My Tricross has cantilever brakes. The ones at the front are easy enough to adjust but the ones at the back just seem like more of a pain. So I was wondering if it's a sensible proposition to change them for caliper brakes, something like this, which seem like they are much easier to work with.

If it makes a difference, it's a 2009 tricross sport triple and I've had the change made so the front brake cable is seated under the fork rather than on the stem (a change Specialized made from 2010 onwards to prevent juddering when using the front brake)
