Bike fit: saddle-to-bar drop and seat tube angle?

Ok I can accept my femur may be shorter, but so is my lower leg, trunk length arm length etc. So overall all measurements are shorter. That being the case then the seat tube angle should be similar, just top tube length on standover height should change. If you could change *all* the measurements, that'd work. However, it doesn't work that way, since the wheels are a fixed size. Jasper |

Peter Simple...making the ST steeper minimizes toe overlap. Take two 52cm bikes with the same length TT, one with a 73 degree ST and one with a 75 degree ST. The 73 degree bike's steerer (and consequently, front wheel) will be ~1.5cm closer to the BB than the 75 degree bike. While most readers will agree that this isn't a big deal on the open road, bike manufacturers realize the implications that 1.5cm may have. Specifically, when that distance may make the difference between a potential customer brushing a toe on the front tire or wrecking in the parking lot during his/her slo-mo test ride (and thus, deciding not to purchase the bike), guess what most bike manufacturers will do... |
