Although time needs to be spent getting the setup right, I have never had a problem with cantilever brakes and I like the simplicity. After some fiddling on the Surly Cross Check I settled on the original Tektro Oryx for the rear, with pads swapped out for KoolStop Salmon MTBs. The Oryx never performed well on the front and I now have SRAM Avid Shorty Ultimates, but again I changed the stock SwissStop pads for KoolStop Salmon MTBs. The Shorty Ultimates are very good, but the fitting bolts are tiny and I do worry about rounding the minuscule torx and allen key bolts.
The World Tour frame also takes cantilever brakes. I went for Paul Touring Cantilever brakes front and rear and for once have kept the original Salmon pads that come installed. They are quite expensive but are very obviously well made and performance has been very good almost from the first ride, with plenty of feel though the front benefit from a good bit of toeing in.
I think they look pretty good as part of a more traditional build too, I don’t think the bike would have looked right with something modern like Shorty Ultimates.
