    1090mm 20" Mod

    1. The guy is 6' so I wouldn't say he was short. 2. If you can ride a 1080 or a 1100 26" you can ride his mod 3. Of course it's long because every other mod on the market is for midgets! 1030mm mods aren't long their short!

    1090mm 20" Mod

    Mr. Long Mod reduced the frame to 1060mm and then filmed this: http://www.youtube.com/watch?v=91ypyGRXjk0 He is still running a regular mod stem (150mm) and says the bike is da bomb! Some Spainish pros tested it out and aside from the frame's weight (~3kg) they liked the geo. So with some luck some company will soon start pumping out real "long mods".

    1090mm 20" Mod

    Well I haven't got a video just yet but here are some photos of Mr. Longass Mod in action.
  8. Well someone finally did what I've been going on about for ages. Someone actually made a long mod. No not a "long" mod like the new Koxx 1030mm 20" XTP I mean long! WB: 1090mm BBD: +45mm CS: 340-355mm Now to be fair I never suggested a 1090mm mod as that is probably TOO long but I had talked about 1040-1070mm with 350mm CS. Still this friend of mine decided to boldly go where no one has gone before and I for one am happy he did. I haven't ridden the bike yet but from what he's told me it gaps and sidehops like a motherf...ker! later
  9. That's the best looking Monty ever but then that's easy cause the rest have always been butt ulgy! haha. Still I love small seat tubes so i think this bike looks awesome it would look better without the bump/hump but still very nice! Wonder if the geometry is any good though (monty kinda suck in that department...) Well there is hope cause Mr. Belay was involved!
  10. Hot! but would be hotter if that was the 26" model!
  11. Ok let me clear up a few things. What matters is not only how much the rider is stretched out on the bike but his/her position over it. This is because you can have the same stretched out position with two different top tube lengths if the stem length is adjusted (like in mods). So there is a big difference between running a long stem on a short bike (short in the Effective top tube sense) and a long bike with a short/medium stem even if the overall cockpit length is the same! In the first example the rider will have more weight on the front wheel whereas in the second eg the rider will be in the middle of the bike. Increasing the headangle (eg from 71º to 73º) will also put the rider more over the front end. Increasing the bb drop also shortens the Effective Top Tube but puts more weight on the front end (if you don't increase the rise of your stem). So a the Koxx Derangboy with a +80mm bb drop and a wheelbase of 1085mm has a shorter (ETT) than an Koxx Coustellier 1085mm with a 0mm bb drop. Now assuming all things are equal (chainstay length, bb drop, headangle, stem length) then a longer wheelbase (eg 1100mm) bike will be longer in the cockpit than a short (1060mm) one. I have a 1100mm Koxx and I'm 180cm and I think the bike is too long. Kenny Belay is ~179cm and his koxx was a 1080mm. My opinion is that a bike with a wheelbase over 1080mm is for riders over 180cm. Sure there are exceptions but I think this is a good generalization. If you used to sub 1060mm then going to 1060mm maybe better than 1080mm. I would definitely stay away from 1100 if I were you! Of course if you have the opportunity to try out some bikes then that would be the best way for you to find out how long is enough. The attachment below may help you "see" what I'm on about: Stock_Geometry.doc
  12. Get some Kris Holms instead! Their cheaper and apparently stronger! http://www.unicycle.uk.com/shop/shopdispla...p?catalogid=883

    New Frame

    Geometry wise the Gu Typhoon Short and Adamant A3 short are virtually identical: HA CS Wheelbase BBHeight BB Drop Effective Top Tube Front Center GU Typhoon 72º 362 1000 315 55 562 644.6 Adamant A3 72º 362 1005 315 55 567 649.5 So I'd make the choice on looks, etc. Personally I prefer the look of the Typhoon but you're the one with the money...
  14. I've had a Arrow Prime Bite 24x2.75 both in normal casing (~1000g) and the DH casing (~1300g). I know exactly how much of a b*tch it is to remove the DH one!!! The problem with these tyres is that they are super low i.e. they have very little height. They are basically XC like tyres with huge side knobs to get their 66mm (2.6) width. So they are crap for trials. I'm talking ofcourse about the 24" cause I've seen some of the 26" and they seem to be taller. As for buying them here in Europe I dunno about nowadays but back in the late 90s when I ordered them I got them direct from the arrowracing website. I also got one of the last Mavic Xy 24" rims (which I still use as a front rim) and a free T shirt (which I still use). And I have got a Maxxis Highroller 24x2.5 and on my 38mm I still feel flex on it! But yeah 47mm maybe sufficient...

    Bikecad

    Tis a pretty sweet site indeed been going there for many a year: These were the result of my last play on it: a longwheelbase mod a short chainstay 26" and my future bike another long wheelbase 24" wheeler
  16. My 24" wheeled Koxx 1100 runs at 10.9kg (~24lb) for natural and at 11.4kg (25.1lb) for street. The difference is due to the change in rear tyre. Used to have a 9.5kg (20.9lb) trials bike once upon a time... PS: But if you think about it an 8.5kg mod isn't that light cause the frame still weighs 1.8-2.1kg and the rear tyre is +1000g! Imagine if people started coming out with 1-1.5kg frames that would open the possibility of sub 8kg mods and sub 9kg stocks. And don't tell me they'd break cause if its done right it'll hold just fine!
  17. I saw giant mod bike and came rushing but then I realized you meant Giant the brand and not giant as in size! Still it looks nice in blue though geometry is not earth shattering and thus doesn't tweak my interest! The stock is pretty but again nothing new there.
  18. Ok first off if I were to run a 24x65mm rim on my Koxx Levelboss 1100 frame then there would be no problem in fitting it in the chainstays. Cause remember the chainstays get WIDER the FURTHER away from BB you get not NARROWER (BB is 68mm and rear hub is 135mm). Now would running a heavier tyre solve my problem? Yes but no but yes but no... Err I am using a Kenda 2.5 Nevegal which is 1150g it is already beefy not as stiff as say those silly mod tyres (19"x2.6 1100g) but as stiff as say a highroller 26x2.5. With this tyre on my 38mm rim i still feel some tyre flex which is why i want a wider rim. Perhaps all I really need is a 24x47mm rim (Kris holms) but I find the ideia of going 65mm very appealing (-the cost). As for going stiffer than the normal DH tyre well I don't think you have much choice say apart from Intense but they only make a 24x3.0 which i find TOO heavy. Nokian Gazzaloddi though taller and slighly heavier (the 2.6) are don't have a stiffer casing than the kenda. I have had one and I find the rubber durometer to be too hard. The Nokian 3.0 is better (super cushy like a mod rear tyre) but too heavy. Then there also the fact that I think a 1100g tyre is too heavy for natural anyways (what I mainly do)! So for natural i run a 600g tyre which of course flexs even more than the Kenda! So its either cough up the money and go 65mm and after drilling still add a few hundread grams to the bike or go 47mm save some dough and forget that i could have gone 65mm I think the money is what is going to decide this in the end or my lack of it! haha
  19. Awesome!!! Some else thinking outside the box! That looks so bitchin! Make me what to get my doublewide laced up so i can run it on the front! haha

    19" Tyres

    Thank god for http://www.tartybikes.co.uk/ Mod tyre weights Rear -Tryall 19x2.5 1113g -Monty Eagle Claw 19x2.6 (66mm) ~1100g -Maxxis CC 19x2.5 (63.5mm) 1042g -Echo 1143g Front -Echo 735g -Maxxis CC 688g -Tryall 561g BMX -Maxxis Holy Roller 2.2 575g (wire) 510g 1.95 -Maxxis Maxx Daddy (wire) 2.0 540g 1.85 480g (i used to run this on my mod its actually closer to 2.0 whereas the 2.0 is closer to 2.2) -Tioga Comp X Pro 470g 2.1 (with slow rebound rubber) -Tioga Factory MX 2.1 530g -Tioga Comp 3 2.125 460g (now with slow rebound rubber) 26" Front 400-1000g depending on size Rear Maxxis Minion 2.5" = 1248g dual ply Hutchinson 26x2.5= 1350g (all their downhill tyres) So yeah the currently available mod tyres are stupidly heavy relative to their size and that includes front 20" tyres as well. You can however run a light bmx tyre instead (though they tend to have harder durometers and thus less grip). My rear 2.5 Kenda tyre, which I find too heavy for natural, is on par with most mod rear tyres and its 24"!!! My 600g Specialized 2.5 (my natural tyre) in comparison is on par with mod front tyres!!! (its shit for street cause it pinchflat's so easily) And yet another imperfection in the system is established...kind of like street BMXer running tyres at 100psi so they don't pinchflat instead of just beefing up their sidewalls...i.e. learning something from the MTB DH crowd. What tyres do you 26" guys n gals (if any are present) use? Are you all on those super heavy ~1300g 26x2.5 double ply tyres or are some of you running sub 1000g tyres?
  21. WOW! That looks SWEET!!! And yeah I do run 24" wheels but I have them on a "proper" trials bike (currently a Levelboss 1100) cause I do Natural mostly. I do get tyre sidewall flex at 15psi on my Kenda Nevagal 24x2.5 and on my Specialized 24x2.5 with my current 38mm rear rim. So I want a wider rim! Maybe 47mm will be enough though if I can go 65mm I find myself asking "What's stopping me?" and the ONLY answer at the moment is CAUSE IT COSTS A FORTUNE!!! LOL I get why most of you don't want a 65mm rear but I ain't most folks...cuz I'm crazy...haha So with all those holes you managed to go from 1150 to 900g umm I think I can go under 800g for the 24" then cause I still see plenty of space to drill (smaller holes though). Well I still have to think about whether to cough up that much money or go for the Kris Holms 47mm... Anyone got a pic of the rim with a tyre? Anyone got a pic of the rim with a tyre on a bike? Anyone got a pic of the rim with a tyre on a bike doing a trials move? PS: Thanks for the pic!

    19" Tyres

    Ok then maybe I need to explain before anyone is willing to share their precious info (mod tyre weights) I'm a tech geek which means I love to think about how different variables effect bikes eg geometry, wide rims vs narrow rim, round profile vs square profile tyre, etc. I like to compare parts, compare weights, rubber durometers, yada yada. For example: 26" rims weigh more than 20" rims because there is more metal on them...duh right? (assuming same width and brand and model) eg: Alex DX32 rim 26"-765g 24"-650g 20"-540g 19"-510g The same should be true for tyres, right? The average rear 26" 2.5 tyre used by trials riders weighs what? About 1000g-1300g. How much does the average mod rear tyre weigh? (That's my question to you) The only figure I have is for the Maxxis Creepy Crawler which is 975-1050g. So that seems to mean that mod and 26" tyres weigh just about the same even though they're way different in size! Lets look at it in another way: A Kenda Nevegal wire bead double ply (downhill version) Stick E 26x2.5 tyre weighs ~1350g the 24" version weighs 1150g (i have one). Thats -200g off the 26" version. Or to put it another way the 24" tyre weighs 14.8% less than the 26" tyre. So if we use this to calculate what a theoretical 19"x2.5 Nevagal tyre would weigh we get ~773g (using the 14.8% decrease for every 2" decrease in diameter ) 650g (assuming a 200g decrease for every 2" decrease in diameter) Ok so 650-773g is what it should weigh and the maxxis tyre weighs ~1000g. Still ~230-350g difference there. Well mod tyres are TALLER than 26" tyres so ok they should weigh more than you'd first expect. Fair enough so perhaps 750-873g would be a better figure but that's still 100-300g less than than the Maxxis tyre!!! Lets use the Maxxis Highroller instead: Highroller 26x2.5 wire double ply 60a durometer=1250g (according to website) Highroller 24x2.5 wire double ply 60a durometer=1150g (according to website and comfirmed by my scales) Here the difference is only 100g, half of the Kenda. Again if we use this to calculate what a 19"x2.5 theoretical Highroller would weigh we get: 934g (using %) 550g (using grams) Ok so here the figures approach the Maxxis CC weight of 975-1050g. And let us not forget the tyre height thing so weights would be 650-1000g. Better right? But I'm talking about heavy DH tyres and not tyres like the Michelin Hot S 2.5 which weighs 850g!!! If they made a mod version it'd be way lighter maybe as low as 500g!!! The Maxxis CC is a lightish mod tyre isn't it? I've weighed a low end Monty Mod tyre from the mid 90s and it weighed 1300g!!! And why is this so? Because mod tyres have super beefy sidewalls!!! Why don't they make 500-800g mod tyres? ------------------------------------------------------------------------------------------------------------------------------------------- Now the above is merely an idea of mine that I'd like to confirm. To do that I need to know more mod tyre weights. The tryall tyres especially because those are the only ones which are identical in both 26", 20" and 19". Everyone satisfied now? Can anyone help me out? "Question authority. Think for yourself. Free your mind."
  23. I want a 65mm rim because of the stability (no tyre flex) and so I can run lower tyre pressures. I run 24" and the 24" rim is lighter so if the 1150g can be drilled down to 900g then I'm guessing the 24" could be brought down to 800g. That is still lighter than a non drilled Sun Doublewide which I used to use back in the day (no currently on a drilled BMF ~630g). I probably won't substitute my BMF permanantly but I'd like to explore other possibilities. Course I could also get a 47mm Kris Holm 24" Tryall lookalike rim instead of the large marge. There is also the wow factor to take into account i.e. it would blow me away to look at my bike with that rim on! And so know you know WHY I want a to go silly wide, everyone satisfied?

    19" Tyres

    its not the 75g that worry me bud it the total weight of the tyre. I posted this topic cause I want to compare 19" tyre weights to 26" and 24".
  25. Glass

    19" Tyres

    Just curious to know what the weight of currently available 19" tyres are. Been looking around the net and only found that info on Maxxis Creepy Crawlers: Website says 975g but webcyclery says 1050g Can anyone help me out?
