Street cranks lenght

Hi everyone!
Sorry for my english im from czech rep.
I have 140 mm trial cranks but i want to ride a streets.
For street riding i rollin with these to slow.
Next month i want to buy a new cranks for street.
I think that i buy 125 KH moment.
Is this cranks good for street or its too short (for rails as.).
Thanks for yours opinions !

Best regards from czech by Peter !

If you are on a trials uni, then 125 mm cranks should be fine for street. I do some light street and trials on my KH trials uni. I haven’t done any rails, but I do crank grabs on benches, etc.

you have 125 cranks?

Yes, I’ve always had 125mm cranks on my KH trials.
