep that skye style with it
update - has been sent away, its been in the workshop for 2weeks and as expected, its taking a while for the guy to get round to doing it - can imagine with this time of you it may be busier than usual!
so im sitting here twiddling thumbs and waiting!
-
couple of questions - read on OTN there are only 20 full bikes being sold?! surely they made more...?!
also - has anyone else here got one and able to post a little review of how it felt for them?! really interested how the run of the mill rider finds it compared to the fourplay/past frames theyve ridden
gettings massively itchy feet with mine being away for so long, cant wait much longer!
-
(small bolts to strip for an example).
surely with a fixed clamp, the small bolts will only need to be as tight as your regular disc brake caliper bolts? nowhere near as tight as a magura set up, with bolts not needing to clamp anything with as much force...
maybe im seeing this wrong...
a closed system and a method of angling the slaves up/down and i think they are onto a winner...
as far as i see it, if the pad adjustment for getting the pads closer/further from the rim is as simple as a few turns, an open system just isnt needed
could involve the slave having a locking pivoting system, or even something as simple as effectively an angled washer to place underneath the clamp? must be solutions to those problems
-
Yes, I had my forks done by a guy who did a frame for Adam at Tartybikes. Will find the link for the pics, hold on!
EDIT: here
thats very very nice!! that would be a bike to keep hold of, custom black hopes too... did it really save that much on weight?
-
was very tempted when chosing to go down the anodising route...anyone know of anyones frame where they did a custom anodised job? would be very interested to see!
again +1 for powder coating (from a decent company - everything my borneo said)

looking alot more comfortable...did that stuff with ease!
i am pretty jealous of having a place like that to ride during winter
