    Default 12 speed XT and SLX

    Got the news drop today.

    Man..........cross chaining just got more extreme.

    I hope 2x never goes away, it's so much better if you actually want to use the big cogs on theses rigs, and you don't need a 50T

    That's no joke. I just installed 12sp XTR with a 34 x 10/51 and the cross chaining in the three biggest cogs bums me out. I've only got about 80 miles on it at the moment, but if you want to biff a technical climb, a quarter backpedal is all you need for the chain to drop up a gear. The instinct to move the chainring in is strong...but if you do that, the chain tries to climb up the cassette. On the other hand, the shifting is amazingly fast and quiet.

    I am happy with the switch to 1x, it is much better in rolling terrain and has enough range for big climbs but 2x is available. I wish this came out last year as I am too cheap to replace the gx eagle on my bike while it is working. I am excited for the shimano cassettes and will likely go that route on new wheels for cheaper consumable costs and probably better shifting than GX.

    On my wife's "boost" rig (11spd) I broke down the drive side 3mm spacer into three 1mm ones (wheels manufacturing) and put one on the DS and two on the NDS and it helped a lot.......and it's still a 2x.........don't have issues with 'chain climb'

    And then there is wear on the Al. plates as well.

    Sram works very well for me and I came to like gripshift so much I wouldn't go back to triggers. And I hate they choose to design their own freehub body. At least Sram had a good reason to do so when they introduced a 10t first cog first.

    Biggest benefit I see from these Shimano 12-speed groups is the Hyperglide+ cassette. I'm running 11-speed XT on my 29+ bike and clunking the chain down to smaller sprockets gets a bit annoying.

    After a couple of rides and seeing the gears I primarily use, I'll be shimming my bottom bracket over to the non-drive side. That 32X46 is a pretty ugly angle.

    Just like a Phil BB......line it up with your gears of choice.

    Not like you have a front derailleur to think about.
