thats a nice bit of kit but way to expensive i think !!! mine was free but not as trick. i find pulling the clutch lever near the end also helps, still not as light as other bikes but a big improvement.
I had an old small screwdriver that I cut a groove in the blade, and gently tap in-between the head of the pin and the post if theirs enough room, the downward tap is safer that a side tap.
I suppose it depends on what hub you are using ? if its a wide one then the spokes will be further apart. the size (width) of the rim won't make any difference but a wider tyre might !!!!! are you using kat forks ?
got an old gear lever and cut it down, had to flatten it a bit but looks better than the bodgy one i made. 55mm hole centres if anyone is interested. the only drawback is i have no freeplay at the clutch lever to stop the drag but no slip when wound on.
