Di2 or CX1?

Especially for light weight issues concerning cyclocross / touring bikes & parts.

Any suggestions on a narrow wide chainset to go with a Di2 build (not Sram).

If you already have a crank, Wolftooth makes some nice stuff. There's also AbsoluteBlack. If you are looking for a crank, the Easton crank looks awesome, but I have no hands-on experience with it (and it may not be compatible with your frame - which is my problem).

It should work with any frame except Trek, unless someone else is doing BB90. CINCH cranks are effectively BB386 cranks which work on threaded and BB86 bikes in addition to native 30mm spindle BBs.

Deem, why I read this thread :)
I was convinced, I´m going to build my CX frame with Sram 1x. Now I´m thinking Shimano Di2.
Sram would be 400€ cheaper.

I have the Easton crank, I can't speak highly enough about it and the Easton chainring but the BB is trash. It crapped out on me in less than 2000km.

I have a few thousand miles on both platforms. I switched from CX1 to Di2 (XTR derailleur with R/785 levers and RS785 calipers).

I have to say, I miss my CX1 groupset. For one, and most importantly, CX1 is lighter (this is the Weight Weenie forum, right? Also, see my earlier comparison here: http://weightweenies.starbike.com/forum/viewtopic.php?f=4&t=146312).

I also really like the modulation of the SRAM Force HyrdoR disc brakes, moreso than Shimano. The pad engagement on the Force calipers is perfect. The Shimano levers pull almost entirely to the bar, even with max reach adjustment, which I really dislike. And lastly, I love the very tactile response of the SRAM Force shift paddles. With the Di2 levers, it's hard to tell if you've shifted.

Wolf tooth has even a 36T Easton cinch. Easton offers 38T as smallest.

I have the 36T on order.

A bit off topic, but anyway...
You can also (if you ever go 2*11) buy a 110 BCD spider from Kent Eriksen Cycles.
Then you get 46-47mm chainline. I have this spider with Wickwerks CX chainrings (44/34).

I also use Sram PG-1170, 11-36 cassette with my 6870 RD.
I would buy the XT Di2 RD if i could use it with 6870 FD.

XT RD will give better chain retention?

Make sure you bleed the brakes when all adjustments are “open” otherwise free stroke adjustment is not functional IME.

Yeah, that's my first step when doing a bleed/install. I just prefer the feel of the HydroRs.

Running CX1 on my A and B race rigs for cross over the past 4 seasons with several thousand miles on each. Absolutely love everything about it, especially the reliability on race day. Averaging about 15-20 races a season including some big ones like Gloucester, NoHo, NBX and CXNats. Nothing sucks more than driving six hours to a race and then DNF'ing because of a mechanical. With CX1, knock on wood, that has yet to be a problem.

My 14 year old son who is impossibly hard on equipment ran CX1 Force all CX season despite my recommendation for Di2. He loved it and is s SRAMY for life now but for me it was not reliable and finicky.

The clutch RD, lack of chain drops and brakes were phenomenal. The brake lever- not so much. Sticky piston problems abound.

He had the left hydro lever replaced by SRAM once for free and serviced once more (paid for by SRAM as well again) a few weeks later for same sticky piston problem in a different new lever. My son still swears by SRAM and their taking care of customers but IME you dont need it with Shimano.

I think ideal would be: clutch XTR Di2 rear, easton crank, Kogel BB with CX seals, SRAM cassette, SRAM calipers and Di2 shifters with sprint and climber shifters all over the bars.
