Well, after two years of regular use, the Comp rear hub has started to play up. Electronics and power measurement are fine, but one of the pawls jammed, causing it to slip to the next pawl after coasting. It's been doing this for a while, but I though it was a worn chain/chain ring until I swapped it to my other bike.
Of course, once I stripped the hub, I found one of the new bearings I fitted a while back was stuffed (don't trust "ABEC5" to be 'quality', in this case it had been used as a brand name to con purchasers and was a cheap crappy one!). So a clean-and-lube turned into a major service. Luckily, I had bought some DECENT bearings and put them away for just this occasion. I also have a spare freehub, but it's an alloy version, so it's a "last resort" replacement.
The freehub is working O.K. again, but the back face of the pawls where they rotate in the freehub is galled and the tips of the pawls where they lock into the ratchet ring are deformed. It's a very quiet freehub now, nothing like the noises they make when they are new. I might buy some spares while they are still available... $50 US per freehub plus shipping
I ride, therefore I am. But don't ride into harm's way.
...real cyclists don't have squeaky chains...
