Okay ... I've raced a 1x10 for 4 CX seasons so far. Through all of this, I
have learned a LOT of valuable lessons for a 1x setup. First - I heartily
recommend them - though the chain drop issues can be a challenge to sort
out at first.
This year I will be racing CX with a 2x10 setup for the first time. So
catch me after a month or two of CX season, and maybe I'll change my tune.
Maybe not. we'll see.
My thoughts... in no particular order:
* the Paul chainkeeper did NOT work for me - the chain would literally
'catch' on the aluminum of the chainkeeper, and bind up, and then RIP out
of the keeper - on the course, it's impossible to put it back
* I run an MTB SRAM setup, which allows me to mix-n-match the Road/MTB
components (i.e. traditional brifters with SRAM MTB derailleurs)
* for the first 3.5 years, I ran a traditional long cage MTB derailleur
* the last half of last year, I switched to a SRAM Type2 (clutch) based
medium cage
* it made a HUGE difference in keeping the chain tensioned, quiet, and
less chance of dropping
* forget about any stupid finger-like keepers (i.e. the "k-edge" style,
etc...) they're worthless
* I found chain guards on both sides ineffective (without a clutch based
derailleur), as CX courses can be so rough, the chain would bounce *over*
them)
* forget about any DH style roller / chain keeper assemblies - they work
great - but they're so bloody noise and you lose a huge amount of
efficiency from chain drag on the rollers and bash guard keeper edges
I did end up finding an exceptional chain keeper ... which ironically -
mimics a front derailleur. The E-Thirteen XCX worked perfectly for me both
forward and back pedaling, very little issues. Twice I did manage to
derail the chain on the front, both times the keeper fed the chain back on
to the ring. I did NOT derail the chain after switching to the medium
length rear derailleur with the SRAM Type2 clutch. The XCX comes in both a
downtube mounted and BB mounted version.
It's *critical* that you have a good chain line on your single ring up
front. If you don't, you'll have tons and tons of issues like I did. I
typically ran a 44 or 46 ring up front with an 11-36 cassette. Because my
bike frame was designed to accept 2.1" MTB size tires in addition to CX
tires, that large of a ring caused issues with pushing the chain line
outboard. Most CX bikes should have a lot less of an issue, and if you
run a 36 to 40 up front, that will reduce the potential issue...
Once I did have things settled in, I really like the 1x10 setup a lot.
Simple, easy to maintain, worked great once I got over the derailing
issues.
