[Closed] Elliptical single speed chainrings

Do they come with a stick on beard and a pair of sandles?

Apparently it was this bloke who invented them. He realised they carried more power when thrown if they were oval shaped. He discovered this after making a batch of pizza bases after he'd drunk 10 pints of lambic ale!

yes but they sandals have go faster stripes on them as you'll be quickerer than any other beardy nichewhore 😆

I used mine for the first time today and I found it utter codshite. No-one else get one.

(gone +2T on the front compared to my round ring and didn't notice any difference apart from going faster for the same effort - which is good right?)

is the aim to give you more excuses for rests cos you have to keep stopping to put the chain back on?

never dropped a chain with one yet.

you do need to know how to set them up . The special taz instructions I supplied to some new users were rather good though 😆

these rings of wonkyness are clearly intended for attention seeking buffoons,and after buying two,I can confidently state that they don't work at all. my chain never falls off,and I no longer have an excuse to stop halfway up a hill.
I have contacted the Electricity board.

yes,but now my bottom hurts.

yes, but to be fair keef. It did clearly say that you needed a 104 BCD ( I didn't expect you to take that as Bumhole Circle Diameter)

How did you stretch it that far, did you get fingered by an elephant?

Taz,my Elephant has no fingers..........

and can I have him back pls.

Oi Keef

forgot to mention I do have an 80mm 26" rim, drilled out to very light if you needed it

I did a little experimentation with oval rings on suspension bikes, back in the day when pivots were high and shocks platformless.

Worked really well. Evened out power, stopped bobbing.

they're great on a fat bike as well Brant 😀

Will they solve the world's energy supply problems?

n,o but they do make you more attractive.

and come with a free roll of carbon fibre and spoon for emergency bodge repairs, cynical-Al

do they do em for WI cranks ?

Thank you Mr Tazzy for advertising your fabulous magical rings again. They are wonderful. Please may I order 11 of your 32T and 17, 37t. I want to sell them on my stall at the circus for £50 each and make a killing. I is an entrepreneur init.

Biggest load of old tosh I've ever bought into. 😉

I only went up one tooth but reckon I could have gone two.
Any plans stainless ones Tazz ? I reckon a Ti would be out of my meagre budget.

sofaking- it's something they may look at, I have a proto direct mount middleburn uno one and I've got WI crank to take to them so they can have a look at doing one for me.

Swede you've already had a go on my "magical ring" and sold it to others......It came back all worn and out of shape and in need of a good lube.I've still not seen my share of the proceeds either!

Takisawa2- no idea on the stainless front, rather fancy a Ti one so hopefully they'll do a couple for me.

I saw something bonkers on the Leonardi stand at Bespoked Bristol today.. Adjustable sort of elliptical chainrings. Wish I took a picture to show, but basically, they were half round split rings, that you could adjust outward to give you a greater degree of oblongness, in one tooth steps. The more you adjusted them out, the longer the flat section without any teeth. Couldn't see any real world purpose for them, but was impressed with their bonkersness anyway!

I like them. That's all. Apart from, stainless or some other steel option would be good.

I'm already too fast on my SS so won't bother,but thanks all the same.......

if enough folks are interested, i'll have a chat to kev and see if I can get you lot a bit of a group deal thingymebobins

102bcd????

If there as shite and gimicky and useless as you say i'll have a 33 tooth please.

you already got my email Tazz

I'd be after one, 33t, my SS isn't looking niche enough anymore

right 3x 33t rings, anyone for anymore I'll go and see them at the end of the week

I'd like a 34 please, i did e-mail you.

is one o them 33's mine?, if not that'll be what i'd like ta

sorry mark, I missed that 😳

yes it is Mr Dog

Put me down for a steel one if it ever happens..

now that its sping and I have shaved my beard, I need somthing else to make me stand out as a nichemonger. Therefore a 33t would be right up my street too!

if all the 33Toothers are using 32's at the moment I'd really say go to a 34 as 2T up seems to be the optimum increase for the same perceived effort on climbs.

Hey Tazzy, how do I contact you to order one too? You don't seem to have an e-mail address in your profile.

peanut, let me know what size your after, and i'll add it to the shopping list. I'll go and see the chaps and see if I can get you a bit of money off and a contact/email ref that'll sort it out and you chaps can organise it direct with the shop.

as I said I'm nowt to do with 'em I just damage their reputation 😆

Mr T, put me down for another 34 if there's more on the way? Ta.

Cheers tazzy, guess I'd go for a 34t 104bcd.

good advice on the 34T, lets go for that in a 104bcd as well. cheers!

I'll stick with the 33T please.

Should be more than enough with an 11T on the rear. 😆

When are the burn friendly ones ready???\

By the way Hanny tomorrow is a yes- my battery has died on the phone!!

They do work, and here's why: http://www.highpath.net/highpath/cycles/ovals/01.html#how

However, in my experience of using them on a singlespeed, they are not great for this application: a smaller round ring would be better. For multiple rear cogs, they will get you through the dead spots better, and give you an edge when technical climbing. They feel weird for all of about five minutes, after which round rings feel odd and 'dead' like Biopace.

Unfortunately, Chris Bell is not making them any more, so I've been looking for another source.

@tazzymtb: Are Goldtec still making them, and would they be willing to make custom ones do you know?

Doctor Rad, yes they're still doing them, what's left at the moment in the remainder of the first production run.

they'll do custom orders, but it takes a while for a space on the CNC machines (still waiting on some custom fat hubs)

they are tops on a singlespeed as folk like john mylne and ned overend use rotor Q rings for SS race applications. The goldtec ones are even more wonkey and seem to suit SS applications better ( I have both)

Kev at goldtec is ya man for email enquiries

Thanks for the info. Personally, I didn't get on with them on SS, but then I never really got on with the entire SS format when living anywhere other than the flatlands of Cambridge...

How long have you been waiting for your hubs?
