I just purchased a Surly Pugsley project bike. The front hub isn't set up for a disc brake so I'm looking to install a cantilever brake. It has 65mm large marge rims. I've scoured the internets and haven't found a recommendation for non disc brakes for the pugsley.

What cantilever brakes are compatible/recommended for use with Surly Pugsley 100mm front fork and the larger marge rim?

  • Does your fork have rim brake bosses? Oct 24, 2011 at 13:07
  • I don't see any bosses in the picture on the site... EDIT: I take that back.

  • @heltonbiker yes there are brake bosses on my fork. The frame is a 2007 version. I'm guessing the fork is a similar vintage. Oct 24, 2011 at 21:28

Any medium-profile or low-profile cantilever brakes should work on the Pugsley; so long as you're using the Large Marge rims the effective cantilever post to rim spacing should be basically the same as a normal bike. The default spacing for most cantilever bosses is 80mm for use with a ~25mm wide rim. On the Pugsley the bosses are spaced 120mm for a 65mm rim.

The Shimano "link wire" style straddle cables will almost certainly be too short, For clearance, with whatever brake you use I'd plan on making it work with a high-quality yoke and a long straddle cable, as used on a wide-profile cantilever. You might even be most successful dialing in your own using a set of cable knarps.

  • Thanks for the good info and good call on the cable knarps, I can see those in my future! Oct 26, 2011 at 5:58
