So who's going to post the two Trek 32" bikes from the B2B site?

Sorry, I must be high. I saw Post Mount but read Flat Mount, which is specced on the current gen Lux World Cup frame. I agree, Post Mount is appropriate here. I'm stoked now to realize that Canyon has moved away from Flat mount on this bike.

It's a shame there is no way to adjust the height of your handlebars.If you bike's stack is 10mm lower than you'd like you just have to put up with it.It's really unfortunate.

I could give this a go, would back to back race sim laps be enough to provide accurate results? At least in a way that it is consistently one way or the other?

Let me say more clearly what was implied in my previous post: those old road bike rolling resistance tests tell me that our own internal rolling resistance gauges in our brains are not very trustworthy. I'm not convinced that radial tires roll slower because the only evidence we have is that they feel like they roll slower. 21mm tires pumped up to 120 psi feel fast as hell on asphalt. As you go faster, you get more and more vibration feedback from the tire, giving the sensation of greater and greater speed. A 32mm tubeless GP5000 pumped up to 60...

Slow clap. Part of the reason why road bikes came with 19-23mm tires pumped up to 120+ psi is because they felt faster than bigger or softer tires, and because of flawed test methodology (testing tires on smooth steel drums in a lab vs. testing on real asphalt). I've heard a lot of people in the tire forum say that radials roll slower, and they certainly might. But until I see actual test results using a methodology that makes sense, I'm going to assume that no one knows the answer to that question.

Personally I'd rather have this thread be quieter than be completely overtaken by ebike tech.

All this drivetrain efficiency/Gearbox discussion is making me think about the joy I get from riding my singlespeed.

"Among the highlights of the collection are the Centric RC MIPS and Cadence RC MIPS helmets, two models already established within the SCOTT range but updated to remain the brand's reference for competitive use. Both models feature the MIPS protection system, designed to reduce the rotational forces transmitted to the brain during oblique impacts. They also include a specific goggle holder (Centric RC only) and features designed to maximize aerodynamic performance."

my attempt at a palete cleanser to get this forum back on track. Scott XC team is wearing some new interesting looking helmets. Caught my eye is this weekend. Is the black piece another attempt at the canyon breakaway helmet, is it just a fancy sunglass holder, maybe aero? Couldn't find a great photo but its odd looking.

I don't think most people articulate why they dismiss gearboxes very well, or at all haha. For me, I'm not too interested in them for a couple of reasons. Firstly, I don't have the issues with derailleurs that others seem to have, I don't smash them or snag them on rocks, and I race DH and enduro in Utah and Colorado so there are plenty of opportunities for me to do so. Secondly, I like mechanical drivetrains and don't like grip shifts. Unless I have missed something, all mechanical Gear boxes have to use a grip shift to pull cables...

I think part of the problem is that "MTB" covers a really diverse range of riding styles, and for the different styles, a variety of engineering requirements and interests. It's easy for people (myself included) to only consider the style(s) of riding they do when they promote or bash posts. I agree that there might be interesting trickle-down technology from the latest "moped" innovations in MGUs for predominantly gravity-driven forms of pedal MTBs. While the idea of a gearbox that is comparable in weight in efficiency to a conventional 1X drive train is exciting, from the engineering side of things...

That’s as safe as betting that the Tech Rumors thread will be derailed in the next half hour.

As though the the gearbox wasn't also invented in the 1800s... Feel free to hate the lightest, simplest, most serviceable, most efficient method of changing gears on a bicycle that humanity has invented so far, but the rest of us will accept derailleurs where they make sense.

Shut the fuck up about drivetrain efficiency. Holy shit. Go find a different thread.

I typically use the climb switch once per ride. I like to turn it on halfway up the climb when I remember I have it and might as well use it. I tend to turn it off halfway down the descent when I’m puzzling over why my suspension isn’t working. I suspect I am not in the minority.
