Campag is ISO

Mid-50s and commuting fixed through west London on 74”, which gets tough in the Chiltern Hills. Need to sort out some niggling knee pain this winter that is probably the aftereffects of significant broken bones in my youth. Riding gears helps a little but not heaps. The pain is making stairs quite uncomfortable now and the next PBP is going to difficult otherwise.

It will be difficult reshaping head tube enough to let the bearings turn freely. Even if you mostly get it right, you are highly likely to have a draggy bearing that wears prematurely. For a headset bearing, this might be acceptable. They don’t typically wear out, instead dying by corrosion, contamination and brinelling.

If it was a steel head tube, you could bash away at it until you thought it was good enough and likely have enough meat on the head tube to cut the bearing seat round again. Aluminium, not so much.

Cracking of the head tube bearing seat while riding afterwards, you could possibly ride to a stop but the bearing might jam. That would put you on the ground instantly.

Your choice to try to fix it, I wouldn’t.

In past years, my partner has raised some dosh towards Harrisons Fund while doing the Rapha 500 and they have sent out a suitable patch. I would guess that they are likely to do so again.

The frame tubes on an Alan were opposite threaded, like a turnbuckle. Depending on which lug had cracked, you had to partially or fully disassemble the frame to replace the lug and reassemble it in reverse order.

The bonded Vitus and Peugeot frames of the same era used similar strength tubes of much the diameters as Alan. I figured the Alan’s threading added a little extra security if they disbonded.

Bonded carbon frames of that era are wallhangings now IMHO. The combination of carbon, Al and sweat forms a battery and the resulting galvanic corrosion promotes disbonding. Later frames used fibreglass between the carbon and Al as insulation. The bonded Al frames avoided that degradation mechanism and I would still ride the Al frames.

There were a few bonded Al lugs/ carbon tubes frames that followed Vitus and Alan e.g. SR Litage, Trek and Look.

Yes, the FWC bloke has some history for being a bit of a shit.

Does somebody do the same sort of thing for eTap? I have a Red 11sp with a stuck pivot that I have not tackled yet.

There is a racing tricycle forum https://www.tapatalk.com/groups/on3wheels/

The older blokes on there discuss all of the eBay, etc. trikes that are up for sale. There are also racing trikes advertised in Tricycle Association journal that are often priced ‘for a good home’. His height means that he will have much more choice of SH trikes than I did.

Riding a racing trike isn’t necessarily easy. The ingrained reflexes of a bike rider are exactly opposite those needed to ride a trike. A gentle test ride in an empty car park and an expectation of an adaption period would be sensible. It took me quite a while before I felt comfortable riding my trike.

Front rack kickstands only work when combined with a main kickstand, usually rear axle.

Most mudguards have a limited lifespan when supporting a headlight that contains reasonably-sized batteries.

Yup, #7 for me and #6 for the Young Lady. Haven’t decided what machine to ride this time but I’m sure it will be fun.

Conti

The first Saturdays in September and November are big cycle jumbles near London. There are railway and Underground stations a short bike ride from the Epilepsy Society, Chesham Lane, Chalfont St Peter SL9 0RJ.

There are two different ways to mount double straps. TTT’s photograph holds the front of the foot down and spreads the strap compression over a wider area, so more comfortable. Probably better for road riding or long track races.

The other way is to have one strap in the normal position and the other looped through the pedal’s backplate (more or less what is in that montage). That way makes it just about impossible to pull a foot but concentrates the strap compression on your foot. Better for pure track sprinters but a somewhat courageous choice on the road.

Yes, he was right at the front of the elevated chainstay trend. So many bits on that bike that I never saw in real life back in the day.

Pantour hubs had durability issues. From vague memory, excessive bearing wear and splitting suspension elastomers. Replacement elastomers are rare.

Mind you, I have not owned a Pantour hub.

I’m really sorry to hear this. I figured that he would go on for decades yet, rubbishing ill-thought through cycle designs from his recumbent/ rocking chair.

Mike is one of the most opinionated (but smart) people I know and I enjoyed listening to his pragmatic but off-beam solutions to problems that few others have ever thought hard about. Not always the right solutions mind you but always with good reasons for them. He was right more often about bikes than just about anybody else I know.

Your Ciocc is Italian thread? Not every LBS has Italian taps.

Rose is #11 on trike too. I am the fat trikie starting 3 minutes later. Two decades ago, I was #13 on a bike.

I will be riding, very much at the lanterne rouge end of the field, on three wheels.

Isn’t this event a fundraiser for LCC?

Haven’t they stopped making the Voyager Hyper?

I tended to edge up through the season as fitness increased, 88-92”.

Make sure the cone adjustment is correct. Excessive preload won’t be a good idea.
