    1x drivetrain crew--what size is your chainring?

    Just curious what other people out there are riding on their trail/AM bikes.

    I had a 30T and just swapped to a 28T but haven't ridden it yet. I find myself at least once per ride wishing I had one more easier gear but unless I'm on pavement going towards the trail, I've never wished I had higher gearing.

    30t with 11-42 10 speed. Might be able to use a 32 but there are certain climbs where it would be tough.

    Where did you get the 28T?

    28 tooth front, 42 tooth rear on 1x11 with a next SL crank. I'm often above 9000 feet and climbing steep stuff, so the 30 tooth is just a bit too much for me. It's the same ratio as a 24 front, 36 rear.

    XX1 and Next SL both have 28 tooth options. XO1 does not.

    I think wheel size should be mentioned, AM rides can easily be any of the 3 major sizes. Still in the air on 1x10, been trying to ride my 2x10 setup as a 1x with 33 front. I'm thinking 30 with 11-36 will be my choice for my 27.5 on my terrain, the front could easily change depending on where I go.

    1x drivetrain crew--what size is your chainring?

    Wheel size is relevant as well as where you ride and what type of riding.

    I ride 27.5 in southern New England. Tech with lots of short climbs. I run 32 front 10-42 rear. Ratios are perfect for me. I can climb anything around here and only spin out on the road.

    30t, but that's mainly because I was using an ultegra cassette. A 32 would probably be a little better for me now.

    I've been toying around with different size chain rings and cassettes lately. On my 29er I'm running a 32t with a 12-36 10 speed cassette. This setup seems to suit the big wheels well, I can climb up about anything with a bit of momentum.

    On my 26er I just put a 30t paired with an 11-34 9 speed cassette. The smaller wheels don't climb as well so I hope the 30t ring will get it up the steep hills.

    some good setups VT, my 22/32 with 11/34 works great however if i went 1x i suspect a 30t would be my choice as well.

    Thanks man, if you do ever go 1x, I recommend the Race Face narrow/wide 30t - it fits a standard 104 BCD cranks the easiest.

    28t with 10-42. That is for 29-er, for 26 inch wheel I would stay with 30t ring.

    32t with 11-34 9speed on 26" wheels riding the western slope of Colorado. I find I gas out too soon on some trails so I'm gonna try a 30t NW with a 12-36 cassette.

    32t pushing 11-34 9spd on both my bikes.

    I used to push a 36t chain ring but a combination of injury and overly long downtime has de-powered me this year.

    32t 1x10 on a Race Face Turbine crank, 26x4 fatbike at 11-42t with a Wolftooth Giant Cog & 11-36 an a 29er wheel set. At first, the 32t was not low enough, but after 3 months & about 600 miles of riding, I rarely get into the 36t cog on climbs, let alone the 42t bailout gear.

    32t driving an 11-36 cassette on a 26er. Techy trails with lots of steep ups and downs. Occasionally I would like one easier gear so I'm likely to stick a 40 or 42t cog on my cassette in the near future. I only spin it out on fire roads. I certainly never go fast enough for it to be an issue on any local singletrack.

    28t on a xo1 29er. Geared specifically for 24% tech climb that is part of my local loop. Sacrificed a lot of top end

    Yes. Again, 36 tooth with a 11-36 ten speed rear. On an Anthem 29er. I weight ~220 without my pack on.

    Cool. 235-240 here and 30T is fine for most but I'm going to leave the 28T up there for now. I have an 11-36 cassette. If I had a 10-42 cassette I'd be fine with 30 or 32T

    32t up front with 11-36 on a Yeti 29r in Northern Utah.

    I do 2,000 - 3,000+ feet of climbing per ride on average. Some climbs have felt fairly stiff with the somewhat-limited gearing, but no major issues so far.

    Our stiffer, high-elevation riding is about 95% open now so I'm now dropping down to a 30t up front. I will eventually add the 42t in back if I feel it is necessary after installing the 30t up front.

    2x10 is the new 1x11! Great range with 24/38 to 11/40 WT. Shimano drive train w/ clutch RD is super smooth and quiet. Perfect geezer gearing on my Carbine 29 for the long summer alpine climbs to 12k and I love cranking the big gears on the way down.
    Don't think I could live with the 1by. Sorry if this post would be better on another thread.

    I never run outta high gear if I run 28T and I have 10-42 cassette. The trails I've been riding are slow and super techy.

    I think 1x is the new 2x10. The only problem I've had is mud. We had a crazy wet spring in MD. The total opposite of where I'm at now.

    I think you'd be surprised how well you can do with less. I thought I was struggle with a 32t / 11-36 living where I do (Utah), but so far, I'm just proving to myself that I can push harder than I thought I could. I DO want a bit more range with the 42t in back, but so far, I'm pumped with the 1x.

    Usually 34t with 11-36, bit tough on some climbs around where I ride.
    Updated to 30t with 11-36 for steeper climbs, seems too easy now compared to 34t.
    Might try 32t instead.
    on 27.5.

    Running a 32 on my Superfly and Fuel EX, going to a 34 on on my Yeti SB-66 when I build it up. The 32 does a good job on the Superfly, not so much the up gearing from the larger wheels, more just that the Fuel EX attacks things a bit more aggressively so I can find myself spinning out when I've got a bit of a gravity advantage.

    My Butcher is 32 / 11-36 with 26" wheels. I've considered swapping for a 34 as I spin out more often than I use the big cog, but it's nice to have the bail out gear.
