Brilliant little devices.

They are great for all-weather commuting but they can barely dissipate heat and most designs need to drag a bit in orfer to work. You also have the problem of stopping with the cranks at dead centres, as with a fixie.

Re: Roller brake hub

Roller brakes are a little bit odd. Wheel removal can be a faff and they have inherent play, so the bike can be rocked fore and aft a bit with the brake on. They also need to be purged with the special grease regularly. They do stop well and have large cooling plates. The latter float in between the...

Re: Flicking stones damaging property.

I've had the odd stone ping from under a high pressure tyre and hit a car. It's embarrassing if the owner is sitting in it. MTB and car tyres don't throw them quite as far because the "spring" is a lot weaker at 30-40psi than at 140psi.

Re: Why is the front QR release always on the left?

Some racing types have the rear QR on the right so they can undo it and pull the rear mech back in one movement, for a quick wheel change. The QR doesn't care which side it's on.

Re: Velox rim tape woe - Hot weather?

The only reliable tape I've found that isn't too thick and doesn't crack or push through at high pressures is Specialized Rim Strip. Only comes in one width, though.

Re: Freewheel removal tool

To remove it without the tool (if you're not going to use it again): 1. Remove the freewheel adjustable bearing cone using a pin spanner or a hammer and punch. It unscrews clockwise. To get to the cone, you *may* need to remove the top sprocket or two. The top sprocket is normally screwed on (unscre...

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...
