29er 1x10 question

i'm guessing a few of you have 29ers with 1x10 set ups. my current 29er is still 2x10 with the smallest cog being a 22 (with 36 being largest on back as per normal). i'm in this combination for maybe 10% of any given ride, give or take. at times i really feel like i need this gearing.

i'm thinking of a new frame, which would be dedicated 1x. the std set up seems to be 30 on the front and 42 back. checked it out on bikecalc.com and i might have to really HTFU to run this combo…

22x36=17.7 gear inches vs 30x42=20.7

anyone go from one to the other and is it much of a diff? i'm thinking those 3 inches might be substantial on a long ride. guess i could go girlyman and run a 28, aye carumba… (28x42=19.5)

If you are really worried about the lost gearing, leave your granny on your crank, and pull the chain over manually when you are really feeling the need. After you've gone ~10 rides without ever using it, you can pull it off (or just leave it, wth)

Yeah, entering 2nd season running 1x10. Came from a 3x 10 (I know who runs. Triple on the shore). I was running a 24-32-42 and 11-36. I am so pleased with the 1by. I think I lost 1/2 a pound, do not drop chains with NarrowWide chainring, simplified shifting pattern, and a better location for my reverb control. I will never go back. I can tell you I do not have the same range, but my body has compensated by becoming stronger / faster. I went from 0.66 to 0.76, effectively losing my easiest gear. Hasn't bothered me. If you absolutely need the 0.61, you may not have a choice, otherwise hit the 28 NW and enjoy 0.66.

This is what I do on my 650Ber… and I have yet to use the granny, but I know the time will come and I`ll be more than happy to drop it down by hand.

I am running 30x42 on my E29 and it's plenty low enough.

If you can't push a 30 X 42 up your hills it's time to quit riding and take up tiddly winks or lawn bowling.

Seriously though the higher gearing can be tough at first but you adapt to certain extent and chage your techniques a bit. Be honest with yourself though. If you know you can't push the harder gears don't go that way.

Debate? Bikes are made for riding not pushing.

Same here. I wish I had 32 up front because 30x42 is actually too low 98% of the time. I think 32x42 would be a better as a low. Any lower is just spinning.

Agree. When my current drivetrain wears out I'm going to try a 40t rear cog instead. I don't really need the 42 and it will make for a smoother transition off the 36.

i've given up being so stubborn and put a 28T on my 29er hardtail, replacing a 32. rear is 11-42. got tired of grinding away up the nasty climbs in whistler/pemby. i know its not cool but i love it, much easier spinning up long steep climbs, and the only place i spin out is on paved roads going downhill, a non-issue for me. my riding buddies are all running 28's too.

i see the OP is from comox, in which case a 32 would work well, much nicer climbs there!

Was just about to say: I know lots of Whistler guys that run a 28 front on their 29ers. Nasty climbs in the valley…

I run a 32-42 on the shore and don't find myself running out of gears. There aren't too many long steep climbs here that I feel the need to go lower.

I did put the granny back on for Nimby but have not used it in the year that it has been there. I was bonking way before the gearing was an issue…

Don't be a afraid to throw the 28t on and possibly bump to a 30t as you get fitter during the year. Anyone that gives you grief about gearing that you choose obviously doesn't know your riding location, riding style, size, fitness level and cadence preference.

I have a 30x42 on my Nomad and would definitely go 28x42 on a 29er given the trails that I ride. I'm not a good climber but I can push the bigger gears if I need to. I just don't want to push the big gears when I can be spinning away and I like to have the easier gears when I'm doing laps of Fromme and Seymour. Pretty simple really. Go for it.

29er HT running 30x36 for shore xc. My goal was to build as light as possible (22 lb) to make up for beer weight.

30 NW x 36T is a hard peddle up old buck (i make it 10% of the time, and usually walk the steepest parts), but for lower seymour peddling its perfect. Ive been contemplating 40T for spinning up Fromme and old buck, but cant justify the expense to benefit. Peddling up mtn hwy is fine although slow. The tougher gearing forces me to peddle harder to keep the wheels spinning.

What are you trying to sell here?

Everyone knows a 29er sucks for freeriding.

i got spooked by a comment drewm made about the 40/42 tooth rings wearing super fast, and as a result i end up using mine as little as possible. i find i spend the vast majority of my climbing time in the 30x36 combination, and save the 40 for when the pitch is steep and sustained, or i'm really gassed. there was a learning/fitness/comfort curve for sure, but it's pretty natural now; i guess my conception of what constitutes my "bailout gear" has simply shifted to adjust to the gearing currently available
