While cruising the CX forum...

... the question of how much abuse would a CX bike take riding on single track came up and it got me to thinking has anyone built some thing like this?

Walt: I will hold back on the "word salad"... LOL

It would be fun to have a "hybrid" form of a CX for trails, wider tires and room in the frame for them, really good brakes, Smaller C-rings up front, bash guard to huck a logover once in a while if ya don't feel like a runover, but still the CX platfom, not a monstercrosser.

Hum, I think the AcyOx torch is talking to me?
Al hail John Tomac the king of drop bars!

What you describe is exactly what I always thought a monstercross was.

Funny you shoud bring this up...

... because I just finished a frame sort of like this.


hybrid by jimn, on Flickr

72 degree HT
74 degree ST (I like to sit kinda forward)
575 mm TT (I'm about 6'1)
bb drop 45
425 CS
trail ~50
Clearance for 2.25" tires at least.

I'll let you know how it rides. Should get it built up for a test ride this weekend.

That type of bike is becoming more and more popular. I don't know what you call it, Monster-cross, gravel crusher, 29er with curly bars, expedition bike…

I built this for a friend who likes to ride from his house through gravel and bike paths to the trailhead for a little bit and then back home. I tried to set it up with the ability to run 2.1 29er tires, and CX cranks, but there just want enough room in there and we ended up with a mountain crank.

Its suspension corrected, if he wants to go that route. I set the reach between his setup for flat bar and curly.

It rides well, and is super fun knowing you can just leave the house and decide where you're going when you get there. And for a super muddy cross race it would be the bomb!

FWIW, with clearance for 26x2.25 tires, using HOX5CS chainstays, 425mm long, I can fit road cranks no problem. I think I was using a 118mm bb spindle. Cranks were Suntour Cyclone 175mm.

I haven't checked, but I could probably squeeze a 52 tooth chainring on the outer position of the crank.

I guess I'm threading a slim line here and it might be in my mind only that I can see what I speak of ...

... light weight, road geometry, great brakes CX bike that will accept wide tires but "not" a converted MTB with drop bars ...

Am I splitting hairs with an hammer?... LOL

Mine is road geometry, as I designed it for a lot of commuting use. It builds up at just under 20lbs with knobby tires.

I just dont really get the whole monstercross thingy. It seems to me that you are taking some attributes of 2 bikes to make one bike that isnt really better than either. I ride my cx bike on singletrack with 42mm tires and it is really fun. If something is too rough then you can hop off and run over it. If I feel like the cx bike isnt enough for the singletrack then a mtb is in order. To me the beauty of a cx bike is the ability to ride road and singltrack in a single outing efficiently.

i sorta thought that 'monstercross' named cross bikes with bigger than 35mm tires. the thing with monstercross is that it put a name on something people were kinda doing already. that's fine but it leads to some confusing interweb forum posts!

The 42mm tires on your 'cross bike push it toward the "monster"(I really dislike the term) cross side.

My Adventure Bikes are more capable off road than a 'cross bike and better on the road (paved or dirt) than a mtb.

Sturdier and can take bigger tires than 'cross frames with geometry close to a "race" 'cross bike (NOT road geo).
With smaller or road tires can be used as a non-race road bike. Designed for dropbars. Comfortable ride.
Think a performance bicycle version of a STI or Evo car.

I'll be getting 2012 Cannondale Quick CX1 next week - hopefully the weather will let me test ride it next weekend. My goal is to have all around (ok, not go to grocery store) bike that fast enough for occasional extreme commute duty.
