29er 1x10 question

My first drivetrain set up this way is about to wear out. OneUp 42t and 16t cogs on an SLX cassette, RF NW 30t ring up front.

I'm thinking of going Absolute Black for the next. 40t cog in back because I don't really need that extra low gear and I think it'll shift better with a smaller jump from the 36t. AB also makes a 13t lockring so I could lose the 11t and not have to split the carrier. Also I want to try their 32t oval ring … because it's an interesting idea. Anyone tried any of the AB stuff?

There's nothing better than an Orangina after cheating death with Digger.

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 had a similar thought but fixed the issue by going 26t ring up front [HTML_REMOVED] a return to 11-36 on the back. Everything is lighter - shorter chain, no 100g+ extra on my cassette, lighter ring and the climbing is fine for 95% of what I do. For Windy Pass and the like, I may put the 40t back on, but otherwise my Surface will stay with the 11-36 gearing via Cinch NW 26t ring.

Does anyone else other than Race Face or SRAM make a direct mount crank? I am guessing not and I can't get on with my work with out knowing the answer….

Hope?

Debate? Bikes are made for riding not pushing.

I need three prices before I can get sign off from the purchasing dept!

Hope?

Yep. And doesn't E13 as well?

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!

Agree with Clark, I switched to a 28t before the Chromag death ride last summer and very happy I did. 30t usually works for riding in the North Shore, Squamish and Sunshine Coast, but for steep techy climbing the 28t is fitted. The nice thing with direct mount rings is that it is quick to make a switch.

This is a good point and as far as I know E13 and Hope are the only other two options. It isn't like the good old days when there were a bunch of cool aftermarket bling cranks to choose from.

PB says the Praxis 11-40 cassette will cost $130 and weigh as much as an XT cassette. If it shifts well this might be a great solution. For slightly more than an OneUp 42t cog you can get a complete cassette for half the price of an XTR 11-speed and you don't need a new shifter.

Still aluminum (aka fast wearing) and still heavy. Only reason to go 40 or 42 is because you're stuck with 4 bolts cranks. DM rings allow for cheap cassettes, shorter chains and less weight. Now that Turbine Cinch is out and there is still X9, you don't need carbon price to go direct mount ring.

this guy Lee did a good job of getting into this question here:

Is there a compelling reason not to go 26t DM on the front and a 10spd 11-36 out back? Seems there would be a risk of spinning out on the road but the low gear would be comparable to a 30x42. Then you get the bonus of lighter weight across the board.

the first one that springs to mind is that many suspension designs are optimized around a specific chainline, and thus chain rings of a certain size. designs that feature / rely on significant amounts of anti-squat - so, norco's ART or banshee's KS link, for instance - produce more pedal feedback and are less efficient when the chainline is out of their comfort zone
