cheers folks, I'll go and see the wonderful wonky ring merchants on friday and see what I can sort.

I thinks that lot is it for the 34's until a new batch is made

may be a few 33's and 35's left after this lot of rings go.

Would one of these contraptions work, as in make any difference, with an 8-speed Alfine on a 29er?

no idea, I think young stoner has tried it with a 36 up front, he's the man to let you know if it works

john- black at the moment, but if talk nicely the the chaps I'm sure they'd send one off for anodising in a pretty colour

Genuine question - How do these work on single speed - do you have to have a chain-tensioner or a really slack chain?

distant memories...My first proper road race bike had biopace chainrings - I think it's generally agreed it was in the wrong phase on some other problem with the concept.

Black'd look a bit odd, put me down for blue if they can do it or silver if they can't.

I might have missed this earlier, but what's the biggest size?

Woudn't mind something more manageable than 48 x 16 on the road bike, but don't want to lose too much up top. One of these in 46T or 44T with 104 Bumhole would be ace.

And how eliptical are they? what's the diffence in raduis from long side to short side? I use a Paul's chainkeeper when I've got a cassette on the back. Any way that would still work?

Ta!

Right folks, I've negotiated a group buy price, there's a very limited number of 34t left so those will go to the first folks that asked about them, no issues with 33's or 35's so either MTFU or be a big wussypants on a 33. If everyone who's after one drops me an email to confirm their order and we can sort out money and delivery etc...tazwadie AT HOTmail dot com

I was quite keen until I saw the price! I know they're a limited run but it seems quite a mark up on normal rings.

i normally run Rotor Q rings on ss and XTR on gearies so it's quite a saving for me. 😀

would these work with fixed? I've got a high gear (45:15) which is fine for 95% of my commute, but then there's a killer hill at the end which I live just over the top of and I can feel the dead spots slowly breaking my hips/lungs/knees. I would guess it would only work with a tensioner which I don't want to use?

no tensioners needed squire, just a cunning set up with chain tension and yes it works on a fixie and gives a lovely smooth spin

*furrows brow and bites lip*

I guess you would just need less ellipticness/ ovality of the ring, so as to not make the slack part of the cycle too slack

Does this mean that when I singlespeeded my twenty odd year old Emmelle with the biopace chainset a few years ago, I was actually at the bleeding edge of nichedom?

Here's a question, if the chainring feels 2 teath easier (i.e. a 34 feels like a 32), do you either;

a) drop your cadence to suit
b) pedal at the same cadence but go faster
c) neither of the above, you pedal at the same cadence, with the same HR, and shift up a gear at the back, it just feels easier on steep climbs as there's less of a deadspot?

A bit of B and some of C imo.

There's no free energy available, but you do use the effort / cadence more effectively. I was on a 32/19, now a 34 oval/19 and seem to climb as 'easily' on middling / low cadence climbs ie no real difference in perceived effort, maybe more ability to avoid stalling on steep stuff considering it is a slightly higher gear; I can accelerate faster, I really notice it most out of corners or a quick spin to start a descent; spinning along the flat at a set cadence is obviously a tad faster at the same effort level ie not much. It's like an automatic very-close-ratio 2-speed imo, if that makes any sense..

Humm, I was considering one of these but can't quite decide on my gearing to match.

Im considering one of these for my cycle speedway bike, for snap out of the corners and off the start....

I'm not thinking of one of these, but I like reading about them.

I presume there's test evidence using power meters, hrm data etc to establish these do work?
