Cool. Since it sounds like this weekend isn't good for Matt we'll stick with Sunday. We should start early, does meeting up at 9 or so sound good?

Update: Absent veto I'm planning to be at the parking lot on FS543 west of highway 126 at 9AM (or so) tomorrow (6/5/16). This is across the road from the USFS work station before the long climb up to the Buffalo Creek TH proper. White Tacoma, matte grey Reeb.

Maybe. There's talk of Hall/Heil but if that doesn't work out I'll let you know.

I know it's late notice, but I've rented myself an SB4.5c for the weekend, and am looking to get a ride in before I have to return it to the Golden Bike Shop at 11:00AM. Anyone have a ride planned in the morning I could join? I rode 25 miles in Waterton this morning, and loved this thing, so I'm looking to get another couple of hours in, if possible.

Ended up riding Lair, for the first time in many years. It was fine when I started about 7:40, but that trail sure gets crowded. Lots of traffic on the way back.

I did! My own ride is a 2005 575 race build, which I still love. I've been thinking of applying technology to the problems of aging and deterioration, and this was a chance to try out a modern bike to see if that was feasible. Only once or twice all weekend, and then only for a moment, did the wheels feel "big". I found it to be about as manuverable as my 575, but I'm not a great technical rider. Also, though I don't use it all that often, I need more of a granny gear than the current 10-42 1x11 setups offer. I'm guessing the 17s will offer Sram's 1x12 with the 10-50 cassette.

I'm not sure about these 1x12. I think the reason SRAM has gone totally with 1x is that they have never been any good at making front derailleurs so it's strategic move for them to sell them as antiquated.
A Shimano 2x11 with a 38/26 and a 42-11 is going to range from 18 to 100 gear inches. A SRAM 1x12 with a 28 front and 50-10 is going to range from 19 to 92 gear inches. So the range is similar, although each step is steeper.
For comparison a 3x9 using a 22/32/42 and 34-11 has a range from 20 to 110 gear inches. So its' true that the need for those miniature granny gear chainrings is no more.
The SRAM Eagle X01 groupset (cranks, cassette, derailleur, shifter, chain) weighs 1562 grams (1502 grams plus 60 grams for a BB).
The Shimano XT 2x11 groupset (cranks, cassette, derailleurs, shifters, chain) weighs 2052 grams.
Have to see how reliable it is. They made the chain even narrower, so I wonder at what point that becomes an issue.

if the pins and side plates are the same wouldn't it be capable of holding the same load?
Is the problem that it has to jump over bigger splits?

Hey Dave. I was hoping you'd chime in on this. A couple of comments:
1) It seems like there are more behind the 1x thing than just SRAM. Yeti, for example (and I have to confess to being a bit of a Yeti fanboi), isn't even putting front derailleur tabs on their new bikes. For someone like me who's coming off a 3x - or at least thinking about coming off a 3x - it does seem difficult for 1x to match the lowest gear and small steps that we're used to.
2) I don't think my aging chicken legs would be likely to break even the thinner 1x12 chain, but I can see how that might be a problem for others.

I was nervous about the 3x to 1x but I've pretty much gotten used to the 1x. I wouldn't go with a 2x at this point.
Low isn't quite as low but you could go with a 30t. I have one but i keep grinding on 32t and it's fine when i've been riding regularly. The smaller incremental steps i don't seem to miss either. You get used to it.

Don't get me wrong, I don't see a need for a front derailleur anymore. But I'm also not trying to even remotely match the range of even 2x. I'm just commenting on trying to do that with a 1x. I think the range on 50-tooth 500% drive trains may push too far. I think 2x will be a better for wide spreads is all. I did a 40 tooth giant cog on a 10 speed cassette with new derailleur cage plates. It's great at first but long term wear just isn't there and it quickly wants attention, new chain or chainring. I ended up with a stainless wolf tooth 32 because an alloy would only last 3 months.
I realize geometry has a lot to do with this, but I'm finding it very difficult to ride in the lowest gears on my 3 gear bike. It's so slow in the bottom, that steering becomes hit and miss. Catch the smallest of bumps, and you can knock off line enough that you have to foot plant. When I first started riding again this year, I was in the granny all the time, but I'm finding I don't need it as often, and I'm finding it easier to ride if I just lock the shocks and stand if I need a bit more. As some point, I'll go 1x11 or 12 just to get rid of the extra clang involved with all that extra crap for the chain to hit.
Since we were chatting Yeti, I was thinking about renting a 6 from the shop and trying it out one of these weekends. I don't think I'm ready for a 29'er, and the 6 is pretty close to the geometry of what I ride now on my 26.

There are a couple if nice 6's and a 4.5 on CL right now. Alas, for me, all are size large.
