Just checked out your blog mate.
when are you at Hampton downs next, would nice to check out your bike.

i see you have tried different front sprockets, do you have any spare one's?.



i am looking into running a 14 tooth 420 pitch instead of 520,but cant find anything unless i have it made which will cost the earth, it's just because i have an assortment of axle sprockets that are 420 pitch,and also they would be lighter.
