trialsalot Posted February 13, 2014 Report Share Posted February 13, 2014 Hi! So I've currently got a Because 20" and the wheel is pretty far forward. So far forward in fact that the tyre catches the frame and my brake is absolutely terrible. Even through the brake clamps are slotted I need them to slide up another 3-4mm just to get the complete pad to contact the rim. The real question is that I've purchased a half link and was wandering how much after installation will my wheel move back? I run the standard 18-12 gearing. It's annoying because my brake set up should be a monster (adm and echo sl mounts) but it's far from powerful. Cheers guys! Quote Link to comment Share on other sites More sharing options...

thinkdougie Posted February 13, 2014 Report Share Posted February 13, 2014 Try TNN clamps they have a lot of adjustment Quote Link to comment Share on other sites More sharing options...

Lord Banks Posted February 13, 2014 Report Share Posted February 13, 2014 Chains usually come with a lot to spare, so you’ll be able to have your wheel as far back as you like. Quote Link to comment Share on other sites More sharing options...
niconj Posted February 13, 2014 Report Share Posted February 13, 2014 (edited) I know it's not a representative study but sometimes I think that Because frames aren't manufactured well. My 24'' is supposed to be run w/ 18/14 which makes the chain either too short, or too long. Even with 18/15 it's a tight fit.

monkeyseemonkeydo Posted February 13, 2014 Report Share Posted February 13, 2014 cheers Adam...that'll sort it nicely! For reference that value comes from the fact that bike chains have a 1/2" pitch (that is each pin is 1/2" or 12.7mm apart) so adding a half link extends the chain by 1/2" but because the chain wraps doubles up on itself to create a loop it actually alters the wheel position by half that or 6.35mm. 2 Quote Link to comment Share on other sites More sharing options...
