Could anyone assist me in locating forks for an Isaac Kelvin pre 2006. They are tapered 1 1/8" at the top and marked as 33mm at the bottom headset.any suggestions greatly appreciated..
So far as I recall, the Isaac frames from then used a tapered 11/4 to 11/8 steerer. Currently 3TTT make several suitable forks, starting at around £200 new. Their UK distributor is I-Ride. Also, Kuota used the same dimensions on some of their framesets, I have used one of their forks on an Isaac Sonic, although they aren't easily available aftermarket....
Hope this helps.
