Can't speak for your frame but I've fitted one to a small Kinesis frame. The bottom fixing lug on the frame is next to the drop out and the caliper is by Hope. If necessary, the stay on the carrier could be pushed further away from the hydraulic cable by inserting a couple of washers next to the frame (not necessary in this case). I've gently bent Topeak carriers without damage to widen for a good fit.

This fit my girlfriends 2009 Giant Talon with disk brakes without a problem...

I have Altura Dryline 56 panniers, which fit perfectly onto this rack. I realise that these panniers may have a different fitting system though.

my rear bike rack copes well with 2 fully loaded panniers... this might include my laptop and a book or two, a change of clothes, a school lunch, snacks, my water bottle and my cycling poncho for wet weather. all up it's equivalent to what i could comfortably carry on my back in a 25 litre pack.

Hi there. The rack tights to the rear bars of the frame.
Therefore the bike will need two pairs of small cylinders welded to the frame: two below the seat and two more near the weel axis. If you find those you'll be ok, cause the rack has an adjustable system in horizontal and two pairs of bars of different lenght for that fit below the seat.

These racks are different. The Super Tourist Rear Rack has heavy steel components that are used to connect it to the chain stays.

The rack you linked to on the Topeak website is lighter, and easier to install.

It does not have the QuickTrack plate. Look closely - it is a flat plate on top.
