Like the idea of the T-Rex, have had a quick go on a bike with one, and can confirm that I hate the forced jump from 19-15 tooth cogs by emitting the 17T.
You can buy a 16T Dura-Ace 7900 (10spd) cog on it’s own, without having to buy the rest of the cassette. RRP is an almost reasonable £8.99. Has anybody tried junking their 17 and 15T cogs and fitting a 16T in place on a T-Rex?
I know one up components offer this on their version, but they’re in the states, and I get trade discount on Hope too, so if makes sense to keep it British.
Whilst we’re at it, how well does an XT medium cage clutch mech shift on a T-Rex adapted cassette? Will the B- Tension screw go in far enough?
