It's not got discs has it? If so, it might not fit. If it hasn't, the bottom goes on the mudguard braze-ons and the long silver arms go on the braze-ons on the seat stays and if it doesn't have any, you need P-clips or you can get a seatpost collar with the fittings for a rack to replace/supplement your current one. That's it! Hey presto, bob's your auntie. Looks a sturdy enough rack too.
