William trials Posted January 19, 2012 Report Share Posted January 19, 2012 hi, well if you ride 20" you should go for the 160 mm, but i don't say that you can't use 170 etc. but i would recommend the 160 mm trialtech. Quote Link to comment Share on other sites More sharing options...
Billers Posted January 19, 2012 Author Report Share Posted January 19, 2012 there is only 170mm left in stock, will it affect me greatly? Quote Link to comment Share on other sites More sharing options...
William trials Posted January 19, 2012 Report Share Posted January 19, 2012 well i don't know that much, but i would still recommend the 160 mm... go for the "echo sl" instead? here's the link: http://www.tartybikes.co.uk/cranks/echo_tr/c513p11196.html Quote Link to comment Share on other sites More sharing options...
trials owns Posted January 19, 2012 Report Share Posted January 19, 2012 A few top riders on here use 170mm, For better leverage for maximum power, But the pedalling will feel slightly lighter Quote Link to comment Share on other sites More sharing options...
