Rusevelt Posted April 6, 2009 Report Share Posted April 6, 2009 Way harder to pedal for trials specific techniques so dont do it. unless you wanna do high speed bmx style bunnyhop gaps..... Quote Link to comment Share on other sites More sharing options...

Hendrix Posted April 6, 2009 Report Share Posted April 6, 2009 Well, I'm currently running 16 rear, 22 front. That is crazy heavy for me, and although gives the speed to get up some objects, restricts you on many other moves.I'll be going to 18 soon - which I think is ok. Anyone want to help me out here?

Hendrix Posted April 6, 2009 Report Share Posted April 6, 2009 22:18 is fine mate, should work pretty nice...supposedly comparable to 18:16?It's great for BMX style stuff, or attempting to get up bigger stuff that needs run up (big for me anyway) - but it's SO heavy for small stuff. 18 shall be ordered on the 27th! Cheers man! Quote Link to comment Share on other sites More sharing options...
matt rushton Posted April 6, 2009 Report Share Posted April 6, 2009 I run 16:14 which is the best setup for trials, slightly heaver than 18:16 I think. Quote Link to comment Share on other sites More sharing options...
Echo-Scott Posted April 6, 2009 Report Share Posted April 6, 2009 Chain snappingly shite.How do smaller cogs acctully result in snapping chains?I know smaller cogs and all that will make it easyer for your chain to skip/come off but how will it effect the strength/load at which the chain will snap?

ogre Posted April 6, 2009 Report Share Posted April 6, 2009 the same amount of force, over a smaller area, means theres more pressure on the chain. Quote Link to comment Share on other sites More sharing options...
psycholist Posted April 7, 2009 Report Share Posted April 7, 2009 (edited) Also a smaller front sprocket means higher chain tension to transmit the same torque from the cranks - going from an 18T to a 16T front sprocket increases the chain tension for the same pedal load by 12.5%... Going from a 18 to a 22T drops it by 18%. This is why you can get away with 8 or 9 speed chains with a 22T chainring (If you're careful), but on an 18T chainring having the chain snap is nearly certain unless you run a BMX chain unless you never do gaps.Remember that a 10T cog has less than 5 teeth carrying the whole load from the chain, so you'll get plenty of premature chain and sprocket damage compared to say a 15T cog where 7 teeth (40% more) carry the load...

ZHI-sam Posted April 7, 2009 Report Share Posted April 7, 2009 whats 18/15 like on 175 cranks? im on 18/13 atm and its very heavy Quote Link to comment Share on other sites More sharing options...
Tha Goat Posted April 7, 2009 Report Share Posted April 7, 2009 (edited) I'm running 20-16 atm on 165mm cranks and I am still finding it tough to get used to. It feels too easy for ups and stuff, unlike the 20-14 on the same cranks I was running. Edited April 7, 2009 by Tha Goat Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted April 7, 2009 Report Share Posted April 7, 2009 I love mod, just because its universally accepted as 18:12. =D Quote Link to comment Share on other sites More sharing options...
