I was laughing the other day at Dean's description of his unloved primary chain in the latest DicE, until it occurred to me that I hadn't checked mine in a long, long time.
The manual says it's something you should check and adjust weekly. Er, OK. Didn't anyone have better things to do in 1952? Anyway, predictably my chain had about and inch and a half too much play, so that's one less task off the long, long maintenance list.
Next: work out why my battery is working a three-day week.
