Half of Team Grumpy go ceramic

I've just installed ceramic bearings in my H3s. This is done not so much with an eye on the claimed lower rolling resistance, but in the hope that I will no longer need to de-rust the rear H3 everytime I go out in the rain with it. Previously, I've changed the seals and also tried a new rear spindle, but somehow water does creep in.

Anyway, ceramic might provide a solution to that particular problem, but whilst ordering the bearings for the rear it seemed a good idea to do the front as well - so I did. I also went with top quality grade 5 bearings. It'll be interesting, then, to see if they make any difference. But how will I be able to tell?

well, that's what I thought too.

Did ceramic bearings help?

I have found that going tandem cycle touring in the Outer Hebrides adds nothing to one's time trialling speed!

Ah, you're back then.

Hard to say about the bearings - I've done three events in the last wek as I try to recover some form. But I'm starting from such a low base and all these courses are hard and tend to find you out if you're not 100%.

Initial findings, though, are that ceramic bearings might make the wheels spin gloriously when held in the hand (and they really do) but they slow you down seriously when you race. Well, it must be them that has caused me to put in such horrifyingly slow times this last week.

Methinks I have serious work to do in the coming months.
