the brake calipers might not reach. i did a conversion with 700x28 and some generic regular road calipers. the calipers were 5-6mm short. if you have medium to long reach calipers then not problem, tektro r559 have more then enough reach and width for any 27" set up. it was easy to drill the fork. center punch, 1/8" drill bit, then 1/4" for the front and 5/16" with a little filing for the rear unless you have a non recessed nut caliper (disclaimer: dont just use my drill size, yours may be a different size and i hold no responsibility for any miscalculations). same for the rear bridge. i think the conversion would work for any non suspension mtb frame/fork, plus it will also have room for full fenders!
