Did Erv2 520 Chain
Did Erv2 520 Chain . But is the new did chain worth the extra money? 520 size with 120 links or 130 links. BSR Our Bikes from www.ballsacracing.com Apparently it is quite important to get the correct master link, even for the same brand of chain (local shops had did master links but not the correct one, and were adamant that i would need the correct one). Gold colour on outer links, inner links natural steel colour. 2% lighter and 15% longer lifespan;
