Why aren't brands doing superboost? No one has a 32 inch wheel they are trying to carry over from an existing build. It feels like in 3 years brands will move their 32ers to superboost after realizing the extra width is needed for lateral stiffness. Or maybe not but in a couple "first rides" I've seen inadequate lateral stiffness brought up as a con for 32'ers

@pmhobson: Fair point - not sure how this scales for muddy/dusty/rainy events. Surely the numbers are more favorable towards this device. Although I'm curious to know how well the Orient works when caked in mud. Does it shift when it should? Does it not shift when it shouldn't? Also this device must be very sensitive to chainline when setting it up, and I imagine sensitive to chainstay length as well. Seems tricky. I hope they pursue it and it works well, but I'm doubtful

This is super cool. But doesn't seem worth pursuing from where I'm standing. The best aligned cog (0 mm offset) in the data loses 6.89 watts. Relative to this baseline, the two worst aligned cogs lose 2.95 and 0.54 watts. Across the entire cassette, the average loss relative to the most efficient cog is 0.9 watts. So at best you can save an average of 0.9 watts across the cassette. But it's not that simple First, the cross chaining is only one of the factors affecting the losses - the other is that smaller cogs are less efficient, hence the smaller cog having worse efficiency than the largest cog despite the exact same offset (19.5 mm). Second, the new 'two chainring' setup still has cross chaining - just less, so it won't claw back all of the losses. Third, more time is spent in the middle of the cassette than at either end. You're gaining efficiency in the cogs that don't see as much use. To be fair, these are the numbers for an 11 speed setup, and I'm sure the losses are larger on a 12 speed setup. But a ~1 watt gains for something that adds this amount of weight and complexity seems like a hard sell, especially if it requires a different frame, and introduces the risk of the chain coming off during hard efforts.

@onemanarmy: great I was getting super bored of the stuff that's there now and will totally be able to ride the stuff they build for rampage

Depending on whether you roll it vertically or in line with the head angle, a 60mm rise bar either lengthens the effective stem length or shortens the reach of the bike, it's not some magic solution that increases stack while keeping everything else the same

Surprised they didn't go superboost. It's not like anyone has a 148 boost 32 inch wheel laying around they want to be able to swap over. Seems like 157 makes sense if you're starting with a clean slate

@Lostrodamus: "we have Mike Levy at home"

Didn't some rando ride his line after the event? And during the event Brendog said none of the other competitors would be able to ride his line, which is clearly bs because some rando rode it two weeks later?

@DoubleCrownAddict: thanks for sharing. This rapey image made me rule them out instantly: https://www.pinkbike.com/photo/20058412/ No YT for me

@Jprestidge: 5 years ago the full 29ers were quicker... than the 27.5 bikes at the time. Not many folks were testing mullets at the time. Which now seems to be the go to. So it went full 27.5 > full 29 > mullet. Or at least that is how I remember things
