Oh – my old Hope XC Pro silver hubs – now promoted back to best bike duty, and never touched in about 6 years – fab. They're not as sexy or noisy as the blue Hope Pro II singlespeed ones on the, erm, singlespeed, though.
I love the fact that it took me about 17 years of mountain biking to discover lock-on grips, and every flat barred bike has them on as a matter of course. When I say 'love' I mean, 'am annoyed at'… 😕
Bel Air RL saddles, too – I fear the day they stop making them, or 'improve' them or something.
Finally – my el cheapo Decathlon own brand black gilet. Brilliant bit of kit and cost me buttons, because I didn't want to spend loads on one as I didn't know if I'd use it. I do.
