"mud gets in-between the chain links and lifts it off of the chainrings as
it comes around and chain drops"

I had that exact problem at Alpenrose. My thoughts are that the "wave"
type narrow/wide ring might be less susceptible to that than the
traditional narrow/wide ring. Otherwise, love the 1x10 (I run 40/11-28)

One problem I had with a 1x10 setup in cyclocross is that when the mud is
VERY thick (Washington County fairgrounds a few years ago) the mud gets
in-between the chain links and lifts it off of the chainrings as it comes
around and chain drops. This was with clutch derailleur and narrow-wide
chainring.

A chainguide solved that problem:

That was my costume for Bend last year!! It was fun and racing with a full face actually helps motivate you!! I took way more sketch passes than I normally would have and most of them work out well!!

You do however need to wear a MTB helmet with a visor to rock this look correctly. And we are gonna say something about it. Just buy one that matches your socks.

Crank arms are SRAM Force Carbon, Chainring is Wolf Tooth Components Drop-Stop 38t. Rear derailleur is SRAM Force with Roller Bearing Clutch. The Shifter is Shimano Deore XT.

Thanks Dennis. That's abig help. I'm glad to hear about the handling advantage of flat bars. I mostlyMTB these days too and that just seems like a way more natural position fordifficult terrain.

What derailleur andshifter setup did you end up going with? I'm thinking of an Sram X7 shifterwith a Rival derailleur but maybe it would be better to go with the full X7setup. I have X0 1x11 on my MTB and I love it.

Thanks!

Chester,1. 1X10 Drivetrain: I made this change last year. I'm on a Trek Boone cyclocross bike. I initially set up the system with a 40 front, and 11-28 rear. After David Douglas in 2015, I changed to a 38t chainring. This year, after David Douglas, I changed to an 11-30 cassette. That gearing (38t front chainring & 11-30t cassette ) has worked well for the 2016 season. But don't automatically adopt my gearing. At 62 years of age, I don't have the power of my younger days.

Chester,

1. 1X10 Drivetrain: I made this change last year. I'm on a Trek Boone cyclocross bike. I initially set up the system with a 40 front, and 11-28 rear. After David Douglas in 2015, I changed to a 38t chainring. This year, after David Douglas, I changed to an 11-30 cassette. That gearing (38t front chainring & 11-30t cassette ) has worked well for the 2016 season. But don't automatically adopt my gearing. At 62 years of age, I don't have the power of my younger days. I like the simplicity of not having a front derailleur, and the lower likelihood of dropping chains. The narrow/wide tooth chainring profile, and SRAM clutch rear derailleur do a good job of keeping the chain engaged over rough terrain

2. Flat Bars: Aside from the occasional (friendly) heckling, I am really enjoying flat bars on my cyclocross race bike. I have 4 decades of road experience, but started riding MTB 3 years ago. The goal was to become a better cx bike handler. I fell in love with MTB, and my road bikes are now collecting dust - but that's another story. My bike handling in cross races has been much better this year. I"m not absolutely sure if that's because I changed to flat bars in 2016. However, with flat bars in cx races, I'm successfully using the MTB "ready" position lots. Additionally, I'm utilizing one-finger braking - which allows me to approach features faster. Analysis aside, flat bars are just plain fun. I suggest you experiment with appropriate width of bars. Cut bars narrow enough to avoid conflicts in race traffic and minimize wind resistance, but wide enough to assist with bike handling. I started the 2016 race season with 680mm bars. They were much too wide. I'm currently running 635mm wide bars and like them.

Hi. I'm thinking about converting my 2x9 drop-bar 'cross bike to 1x10 with flat bars. If you're running a similar setup please tell me about it. I'm especially interested in how you set up the drivetrain and anything you like or don't like about riding cross with flat bars. I have some ideas but I'm interested to hear what's worked (or not) for other folks. Thanks!
