A friend of mine just had a custom bike built and although it fits great there is a 2 cm shoe overlap of the front wheel. The danger of this is making a hard turn and trying to straighten out with your foot then in the way. Criterium racers in particular could do this because they only stop pedalling at the absolute apex and then start again with the front wheel still turned.

Anyone else had any experience with this? I remember high siding because of this. Luckily not in a race to be run over by a hundred riders.

Custom build and shoe overlap? I would want my money back.


I think I'd want my money back only if I had specified "no overlap."
But I probably wouldn't bother to specify that. It just doesn't bother me.

It does perhaps illustrate an important point. When buying a custom
frame, do be sure to specify everything that's important to you.

Our now-ancient tandem was custom built for us. It was delayed for many
months. When we were finally called to pick it up, I found it was
painted the wrong color, it lacked some water bottle mounts and other
minor braze-ons I'd wanted, lacked the clear coat over the paint, and
(since I'd ordered the bike built up) had some equipment mistakes. The
most serious of those was a Phil rear hub that lacked left side
threading for a brake.

(Actually, the most serious problem was fitting track gauge instead of
tandem gauge fork blades. But I didn't know that until decades later,
when the forks snapped off.)

Anyway, Jim Bradford (the builder) said "Look, I'm leaving for my
honeymoon in a couple weeks. Do you want the bike or not?" I grumped
and took the bike. But if I'd given the guy written specifications for
every detail on some sort of official form, I might have avoided some
unpleasantness.


I'm not sure that a frame, with a 54 cm (center to center) top tube,
700c wheels and normal trail, can be built without toe overlap.

Of course, with a higher bottom bracket toe clearance increases but,
from measuring my own bike, the B.B would have to be 3" higher which
would probably end up with pretty strange looking bicycle :-)


I think that's the reason that somewhere around 1985, Bill Boston then
Georgena Terry started building road bikes with smaller front wheels.
