Part 2 this week - chainring- I have a 28t fitted from standard on my XX1 chainset (the smallest you can get) and is a perfect size with the XX1 cassette / 4" tyres & County Durhams terrain/climbs. Again as the chain i havent had any problems with the chainring and not done anything apart from wash/clean it now and again. The coloured anodising has worn off in places on the teeth but apart from that its perfect. It is not showing any signs of hooking/major wear yet, i was expecting to be replacing it on a regular basis due to its the only chainring on the front and is very small. I bought a spare 28t again for 'just in case garage stock' or as a replacement when the original wears out. I was quite hard to find a 28t in the uk as all the stock seems to be sold out and not replaced. Plenty 30+t options but not 28t so not a huge amount of discounted prices. Below is the blurb from sram - Replacement chain rings in 76mm BCD for XX1 cranks. Replace a worn out ring or swap to change gearing; crank removal not required.Ratios Available in 28T, 30T, 32T, 34T, 36T, 38T
Recommended Group XX1
