Turns out that shoe overlap is common. Especially among pro climbers who are small and have short arms.

So why would you want your money back? Tell us HOW this overlap can have any effect? I had an old Motobecane that had overlap. I managed to crash the bike because of this but at a standstill. Would you want your money back from Motobecane?

Do you suppose a company that has been building custom bikes for 60 years doesn't know what they're doing?

I'm not trying to insult you. I'm suggesting that if you don't have any direct experience with this sort of thing just making comments isn't helpful.


It may make the bike bike not-race-legal.

UCI CLARIFICATION GUIDE OF THE UCI TECHNICAL REGULATION quotes

ARTICLE 1.3.009: "The bicycle should have handlebars which allow it to
be ridden and manoeuvred in any circumstances and in complete safety.”

and adds the comentary: " ... Bicycles shall have at least 89 mm
clearance between the pedal spindle and the front tyre when turned to
any position in accordance with the requirements of the EN14781 safety
standard to not be hindered when turning."


What does it say about mounting 175 mm cranks on that bike with 89mm clearance?


If it has 89mm clearance with 175s then you can ride it with 175s. If
it has only 90 mm clearance with 165s then you can't ride it with
175s. You don't measure a frame, you measure a complete bike. Legal
with 165 mm cranks and not legal with 175s is possible. One might
question the sanity of some of the UCI rules, and of course they don't
apply to non-racers, but thems the rules none the less. So if you
spring for a custom bike with the intent to race it, and are not
allowed to race, you might reasonably want your money back. Assuming,
of course, the builder knew your intent and crank size.
