was awesome. nice to see things slowed down that much. now one of gilles or vincent would be epic. or benito actually

im looking at these too, but i have a heavy old trial tech bb ~350g i would have thought, and abit skeptical about stiffness/weight/strength of these. they both seam well made but ive not really heard of anyone having problems with them, but im out of the loop abit nowadays

ive been this way for a while too. want a streety shit brake for manuals and things but want perfect power, hold and bite on a brake for trials. i have been using heatsink yellows on a smooth rim, just regular cleaning on the rim makes it work much better if you ride dusty areas. much better for the attributes given for traditional trials. whereas on my other bike (tgs/weight) with cousts in plastic backings and a harsh grind.would be overkill for a 24" i think. but something like the heatsink yellows would probably be alright. so i think i will be going for a grind on the rear soon. cheers, ash

looks like they were bought abit shit, and 4 months down the line it is still not good. speak to the retailer (tarty?) as you didn't complain straight away i doubt you will get much, maybe some discount off the next order if you are lucky. but if they had turned up to my house in that state i would have sent them back

cheers for the info guys, i do need new tyres, and was looking for these. how annoying! holyrollers it is i think the new sky looks mint, extremely pleased to not see it in gloss!

agreed wont work. would also feel pretty horrible if it did work

IDGI

this should win! was awesome!

Surely it doesn't count unless it is to concrete?

do we atleast agree that recycling is a good thing?

Can we make a list of do's and don'ts? e.g. Do - Recycle Don't - burn petrol for fun something like this, concise. Not an essay (ben LOL), too much information is often worse than not enough.

thats what she said

Front. Limey Echo TR lever, Magura cylinders, Coust (plastic) pads Water Bleed Rear Echo Original "dengura" lever Magura cylinders, Coust (plastic) pads Water Bleed Best setup I have used in a very long time, people think the echo levers leak, it is the cylinders that leak, all my levers have been perfect. only thing I hate is having a noisy front brake. on my marino I have front TR disc, and TR rim on rear with heatsink yellows on a smooth rim. good in dry weather. The rear TR brake does leak when bled with water, from the calipers (again), so just bleed with oil and it is fine.

LOL at urban dictionary and Cleep Cleep 20 up, 14 down Extension of fisting; tugging of the internal organs through the anus in order to stimulate, or execute. Look what you did. You cleeped your mother and now she is DEAD. not too grim eh? on the plus side, the frame does look like it has been well thought out, im still not set on the pressfit bb though. seen alot of these f**k up on bb30 systems, idiots flaring frames, bearings becoming notchy very quickly etc. Hope this all works out though cheers, ash

lol at his shoes in the 1st post, i had a pair of those years ago!

YOU HEARD!

Yep, pretty much

I agree with everything here, but you should also be looking at the minimum loadings and such that it states in the MTB regulations, they will give you a rough guide of how strong the frame has to be at a minimum. You have to consider the loadings involved with trials and the direction of the forces on a frame for each move, like how much twisting the frame will have under hard loading to the pedals for instance. I also agree that fatigue needs reasonable consideration, there is high and low cycle fatigue, both affect different materials in different ways. For good materials analysis you can find a program called CES on download and it is a massive database of every material and its properties, so direct comparisons can be made. I found this very difficult to get these loading from recorded data, but accelerometers are probably the way to go. and strain gauges For an excellent guide to really understanding the science of cycling keep a look out for the book Bicycling Science, it is a bit out of date, but the principles are there. . Also, my advice, make the prototype weaker this will give you minimum loadings to yield when you want to stress test the frame till destruction. Then you can be confident that the final one you produce for yourself to ride should support you. Then you can try and loose some weight once you have looked at all these things and taken everything into consideration and fancy maybe making another frame, should be much easier. Hope I helped.

super pro is 16 or 18 tooth, once titanium with built in cogs, now steel, the one you are showing is the pro trials, the older ones are fat as f**k and i believe the newer ones are slightly fatter too. they were typically used for 22tooth cogs, but 20 tooth would work. clive leeson did machine several down to 20 tooth only, but they have no anodising on them. which makes me think that mr middleburn went through several variants of the pro trials bashring. although now looking at your pic, it does look like it has been turned down slightly

I think it depends on how far you can hook your front wheel over, I know i usually dont need mine

this was a very weird topic to read at work earlier as it wouldnt let me see the video. but yeah, lean over handlebars, push down, as soon as you feel the tyre at its most compressed, explode upwards. can be hanging on a rock or up a vert wall like in the video, will work for both. back brake off helps with the take off. but use it for your landing! ive always called this a wheel transfer or a wheel switch because you rear wheel replaces your front wheels position. nick manning is awesome at these, got to a point where he was doing it up near 40" walls with his bars at 90 degrees crazy bugger

God would not be pleased with the puns in this thread, surprised he hasnt sent down his arcangle to relieve you from your sin and then murder your children whilst they sleep in their cot

There are adapters that allow you to run gears with horizontal dropouts. Like the old revell ones

ive been very pleased with mine, one of his original material ones, been hammered for nearly 3 years now!

I remember a time when James porter was running 18:17 when everyone else was running 18:15 but it didn't affect him so I was reluctant to go heavier seeing what he could do. But now I'll only be going to change when I swap my front cog as it's a 16. And chains tend to snap with smaller cogs so im wary of that. Then I will have the decision of 18:14 as that is next ratio to trial Cheers ash
