Chainsets for old legs

[bagpuss]

Apart from used TA only a limited choice seems available.
Looking for square taper .
Sun xcd did made some nice 5 pin TA compatible ones a while back. I cannot find them any longer
Ideally 44/34 or smaller rings .Spa cycles sell some double touring ones that may do the job .

Anyone seen, bought anything else that may be suitable.

Stronglight 49D fit on modern Shimano square tapers. They have 50.4mm bcd so you can put pretty much any size chainring on them. I have 48/28 on one set and 54/46 on the other. Both have TA rings. Watch out because they come in both English and French pedal threads!

I was going to suggest Spa cycles, then read your post more carefully...

If you can find the cranks then 86 BCD rings are fairly widely available, they go down to 26 tooth (IIRC) and up to 50+ all on the same BCD, you can run one, two, or three rings with the right bolts and spacers and BB on the same cranks.

I have a saved search for SR Apex cranks, which came with a 94 bcd (amongst others).

I'm running Stronglight 49D 52/36 on the front on a Tange Seiki LN-3922 square taper spindle.
SunTour New Winner ultra-6 13-15-17-19-24-32 on the back - in 120 dropout.
SunTour Cyclone derailleurs front and back, GT on the back for 35 wrap.

Stronglight 49D is a very good 5 pin and the rings are TA Cyclotouriste which you can still get new: https://www.veloduo.co.uk/products/...50-4mm-80mm-pcd-alloy-chain-rings-inner-outer.
TA Cyclotouriste rings come in outer: 52-40 + inner: 42-26

Gives me 52/13 for downhill or flat and 36/32 for hills which is pretty low.

Sugino XD will do the job in double or triple. I have a spare triple set you can have for £20 shipped
