With 21.5T on pretty open course what FDR should I start from? 4.0? 3.5?
I will need a smaller Spur as well.
Where do you buy smaller spur than 78T 48p or 96T 64p?
Thanks.
RW Racing are almost a standard for aftermarket spurs and pinions in the UK.
Not sure where you can get them in the US, but you want to look for their Xray specific spurs.
