For us UK lot :

I'll be competing in the BRCA 19t series this year coming and if it isn't such a big question to ask can you guys/gals advise me on gearing for these tracks please , i'll be using mainly the Atlas (Blue can) and C2 (Silver can)

Snetterton
WLRC
Southend
Bedworth
Wrexham
Stafford
Cotswold (i've got a gearing for this with a Atlas but would also like a gearing on a C2)
