PeterF Posted January 23, 2019 Posted January 23, 2019 Well then I don't really buy any reason for a 2x system anymore. Except for an oke that weighs a ton. But even then why? GX Eagle with a 32t chainring gives you almost the same top end and an easier climbing gear than most 2x setups.
Martin PJ Posted January 23, 2019 Posted January 23, 2019 My wife's bike was 1x11, I converted it to 2x11 and she is much happier. More climbing gears and also on the flats she has the 38t in the front for the district roads and down hills. One thing you cannot get away from with 1x is that those cassettes with the big gears are really expensive. Bigger gears also wear out quicker as a small chain stretch is worse over more teeth.

He needs the smallest of smallest granny on his 2x11 setup with an 11-46t cassette. But this is a very very small portion of cyclists, and of course we hope after a couple of months it's no longer necessary. I'm a 1x convert, you don't have to convince me. I was riding 1x9 with a chain guide back in 2007
PeterF Posted January 23, 2019 Posted January 23, 2019 I don't think any of the top pros use snake oil ringsCould be because a 36t oval chainring does not fit on many modern frames, and unlike most of us these guys are actually strong enough to benefit from a 36t chainring.
Martinjamessquier Posted January 23, 2019 Author Posted January 23, 2019 Won't upgrading to larger chainring require a new chain as well?Possibly I will check once installed.

Manny Fumic rides a custom 38T chain ring.Its round.surely he would have insisted on an oval since he went through all that trouble?
Allrounder Posted January 23, 2019 Posted January 23, 2019 I don't think any of the top pros use snake oil rings Froome did.... Okay it is road cycling, but still oval.

I was riding 1x9 with a chain guide back in 2007 Aaaa, and finally we find common ground .... THAT is why I am all for TESTING the gear options before spending all the money. I have SEEN people go 1x too soon .... IF they are not "fit enough" this often frustrates them. PS - I also ride 1x, and ENJOY it ! PSS - "weight" is certainly NOT the only criteria for being a "strong rider" .... I have a riding buddy that weighs in over 130kg. STRONG legs !! He can use a 1x with ease. OFTEN, it is more about the old war and rugby injuries, and buggeres knees .....
PeterF Posted January 23, 2019 Posted January 23, 2019 Froome did.... Okay it is road cycling, but still oval. I am using oval on the road bike as well, been riding oval on the mtb so long that round just feels wrong. Just waiting for my NW 50t to arrive then I will be going 1x on the road bike as well.

Just waiting for my NW 50t to arrive then I will be going 1x on the road bike as well. I tried oval on a road bike for my son who was very keen. In short, it doesn't work. Cannot stop the chain from dropping despite NW chain ring and MTB derailleur, and you miss many climbing gears. It looked cool though and he still uses it on his training bike. Would not race with this setup. The oval chain ring on the road bike is different shape to MTB oval and there does seem to be something in it. Fact that Froome and Wiggins won TDF with this is evidence enough.

Martin PJ Posted January 23, 2019 Posted January 23, 2019 Yes quite tricky to get it setup right and you sort of have to learn to shift with the oval rings. The chain would jump off the front chain ring while descending anything a bit bumpy at high speed. I thought perhaps this could be solved with a chain guide and clutch derailleur, did not try this. Ultegra make a clutch derailleur now for Cyclocross. I noticed the Aqua Blue pro team which raced last year on the 3T 1x were unhappy with their bikes.
DieselnDust Posted January 23, 2019 Posted January 23, 2019 Also tried oval on road bike. Didn't work. Expensive mistake

Sorry, I made a mistake in my post, it wasn't the oval I was complaining about, but the 1x. I think 1x on a road bike is a mistake, not oval. I certainly would like to try the Osymetric chain rings for the road bike.
