Any question answered...

I hope so: I've built someone a TT bike without a NW chainring or a clutched mech...

The advice I got was that if you weren't using a wide-range cassette, chain slap was unlikely and so therefore was the risk of unshipping your chain.

The chainring does have full height teeth and no ramps or pins; the cassette is 12-25.

A clutched rear mech seems the most effective precaution to me, as it addresses the problem (chain slap) rather than the symptoms.

You better believe it! :)

Had 1x9 on the cargo bike for ages with no clutch or NW chainring, that thing gets bumped around a lot and has an extra long chain that never fell off.

Great, that's £30 saved then.

I've been running 1x10 on the road all winter without narrow-wide chainring or clutch mech without problem - Sram Red shifter, Dura-Ace 7800 crank and Dura-Ace 44t chainring, Sram Force rear mech, Ultegra 12-25 cassette.

What kind of rings are you using? Regular rings with shifting aids like ramps and pins, or 3/32 single-speed rings?

Dura-Ace 7800 44t inner chainring - so no ramps or pins - in the outer ring position.

Is it possible to buy bearing races for a solid rear track axle with cartridge (sealed) bearings?

The bearings are 60010.

I am trying to convert a disc wheel for track use, and I've done it before, but can't remember how I got the parts last time. I think someone gave me some bits and pieces which worked with a standard solid rear axle.

Thanks.

I'm aware that 'race' might not be the right word. Whatever the cartridges sit on is what I'm after.

Have a look on @Scilly.Suffolk 's Yokel Motion 2 build, the bearing seats you need are the same although you'll obviously need different spacers and a longer axle.

Has anyone used a Mio Fuse HRM wrist strap? @Cycliste is thinking of buying one due to her inexplicable dislike of chest straps.

I have used the MIO Link and it worked well.

Interested to see how well they work. I don't think I've had a correct readout from a chest hrm yet. (Garmin ones, online says may be because of jersey material).

perfect excuse to participate in the naked bike ride - unless they boot you off for wearing the HRM

So long as it doesn't obscure the man-nipples...

I never understood the panic with not using NW rings and clutch mechs - I ran a single 44t XTR on my old 8 speed Kona for years without any issues hammering it around quarries.

unless they boot you off for wearing the HRM

For a group supposedly keen on nature, WNBR participants seem remarkably keen on defacing their bodies with paint, so I can't see that a bit of elastic strap will cause offence. The PETA-tendency might not have loved the leather version (bonus points for anybody who knows what year this was)

You won't have to spend it on trousers.

Are speedos acceptable when swimming as an adult? Rather than fucking board shorts or square shorts?

"speedo"

Sounds like "peedo".

I think you have your answer.

Right then. What does one wear to swim properly in?

Yes. Jammers.

Mine are Speedo (or is that Spaedo).

Jammers. Always jammers.
