So, I've been looking for some rings to do a double chainring setup on a Raceface triple crank. The idea is to have a little but not tiny small ring for going up stuff and a middling to large big ring for going along and down. The little ring will be mounted on the granny ring position on the crank, the larger on the middle ring position. The BCD measurements on the crank are your (old) standard 104/64 stuff, it's all non-boost.
Anyway, I found this on Wiggle

The only ratios available are 39/26, which is perfect to be honest, but it says 'with spider'. I assume I can just take the spider off and use them as boggo chainrings? And the chainline etc will be fine? Anything else I've been obviously thick about?

This is genius. It's a wonder no-one thought of it before.
Those rings look like they should be fine, difficult to be sure that they don't have some weird bolt pattern or something hidden under the spider but at that price give it a go. Worst thing happens is you post them back.
(as an aside, who wants a double, on an e bike, in tiny ring sizes? I guess no one hence £24)

I know, right? You could, thinking about it, even have a tiny ring for really steep stuff, a middle ring for normal along stuff and then a big ring for downhill stuff. It's obvious when you think about it...

An excellent point

Given the discount being applied, no-one 🙂
Sorry seems I cross edited that to add I guess no one hence £24
