ALL SOLD
New Sugino 49t 130mm BCD very likely track or single speed as no ramsp/pins but I've used one on a triple 9 speed set up. NOS TA(Mavic 631?) 38t 74mm bcd TA duralumin rings 3 x50t & 1x51t all 6 arm/bolt fixing
They've been stored for quite some time so have minor marks on the outer surface however of the 50t rings, 1 looks to have never been used as the metal is fresh & untouched in the teeth, the 2nd has maybe had a chain round it for a few miles the 3rd has been used a bit more but is still in hardly worn. The 51t also has signs of use but is hardly worn. Close ups show everything in terms of wear to teeth.
£9 each for the 2 new/newish 50t ones including postage, £7 for the more used 50/51t rings.

I know it's a bad habit, but...

The triplizer is actually a Stronglight Speedlight (you need cranks with no locating lug on the spider for a second ring), and the two big 74mm bcd rings are (I'm pretty sure) for a Mavic 631 triple...

Nice gear.

Correct on the tripleiser, got the TA streak in my head have now changed that,
I was going to use it with an old Thun Aero Coronado chainset, to have a 52/42/36 set up that was still lighter than my DA triple but change of plans and all that.
The 38/36t rings were sold to me by a shop saying they were TA...so I went with that. As far as I'm aware they'll fit any 74mm BCD.
thanks

Here you go:

I've got the same adapter, that came with a 38t ring like yours, sitting on my desk right now. I've also seen them sold (mistakenly, I'm pretty sure) as TA, and it may be that TA made them for Mavic (I know Mavic often used subcontractors) but they're certainly made to fit that Mavic crank. They actually have a nicer finish than contemporary TA-branded rings: the TA rings are left rough on the inner faces, while the Mavics are shiny shiny.

thanks in any case

No worries.

would that Sugino 34T be for a middle ring of a triple? Or is supposed to run on its own?

It doesn't have any ramps or pins so in theory could run either on its own or as a middle ring for a triple or as i'd intended it a small inner ona compact.

Could be interested in the old style TA rings as I should be getting some soon from a mate but not sure what sizes they are, hopefully with the adaptor as well.

I don't suppose you have the correct TA fixing bolts to go with them have you?

I've just got a pair of TA 5-pin square taper cranks that they're to go on.
