anither daft question are the rr and sp riders seat pads the same as i need one and dont know if they are the same or not, my budget is taking a bit of a hammering for hybrid no.2 and have to be carefull with the pennies.

Yes, i have an SP seat unit for my hybrid (the rr subframe definately doesn't fit.) However the seat pad lines up perfectly.

Yes , as said. The seat pads are the same!
