I replaced a cheapo suspension fork with a Nashbar chromoly rigid fork and really like the way it feels. Continuing with the upgrades I thought I'd replace the C-Star V brakes with some quality Shimano Deore V brakes BUT this wasn't as easy as I suspected. While my brake bosses are apparently the correct diameter the shouldered portion near the attachment point on the fork is too long or perhaps more precisely the Shimano brake arm is too shallow. Either way they don't fit. The brake arms will not go on the boss far enough before bottoming out to allow the spring tail to go into the hole. I'm aware that there are both 10mm and 8mm bosses but can't seem to find any info or various sizes with regards to the length of the shoulder. There are obviously bosses made that these Shimano brakes will fit unless Shimano is sell these things and people are just putting them in their assorted parts boxes like I did. Does Shimano manufacture a unique brake boss just for their V brakes? The bike world and it's non standardization is maddening sometimes. Any help is greatly appreciated
call Nashbar support. New one on me.

something else is going on here. The brakes should fit. Take it to a bike shop have them look at it. If there is anything standardized as far as bicycles go. It is the brake bosses for canti's and V-brakes. Pics may help too if you can load some

I am a bit stumped on this one, Congrats you are only about the second person on here to ever do that! ha. Is it possible to send them back for a refund? I would go with Avid single digit 5 or 7 for replacements. Use them all the time.

Exactly the same problem here but with Avid SD7's not fitting the standard posts, ie the internal recess is not deep enough to clear the shoulder so they stand proud. Looks like shimano/avid have changed the standard or something. Haven't been able to find the correct posts so far other than some expensive titanium ones from ebay/aliexpress which show different 'standard' and 'shimano' posts. Anyone know of a supplier of cheaper steel ones?
Still can't believe there aren't more people coming across this problem, even in these disc brake times.
