Current Projects chat and miscellany

So Just got my chinese carbon up and running after a long while :) It's nice, from what i've ridden but only problem is, it feels like it's slipping on the 4th and 5th ring on the cassette. All the other gears work perfectly, maybe cos i'm running DA cassette with 105 chain and mech? who knows

DA + 105 chain will make no difference to that sort of thing, just sounds like they're the sprockets you do most of your riding in, so they've worn out first.
