just checking your cred. not convinced. you do you.
Youāre obsessed. Cute.
I also think 2.2 max clearance on a modern xc bike is pretty silly. There isnāt any reason I can think of to not allow clearance for at least 2.4 or 2.6.

From a sales/marketing standpoint, it definitely seems that not being able to accommodate 2.4s would be seen as a negative by a lot of prospective customers. Having flexibility and options is key.
On the weekend I was listening to an interview with Rose Grant. Sheās been running 2.4 Aspens all season on her XC bikes, but did go down to 2.25 Aspens for Leadville. However for Breck Epic she went back to 2.4s. Definitely a trend towards bigger tires for XC events. Doesnāt mean you have to run them, but options are good.
Iām taking my SC to Brown County, IN this weekend with the 2.35 Schwalbeās on it. I think those will be a great fit for the heavily rooted, at times rocky, terrain there.

Yeah, crazy to limit to 2.2 this day and age. 2.2 would be pretty limiting on some of the rooty areas of the world.
Note the very best XCO riders in the world almost all had droppers and decent tyres for Snowshoe. Not an overly technical race compared to most the circuit this year.

Has anyone actually measured the 2.2s on the SC? They might actually be wider on the 30ID rims?

Thats a good point. My most recent 2.35 Ikon measured closer to 2.25 on an 25ID rim.
Can I hear a couple of height/inseam measurements and what size supercaliber your riding?
Im 5ā11" with a 31-32" inseam. Iāve always ridden Mās in most brands. Trekās site says im a M/L and the guys at the Trek store were fairly adamant that I should be a L. Iād obviously lean towards their recco but im still having a bit of a tough time pulling the trigger on a Large 
Iām in the same boat as you. Iād probably go up to an L. Interestingly I was just rewatching the pinkbike group test review this morning and Sarah Moore talked about sizing up a bit in the video.

FWIW, im 186cm, 80kg. 81cm inseam. 715mm saddle rail height. 720mm bars with 16 degrees of sweep (which takes 10-15mm reach away c/f ~9 deg bars) i like my dirt bikes a little small and like longer stems. i run a large with an 80mm -17 stem and itās perfect for me. if youāre into more conventional fit and/or shorter stems, definitely go large. the XL to me felt like steering a truck, but the large is just right. the large will not be too big for you unless you insist on an 80mm+ stem.
sarah moore is an accomplished rider, but her fit advice is different. she runs like 760+ bars on XC bikes. a) thats unorthodox, especially for her stature and b) affects other dimensions of the bike fit.

I am 5,11 and ride the M/L Supercal. Fitted a longer stem than usual 100mm -17 degree and a good amount of post is showing but the bike feels nimble and easy to maneuver at slower speeds.

Thanks for the feedback guys and gals! Much appreciated.
Now that the new Top Fuel has been released, it leaves for SC as the only XC option other than the Hardtail.

Well the original delivery date of February seems to have slipped to Juneā¦ probably just as well, feel tired, snotty, achey, headacheā¦
Cool stuff!
Does anyone know which type of Chain guide that is?
Has any of you put a chain guide on your supercaliber? Iāve been trying to get my hands on one by MRP since July last year but delivery kept being postponed. Yesterday I found the part at an online store from the UK and ordered it there. Had my chain dropped once since I own my bike and even I stopped pedalling immediately I got the paint chipped at the location right where the chainstay protection ends. That is also the location where the chain immediately digs into when being dropped so Iām also a bit disappointed Trek hasnāt provided some sort of protection there. I have a clear protective film on the frame but this got stripped by the chain right away. 
Same thing in the back - chain got dropped once, while I was cleaning the bike and turning the crank backwards and not paying attention. Stripped a layer of paint from the dropout immediately. Saw similar damage at another forum recently. All my other bikes are not that sensitive to chain being dropped as my supercaliber. But I guess itās part of the game. I hope I can fit a chain guide soon to protect the front. No ideas yet how I can protect the rear, other than paying more attention in the future.
Short update - the MRP chain guide came last week and I finally found time to put it on. Itās a pretty neat part. Can be a bit more relaxed now.

How does it connect. Is it under a press fit cup? What part numbers is it? I loose mine all the time and need to put one on.
It clamps around the bottom bracket bearing cup. The crank needs to be removed to fit it. The part is not made by TREK, it is a MRP Trek BB Clamp 30-36T.
