Singlespeed & Fixed Gear - campagnolo pista crankset questions

hello

Im new to this game and am doing some research on cranksets, google has helped me to a certain extent but now i need some hands on advice, any help is appreciated.

Q: Im investing in a Vigorelli Cinelli frame and wanted to try and source some vintage/older style cranksets to accompany this frame. I see alot of 165mm campag cranks but wondered if they ever made them in a 175mm version?

Q: Im also struggling to find the bottom Bracket sizing/dimensions for the vigorelli, Id ideally like to know if it's easy enough to source a bracket to fit these cranks to this frame.

Q: lastly, I gather it's possible to fit some shimano SPD's to the older style campag cranks mentioned above. ( Im probably going to be crucified for even thinking this!)

I'll be using this bike to commute.

thanks

The pedals will work.

All you need to know about bottom bracket compatibility as far as frames go is whether it is English (68mm) or Italian (70mm) threaded. Other than that, find the one that matches the crankset you want.

Great thanks for the info

Sounds like a interesting build. Be sure to post up when you get it completed.

you want your first frame to be a cinelli vigorelli? brave. kudos to you.

also for the 175 vs 165, i would recommend otherwise. because you will always be pedaling, you might end up striking the floor and then hurting yourself. i've done this with even a 165.

You do realize the cost of what you want to build right?
Just the Vigorelli and Campy Record Pista crankset would put over the $1k mark.
Then you still need a set of wheels, and a handlebar, saddle, seatpost...

If you're just starting to ride fixed and/or just using it to commute, I would suggest starting out with something more solid first. Something you can experiment with and beat up to get to know riding fixed.
The cheapest option would be something from bikesdirect.

Also, most fixed gear bikes have 165mm crankarms to lower the chance of pedal strike, but the advantages of a longer crank like a 170m is it offers more leverage, which would allow you push a gearing more easily. However, if your gearing is low, which means you constantly need to spin at a high cadence, shorter cranks allow you to do that better.

Yes i guess Im dropping in at the deep/top end. I have been seriously considering stepping back and starting out on a beater bike...
Im 6'1 and am kind of torn between choosing a 170mm crank VS a 165mm. Im used to a 175mm but seeing as riding fixed is a totally new ball game I figure the "used to" logic doesn't hold any water. I guess what I find appealing about the 165mm is that they'll hopefully help alleviate the toe clearance issues though Im aware that this is always going to be an issue with track bikes on the street.

What are your thoughts on the "long legs" VS " toe clearance" query of mine?

Thanks for all the feedback guys, I'm learning loads here.

the crank arms matter less than seat hieght. its alot easier to stike the ground with 175's. there are vintage dura ace and sugino cranks that have the same look as the campy ones and are just as decent for a little less.
