The diameter of the 6 holes for the bolts in these 6 hole sprocket supplied by Dieter are 1 mm minor than what we need to fix the sprocket to the spocket carrier of the Strada. You have to drill them 1 mm wider (if I remember it well).

Amazingly, the 36 tooth sprocket that MJCorse made for my Dart has exactly the same problem. It's made in duraluminium, so it might be easier to enlarge them with a round file... I say "might" because I didn't do it, and bolted it immediately on the wheel, having a heck of a tough time and, hopefully not, an abuse of the wheel threads

Alicante based MJCorse did a 36 for my Dart:

Easy because they make sprockets for Cagiva Freccia, from 36 up to an stupid 54 :lol:
