That was the problem I had with the E3, finding a 1" steerer fork, I'd got some RC36's but needed a 1" steerer and shim (easy at a price but money was tight), then as luck would have it whilst picking up some other bits at my very small lbs (and chatting to the guy) he pulled a pair os NOS Mozo pro's off the shelf with a 1" steerer, I offered to try and sell them on here for him and he said £20 and there yours and you can do what you like with them , so they're on the bike , the RC36's got sold (for a lot more than the Mozo's but they cost me a lot more) and the Mozo's were used and they semm to work fine, no where near as nice as the Fox's on my Spesh but they certainly do the job I wanted on the Orange (disc tabs and a bit of give for my wrists) so I'm happy.
If it makes you use it then mod it to suit.
