Ive only done a quick test ride so far, but the acid test is trying to change up to the bigger cogs when one has got bogged down on a gradient, always sure to cause a problem with the shimano chain, clicked in without a problem with the sram, fingers crossed for the future.
Update, been running the same pc830 since mar. Once the initial factory lube of the chain got it filthy dirty, I cleaned and relubed with parrifin wax. Found that unless it was very recently lubed then all the skipping issues on the rear cogs reappeared, (like fresh wax at least once a week), yes I can live with that, but not quite like the original sedis where it could be abused(in terms of not regular lube or clean) and still shift perfectly. it would be great if sram just reproduced the 1980s sedis product.
