Re: Which 3 splined driver for Sturmey Archer AM hub gear

A bog standard AW driver from a British made hub will fit an AM. A later Taiwanese N.I.G. driver won't. I have several hybrid AM/AW hubs; for an easy life, convert them to the normal AW toggle and clutch key and fit a 3-spline driver. You can even put an AM into an alloy SRF3 shell if you like: virt...

Re: Train reservations

Waste of time on GWR Class 800 trains. The "reserved" electronic signs are often switched off, and the bike space you reserved will be full of luggage, prams and surfboards anyway. They seem to be on a mission to make people buy estate cars.

Re: Radial Front Wheel build - spokes inside or outside the hub?

I've only ever seen them built heads-out, spokes-in. Personally, I don't trust hub flanges enough to build radial wheels, except on Bromptons, where it's necessary because they only used to sell one spoke length to fit ALL wheels (front radial, front x2 with SON-XS, rear x2).

Re: Bottom bracket - and tools - for 1986 Raleigh Road Ace

I still have a set of conventional BB spanners, including the six-dog lockring tool, pin spanner and fixed cup spanner. I thought I'd never use them again (except the fixed cup spanner, which gets used quite often to strip down old bikes*), then I bought a Ron Cooper with a mint Shimano 600 triicolo...

Re: Sachs and Sturmey Archer Compatibility

I would be on the lookout for NOS Sachs/SRAM spares, since SRAM stopped making or supporting IG hubs in 2017. The clutch keys tend to snap on the Torpedo and I would definitely buy those if you see them. FG 10,5 axle nuts are made by other people so should still be available. Still, be careful not t...

Re: brinelling

I'm with Jobst Brandt on this one (I know this isn't universally accepted, so forgive me, Brucey). The dents in the races, mainly the lower race, are always worst at the front and back of the races. With traditional caged ball headsets, road bikes suffer badly from it, MTBs not so much (even if they...

Re: Chainline for a FLip/ flop hub

It depends how much you're going to use the freewheel, and what type of chain you use. if the freewheel is there as a "get you home" device when you're really tired, and you have a bushingless chain (which most are these days), just optimise for the fixed side and let the freewheel side wo...

Re: Cyclus head tube reaming and facing tool

The reamer and facer are separable on the Cyclus tool. I haven't tried the facer alone, so I don't know if it will work like that. It does the job very well. I had to do a couple of chromed frames with it (this is not good for the tool) but it still faces other frames cleanly and doesn't chip the pa...

Re: Moulton TSR rear tyre wear.

Rear tyre wear is mostly through scrub on the road, especially when honking out of the saddle. Fixies with no rear brake get through rear tyres just as quickly, unless you're an inveterate skid merchant on a normal bike - unlikely if you're over 14 and have to pay for your own stuff. Any sideways fl...

Re: Worst Nightmare Snapped Handlebars

I was with Steve Abraham when he broke his handlebars trying to climb Smalldean Lane (a wall-like 1 in 4 near High Wycombe) on an 86" fixie. He repositioned the bar clamp over the break and rode onto London, then back to Milton Keynes. :D This sounds like one of those Chuck Norris jokes but it'...

Re: is it the end of 23mm tyres???

There isn't much decent engineering in the bike world, so things go around and come around. There's also a proliferation of standards, many of which don't work very well (PF30?) for things like headsets and BBs when one was good enough for a century. The bike nanufacturers want you to buy a whole ne...

Re: is it the end of 23mm tyres???

23mm is also the widest that will fit my track bike. A 25 or 28mm tyre may roll better but rolling resistance isn't the whole story; a 23mm will weigh less and have less air resistance. I sed to have (and liked) 18mm tyres.

It's fashion, I think.

Re: Can you swap from a 1+1/8 fork steerer, to a 1" steerer?

There are also headsets that do this all on one go. Chris King even made one for 1 1/4" to 1 1/8" (called Devolution because 1 1/4" is Fisher Evolution size*).

*1 1/8" is Tioga Avenger size
