Hi Robbie,
I will be using something a little taller than Oulton. Perhaps 1 tooth smaller on the rear sprocket than Oulton.
This is very much a guess as I dont know how steep the climb from the old hairpin is - any suggestions, chaps?
Spoken to George Farenden - he reckons its similar to Brands GP cicuit, which on the TZ was 1 tooth smaller on rear sprocket than the short circuit.
Hope this helps
