Re: Disc front hub

A higher flange slightly improves the bracing angle, which means the spokes don't have to be as tight. This makes the tensions more equal (probably not completely so) from side to side.

Re: Brompton S6L refurb

Budget for a new rear triangle if rust is present. They rust out underneath the powdercoat and suddenly crack, often at one of the bridges. I might have a repaired LH pedal in the Crypt of Crap. The new bearing is held in with strong Loctite as well as the usual interference fit. Brompton peen the b...

Re: Securing helicoil into crank

Some grades of Loctite (e.g. 603) are very oil-resistant and need 250 deg C heat to remove the fitting later. That would be ideal.

Re: Lacing a front wheel

I do them so the outside spokes take the braking torque.

Re: Front centre pull cable hanger..

It's Cannondale Force 40 without the special boss. Everyone hated Force 40, although the Dia-Compe 986 brakes it shipped with were unusually hard to set up and may not have helped.

Re: Hub gear identification

It's the same as a Spectro T3 if you need parts. These are getting trickier as SRAM pulled the plug on hub gears 3 years ago, including ALL spares. Just like that.

Not to mention the Mini.

Funny how nobody's resurrected the Allegro name.

The Vanden Plas, possibly the ugliest car ever made, has quite a following now. You'd pay £5000 for a nice one.

Re: Dawes to stop making the Galaxy due to lack of demand...

I also had a Subway made in Vietnam. I assumed they'd be a pretty good bike manufacturing nation, since bikes are still mass transport there (or were at the time).

Re: Is my Dented Jamis Nova Sport aluminium Frame salvageable?

Down tubes are loaded in tension and in torsion, so a sudden collapse is unlikely but it will probably crack quite soon. Bin it.

Re: Bottom bracket problem

The LH cup doesn't go all the way in if the shell is slightly narrow. You notice this more with a cartridge unit than with the old cup-and-cone type, which always left some thread exposed for the lockring.

It's a 2018 model. I suspect the Hewitt was no lightweight.

I don't know about Galaxy weights but my LHT frameset is a couple of ounces lighter than my old 631 Hewitt Cheviot frameset.

Re: Dawes to stop making the Galaxy due to lack of demand...

The LHT only used 26" for the smaller sizes, which allows a better frame design. The fall in 26" popularity might give them a bit of a problem. You can make small frames with 700c wheels but they're not right; toe overlap has to be avoided for off-the-peg bikes under BS6102 and this result...
