cheers mate! i dont actually know much about them other than they are shimano.. i got them for £17 from a second hand bike shop, i dont think there a matching set either haha
The closest one looks like 600 or Ultegra. BTW, as you have your chainring on the outer side of the spider, and if those are road cranks, how did you get your chainline to work? Your bike is my favourite fixed gear on Pinkbike,
yes they are road cranks, i used a bb with a 107mm axle that moved it all inwards towards the frame, i had to file off the lips that would hold the inner chainring as they were hitting the frame though, cheers mate
This one of the few conversions Ive ever come close to drooling over. Very nice job with the build! Definitely one of the best Ive seen! Also, what cranks are you using?
