...and sjsc have NOS hubs, it would be easy to swap the internal into a 40 hole shell...

A brand new hub

No personal experience, but you could ask this chap..

He certainly services/ fixes them. Could teach you how to as well

I’ve watched a few YouTube videos about mr millyards motorcycle creations, but I didn’t know he had built up any bikes... https://www.youtube.com/watch?v=iUak9sqJmnM
I love the clever concealed transmission! I’m sure there must be some downsides, but his ability to turn his imagination into reality is pretty impressive.. great shed engineering!

required.

If you want this functionality, I suggest that you use a fixed/free rear hub, fitted with a screw-on drum brake, such as a Kuwahara.

Interesting idea...

This has the brake, but is for single speed... How about spinning on a fixed cog and using an old bb lock ring to help keep it in place? As described here https://www.sheldonbrown.com/fixed-conversion.html

It’s not perfect, and though it is sometimes called a suicide hub(!) I think that’s only where people rely solely on leg braking, with no front brake, and then the cog unscrews .

I think it would be fine if you used the brakes to control the speed and kept the top run of chain tight...

[quote][/Agreed GP5000 are wonderfully fast and supple tyres. I love them.
If you ride roads with lots of trash and flints be warned that they may not last well. I typically get around 1000 miles out of one before it gets terminally cut. For me it's a summer-only tyre. Michelin Pro4 Endurance is not quite as fast, but way tougher in


....1000 miles.. is that it? Blimey.. I suppose you would get faster at swapping tyres..

I used a kona hybrid,(the yee ha..) http://www.classickona.com/oldgold/2k/i ... -yeeha.jpg
As a tourer for years. It was great. It still is, doing service with studded tyres on winter commutes and as a proto gravel bike in summer. It’s 21 this year
It’s mtb heritage meant a sloping top tube, leaving about a foot of seat post showing. This can make it look a bit small, but it isnt.
The compact frame always made it a good load carrier, the frame being less prone to twisting forces than one with large triangles, all other things being equal. I ran it with a low rider rack and some cheap front panniers for a while, touring Spain ( via the bike bus) with my six year old on a tag along. It was always very confidence inspiring. And fun.
It feels good unloaded too.

If you want a new bike, go for it, but ones like yours have a lot going for them.

Regarding knees, I found shorter cranks, 160mm, helpful. I can’t prove that changing the cranks helped, as opposed to developing more supportive muscles in my legs, getting fitter or changing the way I pedal etc, ( or that I m not just imaging it!) but I’m am happily habituated to them now and wouldn’t go back.

Great idea! Go for it!
As for what is possible, how daft do you want to get?!
I love 24 hour or so rides (400km, 250miles)... riding all night is great fun. I ride them as Audax rides,
Google Audax UK for long distance stuff,
Or check https://yacf.co.uk/forum/index.php?board=17.0 for lots of long distance info.
Then there’s the dunwich dynamo and fnrttc (Friday night ride to the coast), though I’m sure they aren’t running at the mo.

A word of warning though... long distance riding can be strangely compelling... one minute you’re considering doing a century ride, the next you’ve signed up for https://londonedinburghlondon.com/

Good luck!

I’m currently trying a messy compromise with my Campagnolo Record and changing the grease often. That hasn’t stopped the familiar witness marks from showing up on the races.

For whatever reason, I have not had this problem to the same extent with threaded headsets. Why might that be? (I’ve had other problems with those.)

I had a similar problem with mine.. (Campagnolo record 1’’ ahead) as it was relatively expensive (previously I have tended to buy cheap steel ones for other machines) I let my lbs fit it. It was notchy within 400miles... I thought Ill of the shop at first, but their other work has been spot on, they actually have a torque meter (unlike me!) so I don’t think that was fair..
I replaced the caged bearings with loose and it was ok for a little while, but then got worse quite quickly, so I replaced with a cheaper steel one.

Blimey, 34 quid for a tyre for the turbo
Just use an old tyre (most cyclists have a few kicking about..) ...failing that, just get a cheapie like some here https://www.planetx.co.uk/c/q/wheels-an ... -and-tubes
You’ll have to do a lot of turbo training before you wear it out!

Yes, it will be fine. You may have to move the front derailleur down a smidge.

I’d stick with the 12/13 to 26 cassette. The smaller jumps between gears help to maintain a smooth cadence.

Look at the SRAM PG850 cassettes, 12-26. They’re about 100g lighter than the Shimano ones.

Rear dropout with frame no.

1930s Hobbs, accles and pollack tubing
Edit: pollock

Good question. It was on a bike that I rescued from oblivion. It’s a late 1930s Hobbs of Barbican raceweight. It’s very tatty, and had been hand painted, including over the (shot) chrome, but it is straight and not rusted through.
It’s probably one of the earliest of the marquee that’s still around, having been made in London before the blitz forced a move out of town...

I stripped it down ready for a rebuild... but that was 8 years ago now.. So I’m going to sell the frameset to help fund a new Audax frame (any collectors out there? )

I’ll post some pics on Wednesday when I’m next near the shed

Thanks for the replies, there’s no marks on the cranks that I can see anywhere.

I reckon they probably are CL, just not like the ‘normal’ round cranks.

I cleaned them up with the thought of selling them ( I want a lee cooper Audax frame...), but I think they’re rather good looking so I’ll probably hang on to them for now...
