how the bloody hell is an 18 t sprocket going to work... i dont understand,
1) wont the chain hit the chain stays?
2) how will the support screw be squashed into the sprocket which connects it to the crank arm?... it hardy fits on a 25t
3) if thats possible wont you need special crank arms with support screw housings which have them even lower down the crank arm?
4) will a 5t drive fit on a casstte hub?
5) if a 5t cassette is possile it will probably = massive price on a special casstte hub?
and finally, why would you need such a small sprocket and why would you be willing to pay that much money for them??
P.S. please enlighten me with knowlagable replies
