Re: Please help - tyres for 1980s Peugeot dutch style

any old 650B (26 x 1-1/2", not 26 x 1.5") tyres will do. As long as they have an ISO size marking of xx-584 where xx is a sensible tyre width in mm then they will work OK.... for example any of the tyres on this page https://www.sjscycles.co.uk/tyres-26-275-584-650b/ are nominally the cor...

Re: How to tell the width of a chain without a tool to measure it?

- I can’t find anything about the KMC 3F-2 chain (on from new) - KMC chains often have odd marks on the side plates which are (perhaps?) something to do with batch control rather than chain model. FWIW that looks like a 1/8" chain, judging by the way the rivets are set and the joining link, bu...

Re: what frame is this?

Back in the 70s a pal of mine had a Grandini frame, built by Youngs of Lewisham, with similar routing for the rear centre pull brake. It wasn't new then in fact it was his fixed wheel winter hack. nice write-up on those here; http://www.classiclightweights.co.uk/builders/youngs-builders.html but un...

Re: Help identifying and sourcing bolt

FWIW if you don't want to use threadlock, a few turns of PTFE tape can also help out fastenings like these. cheers PTFE tape is a good and quick solution, but works better on coarse threads, if the mounts are M4 the tape will mostly be displaced from the thread. Still better than nothing, though! i...

Re: Struggling with cantis

through the eyebolts i.e. sideways, not affecting the clearance to the stays

see how these brake blocks are far away from the arms?

yours need to be more like that, and the arms spread wider

Re: what frame is this?

the rear brake cable routing is to allow a nicer run to a centre-pull brake (eg mafac) provided you are happy to drill the seat pin and not move it again. I don't remember who did frames like this, someone might know or then again it might have been a later modification. The BB shell looks like a Ne...

Re: Crank Size Difference Help

some folk won't notice the difference, but I think I would.

Probably best to get a 172.5mm crankset or to think about using a power measuring hub or pedals instead.

Re: Struggling with cantis

the brake cable is not routed correctly through the 'button'; it should be hooked over the projection into the presently empty slot in the back. But don't bother with that until you have fixed the other problems. The brake blocks should not be that far through the eye bolts; the arms should be sprea...

Re: how does a pump adapter stay on?

which one? This one from SKS , is described as "unisex" and the thumblever looks as if it might act on both valves - which tempts me into thinking it might be one of these... IMHO the chuck/seal design which arguably has the best combination of simplicity, ease of use, sealing efficiency,...

Re: Miche cassette hub compatibility

…. Other hub designs would require to carry a chain-whip and cassette lockring remover, much bigger size and weight in your bag, and not something you want every day! on my touring bike I use shimano hubs. I carry cone spanners anyway, and in case of DS spoke breakage I also carry a short length of...

Re: Token Square Taper (ISO) Bottom Bracket

oddly enough I remember you posting about this and at about that time I similarly fitted a cheaper sun race BB to my hack bike. I used SFG inside it from the start, only my stuff had as many corrosion inhibitors in it as I could manage. I also fitted auxiliary seals/shields. I noted that during inst...
