Allrounder Posted January 22, 2019 Posted January 22, 2019 one of my mates went from a 32 to a 34 csixx. He claims that is the best decision he made apart from buying the bike.
thisismyotherbike Posted January 22, 2019 Posted January 22, 2019 Won't upgrading to larger chainring require a new chain as well?
Grease_Monkey Posted January 22, 2019 Posted January 22, 2019 Won't upgrading to larger chainring require a new chain as well?Depends on how long your chain is. Generally speaking going 2t up most people are safe, 4t up and you will need a new chain. But it really depends...
DieselnDust Posted January 22, 2019 Posted January 22, 2019 Won't upgrading to larger chainring require a new chain as well?It depends. How much slack is taken up with the b tension screw?As mentioned, chain length?
stefmeister Posted January 22, 2019 Posted January 22, 2019 With only 200km one have to wonder to what extent you have pushed your limits on longer and steaper rides ..... Granted, we have no idea of your typical trail. Around here there are just way too many hills. After a few hours in the saddle, a 50 and 34 and a steep incline may just be nasty combination .... Should you go this route - Evobikes has a wide range of chain rings, both standard and oval.No man. Eagle is a waste of extra weight if you’re not running at least a 34T chainring. 36T should be standard, and Same ratio as 30T on 10-42 cassette.

He was riding something like the 38 or 40 at the back !! DAMN he has some STRONG legs !!!! I am repeating myself here .... the 1x system is surely the answer for STRONG and experienced riders. BUT, there are way to many "weekend riders", ie ex golfers, now buying bikes with 1x, just because it is the cool thing, and then they cant climb and they spin out on the flats .... I would seriously recommend people to take a 3x bike, ride an hour then do a proper climb and CHECK which gear you "need" to get up there. Now you know the "Ratio" that works for YOUR legs - granted this really should get better as your fitness improves ... but without the right gears you walk too many hills and give up before gaining the fitness ..... Next test - CHECK what speeds you do on the flats, and on the tar section to and from the trails .... check these ratios against your 1x options. Frankly, many really should be riding 2x .... not too worry, as soon as everybody is on a 1x, the industry will magically discover their is market for 2x and everybody will have to upgrade again ....

I don't agree at all. I weigh more than 100kg, been riding 1x for a while (+/- 3 years). My power to weight ratio is quite low, I really don't struggle up any hill (my normal spots are Jonkers and Helderberg), and I don't spin out on flats either. My wife, as awesome as she is, produces next to no power on a bike (rides maybe once a month), and she is just fine with 1x11 - enough gearing to make it up to saaltjie in Jonkers, and she also does not spin out on flats. If you are running out of gears on a 1x12 system on either end of the spectrum you either have the wrong soze chainring or you're so unfit you're about to have a heart attack at any moment. The only reasoning I still buy and understand for 2x systems is to have smaller jumps between gears - guys that spend alot of time grinding out long km's and want to find that sweet tempo spot often need those small jumps in gearing.

There are enough threads about chain ring size to indicate this is not a simple one size fits all topic ..... What I was TRYING to say in my post : "TEST your individual limits, both in climbing and top end for where you ride" Record those ratios, then check if a 1x11 or 1x12 fits your requirements. At the moment I am happy with my 1x12. I am running a small ring up front. I need the granny ... I dont spin out on the trails. On the tar sections to the trails I can ride at 40km/h, even got it over 50km/h down a hill spinning like crazy .... for ME that is fine. I appreciate the next rider will have better knees, and different needs. BY TESTING their own limits they can KNOW what they will get before putting money on the table.
OnTheRicky Posted January 22, 2019 Posted January 22, 2019 What is the general consensus on SRAMs X-Synx 2 chainring teeth design vs other brands that have normal teeth? I'd also like to upgrade to an oval chainring, but in my mind, it feels like a downgrade if I don't get the SRAM oval chainring

DieselnDust Posted January 23, 2019 Posted January 23, 2019 Correct. The 11s cassette has a 42 joined onto a 10s and the 12s is a 11s with a 50. Most people have the perception that the 2x system allows for smaller steps because there's a few gears in between but it's not really the case since a 2x11 only offers 13 distinctly different ratios so 1 more tha than a 1x12
Martin PJ Posted January 23, 2019 Posted January 23, 2019 Done a quick search on pictures of Yolanda Neff and Nino Schurter's bikes, they don't appear to use oval chain rings. I have gone back to a round chain ring. I don't think it makes any difference.
DieselnDust Posted January 23, 2019 Posted January 23, 2019 I don't think any of the top pros use snake oil rings
Grease_Monkey Posted January 23, 2019 Posted January 23, 2019 Correct. The 11s cassette has a 42 joined onto a 10s and the 12s is a 11s with a 50.

Except for an oke that weighs a ton.
Grease_Monkey Posted January 23, 2019 Posted January 23, 2019 now if only it was as simple as that .... It is... bicycle gear ratios are not rocket science.
