Buy what you like; no-one really gives a damn. Just don't make out like it makes a big difference; it doesn't.

Re: Cycling Club Names, Z - A

Informal clubs I have encountered in Surrey pubs include:
Thursday Night WS (as printed on their T-shirts), and the
West-Horsley Independent Mens' Pedalling Society.

Re: 9 speed cassette: 12-36. Too spaced out for front double?

... I've ridden behind and studied the gearing use of people who advocate closely spaced gears and they don't shift any more often than I do. Rather than use the fine tuning as they claim, to maintain a constant cadence, what they actually seem to want this for is a closely-spaced selection of 'jus...

Re: 9 speed cassette: 12-36. Too spaced out for front double?

My modern touring bike has 3x9 gearing, 42-32-22 and the 12-36 cassette you ask about. It all works fine, giving me suitable gears for day rides and low enough ones for, for example, an unsupported tour of the Pyrenees, going over TdF cols such as the Aubisque and Tourmalet with a pair of panniers a...

Re: Specialized plug and play fender (a.k.a. mudguard) rattle

How about fitting a seat-stay bridge clip to the mudguard and threading a cable tie through the brake-bolt hole of the clip and round the stays. Probably best to thread the cable tie through the clip twice, once in each direction, to finish up with a symmetrical arrangement. Still a bit Heath Robins...

Re: Why you need aero wheels

AIUI, tennis balls are fluffy and golf balls are dimpled to make them go faster. Its to do with separation of the boundary layer. I would find it very easy to believe that hairy legs are faster than shaved ones. OTOH, if I squandered some of my unbelievable wealth on the services of a masseuse in or...

Re: Occasional chain suck - new components

I had bad chainsuck on a 26T steel inner on a triple (eventually found it was producing burrs where the teeth deformed slightly under pressure - even after filing them off they formed again so it wasn't a one off event). I had this too. After I filed off the burrs for the second or third time the p...

Old hat. Velocio built a bike with four chainrings over 100 years ago. There were two on each side, also two chains and two sprockets on each side, with gear selection by clutches.

Re: Double VS triple. Sheldon gears say 1.9 VS 1.8. Comparable?

On my elderly Roberts touring bike with a Stronglight Impact chainset I used to have a triple: 46-34-24t, but I found myself changing between outer and middle rings too often, so I removed the outer and changed the middle to a 40t (which remained aligned with the centre sprocket of my 9-speed 11-34t...

Re: Disc brakes pulling trike to one side

Only last weekend I fixed the front brakes on an 'Auntie' Rover 100 belonging to a friend. Braking caused a sharp pull to the right. The cause - leaking seals in the left hand caliper. You may claim that wasn't the cause but all I know is that after I fitted new seals it pulled up in a straight lin...
