Touring bikes typically have lower bottom brackets than race bikes in order to make them more stable when loaded. Furthermore, toe overlap is a bigger concern. This means more to worry about both downward and forward of the cranks. | |

| Jul 30, 2013 at 12:06 | comment | added | Vorac | @trailmax, people vary from, for example 1.60m to 2.00m. This is 25% difference. The difference from 165 to 175mm is only 6%. And this is not considering the vast diversity of riding styles - downhill, touring, city. | |

| Jul 30, 2013 at 10:05 | comment | added | Vorac | @cherouvim, indeed. I do not feel that half a centimeter could possibly make a difference. And touring bikes have plenty of clearance to be able to use much longer arms, for example 220mm. | |
| Jul 30, 2013 at 10:01 | comment | added | cherouvim | Are you asking about the 5mm difference between 170 and 175? | |
