Another review Here that’s worth a read. I ride a steel CX bike, and love it its made stuff that’s pedestrian on a MTB seem like a laugh and they are rapid in the right (not necessarily my!!) hands. So its worth a go to liven things up. From reading here it seems to be a half way house this bike I think if its really muddy you could struggle with full mud guards but I like running 35 c tyres and don’t run mud guards due to gloop so you might be grand.
Not sure on the wheel spec on this bike being tubeless but it’s worth a shout, I’m still using tubes so can’t comment but its an added cost if these wheels are not. 105 is good stuff for a cX /commuter it will go all day and it cheap (ish) to replace so no worries there at all. For a winter road/ commuter the cX is a good choice for me anyway plus off road it’s a laugh.
Hope that’s if some help!
