However you cant use the gear cover, so this is strictly advised if you are on Tarmac. Not rallye. 64p gears do not like dirt and pebbles
Yes that's around the same I used when running non boosted 17.5T in TC, but is it same with boosted?
Well I'll just have to test tomorrow at the track
With 72T/35T 48P 5.34:1 I don't think I can use the gear cover either but I will only run indoors with this setup so it shouldn't matter.
