I’m about to buy some new cranks, but I can’t find an oval chainring in the size I want… I can get normal round though..

I’ve had oval for about 6 months and don’t think I noticed a difference, so if I change back will I die?

Anyone else done this and managed to escape Death?

Nope. Changed 32:19 oval SS to 38:17 round for a race. Died in a very metaphorical sense, lost 100 places in a lap. Awful. Then I put the oval back on and snapped 3 ligaments in my shoulder. Just had reconstructive surgery and I’m off the bike for another 2 or 3 months.

Hope this helps.

So, what your’re saying is… Go back to round, ok as long as I don’t mind losing a place or 2…… but don’t even think about returning to oval or the bike will bite me..? 😯

Hell hath no fury like a chainring shape scorned.

Effect of removal is the reverse of installation.

Changed 32:19 oval SS to 38:17

I think, being a super sleuth … The ratio change was the cause of metaphorical death, irrespective of the shape of your ring ….

shape of your ring ….

He he. 😯

Ha! It was for Battle on the Beach. Gear was good, but I went too hard on the first lap and blew up

Thought this was going to be about the London Road seat tubes, disappointed! 😆

Phil, are you under 20 and over 12 years old ?
Thinking of changing from a round chain ring?
Like a warm drink and a biscuit in the evening?

Could I suggest Ovaltine ?
