TrialsNorth Posted December 28, 2009 Report Share Posted December 28, 2009 I'm building my first trials bike but i'm lost on which gearing I need in the front and back, also on what hubs to get. Soo i'm hoping you guys can point me in the right direction. I started trials with an old XC bike that I slowly modded into a 26" bike but never touched the gears. What are you guys using in the front/back for sprockets and cogs? I plan to use no tensioner if I can. What brand of hubs and cranks do you recommend? I've heard alot of about king, echo and a bit about hope hubs. The trials community here in my town is only 10 people or so..haha.Here's my part list atm, and it defers from the 2 pictures as their some parts from my XC bike.- Frame: 08' Czar long- Forks: Echo urban- Front hub: ??- Rear hub: ??- Head set: Echo- Crank: ??- Freewheel: ??- Front brake: Funn Drop In- Rear brake: Magura HS33 with braided hose- Brake pads: Rockman rockpads- Front rim: Rhyno Lite- Back rim: Alexrims DX32- Tyres: Maxxis Holy Rollers- Grips: Funn white Combat Gripps- Steam: Simtra Re'Sy'Stem- Handlebars: Simtra black McSkinny- Chain: KMC- Rear Sprocket: ??- Tensioner: None- Bottom bracket: Echo BB 128 x 68- Pedals: Inspired platforms Quote Link to comment Share on other sites More sharing options...
HargrovesToby Posted December 28, 2009 Report Share Posted December 28, 2009 ok, my view, i always run front freewheel, i dont use bash much but it suits me. I run a fixed rear hub, a trialtech, with a 15 tooth screw on hub, and an 18 tooth freewheel. works perfectly, not to heavy and not to flicky. You could run a rear freehub, like a pro trials hub, but in my experience they are heavier and not as manmy engagements, plus freewheels are easier and cheaper to repair/replace! could run a 20 tooth front and 16 tooth or 17 tooth rear? toby Quote Link to comment Share on other sites More sharing options...
Ullapool Trials Rider Posted December 28, 2009 Report Share Posted December 28, 2009 Cranks: Try to get some CNC'd cranks as they are lighterFreewheel: A Tensile 60 click is a reliable freewheel at a good price. Make sure it is an 18 tooth as this makes a really good gear ratio of 18:12 with a 12 tooth sprocketSprocket: As i said above, try to get a 12 tooth sprocket so you have an 18:12 gear ratio because this is used by loads of riders.Don't know much about hubs so someone else will have to recommend one to you.

ghostrider88 Posted December 28, 2009 Report Share Posted December 28, 2009 (edited) 18:15/16,Echo TR is better freewheel than tensile and costs the same.Trialtech/echo cranks are durable and cheap.rear hub?Something with fixed sprocket or casette.And change that stem please!

dandadude Posted December 28, 2009 Report Share Posted December 28, 2009 To be fair the front hub isnt too important in my eyes, mostly just rolls and dosnt take hardly any stress compared to the rear so upgrade that last. For rear hubs its really your budget, hope pro 2s are favoured by many and in my opinion the nicest hub on the market, i would like to get one myself again in the near future On the crank side of things if your going for a freehub on the back theres a lot of choice in terms of cranks. Most echo, zoo etc cranks are strong and will do the job. Middleburns are the nicest in my opinion but again thats your choice. Again bashguard choice is up to you there are many options available.Obviously if your going for front freewheel ignore most of what i wrote above as you will need a fixed rear hub rather than freehub however i have never run a front freewheel so cant really offer much advice on them. I would definetly advice using a chain tensioner with vertical dropouts, its very unlikely you wil get an exact chain length that doesn't need tensioning, plus tensioners are cheap or you can make one yourself fairly easily out of just about anything springy lol.In terms of gearing you usually get a 20 or 22tooth front chainring with either 16,17 or 18 rear sprocket. I personally run 22/18... well I think i do lol.I would also recomend going second hand for a lot of this stuff it will save you loads and to be fair cranks and bashguards etc soon look second hand with the abuse it gets through trials. Plus when your validated the buy/sell forum on here is great. Sorry if i rambled too much but hope that helped Dan Quote Link to comment Share on other sites More sharing options...
