I dont have any problems with the chain coming off, it hasnt fell off even once. Which is just as well because this bike cant really fit a chain device. What is an n/w chainring and can you get them in 5 arm compact size?

Cheers

 Good to hear. I always used to have problems with my chain flying off when riding without a chain device or narrow-wide (n/w) chain ring.

These are narrow-wide chain rings: www.pinkbike.com/news/Race-Face-Narrow-Wide-Chainring-Tested-2013.html
In the end it doesn't matter which one you get, all of them work really well, and prevent your chain from dropping.

Absolute Black makes some aswell in 5 arm size (both 110 and 130 BCD): absoluteblack.cc/cx-rings.html

 For what it's worth, you could easily mount a seat-tube chain guide from MRP or E.13 if you wanted to.

 I didnt know 130mm bcd existed, i must be old school compact is 94bcd though so i wouldnt be able to get one that fits, one of those seat tube mounted guides is a good option, i just need to find one in 31.8mm

 @Seraph: Depends, for normal 104BCD there are plenty of options, starting at €35 on CRC or €45 at your LBS. Don't think there are much options for chain guides for that price. Also this is lighter, less hassle / less things that can break or go wrong, and it works perfectly. Used mine for over a year and never dropped a chain, while my chain was already dropping every 20 minutes during XC rides with a normal single speed chain ring. Even rode bikeparks, dirt jumps and downhill with it, and not a single drop.
But if his chain doesn't drop anyways, there's no need to change anything

@Sean-s-1991: Pretty sure I have 130 BCD on my Shimano Hollowtech II road cranks. I thought 110 was compact, so my bad about that.

 Thanks
