CF Bike as adventure bike?

So I purchased a NEW UNUSED CX Rayleigh rxc Pro 2014 carbon fiber frameset for cheap($400). It's a 900 gram frameset with a 400-gram enve fork.

Should I worry about riding it as an adventure bike is it designed to handle the shock and all that?

Write it like you stole it. Cheap used CF, better dirt than pavement!

Sorry should have been clearer.

Bought Frameset new just to see what CF is like. Then decided why not turn it into an Adventure bike. But I see most adventure bikes are steel.

So is a performance CF CX frameset upto it?

The frameset is so damn light.

here is the link

https://community.raleighusa.com/bik...canti-frameset

As you can see its a race ready CX bike in CF.

I'm just a bit concerned that:

a) CF in general is not designed for the rigors of off-roading
b) This particular design is for CX racing which is through soft mud not rutting over hard tree roots, rocks etc.

The fork in particular worries me.

I do enjoy riding it as an endurance bike so don't want to wreck it.

You seem very concerned. Dont use it if you are hesitant.
I will say that your description of CX is...perhaps not as accurate as you think. CX races can include significant tree roots, quick hard drops downhill, bunnyhopping, crashes, curb hops, and more.

But really- dont use it if you are concerned. Buy a drop bar monstercross frame, slap 50mm tires on it, and dont be concerned itll break.

But are my concerns reasonable?

Thanks, but I just don't know enough about CX CF performance frames to know if they are reasonable.

I don't want to ruin a good frame it wasn't design for riding off-road. But if it was designed to handle the type of riding your describe, great, I'll use it.

Sorry. Its a frameset bought new from RandomBikeParts

I bought it new and built it up to use an endurance bike. But wanted to ride some gravel etc on it.

Carbon is able to handle off road use. There are hundreds of thousands of mt. bikers using carbon, you don’t typically read much about frames not up to the task.

That said they can be damaged, but so can any frame. I had a buddy on a new (last year) carbon Specialized mt. bike, had a stick get poked thru the downtube. He got the frame repaired at Calfee, good as new. It was actually easier to repair this in carbon then any frame damage that would have occurred on aluminum.

Salsa Cutthroat Carbon - one of the more popular bikes in the wild. Works great. I do not have it but I ride regularly with a friend who has one. It is a great bike.

There are also a lot of CF adventure/gravel bikes UP, Cutthroat, 3t to name a few. The disadvantage you have with that frame is limited tire size and limited attachment points/bottle bosses. Enve is one of the better brands for CF components. If the frames limitations don't bother you will have no problems with it as a gravel/adventure bike.

Ill play devil's advocate and mention that just because carbon is used for MTBs doesnt mean this specific frame is up to the task of hard use. Im not saying the frame isnt able to sustain hard use, just that frames are made differently for intended use. A lot of responses are along the lines of 'carbon is a material for hard use bikes so you are OK'.

Right. That was my 2nd Question

I'm pretty sure those mountain bike frames don't wear 900 grams. I do know that this is a performance CX frameset are they normally designed to handle off road stuff.

There is a massive difference between a carbon mtb frame and a cx/road one. Mtb frames are not that light. Take the Ibis ripmo for example which comes in carbon and aluminum. The carbon frame is not that much lighter than the metal version. Also mtb frames have different EN ratings on them for cross country vs enduro/downhill, etc.

Your Raleigh most likely is not rated for carrying a load since it's a pure cx race frame. So you going to have to be more specific when you say you want to use it for adventure use. So you just want to put big tires on it and tackle some dirt or actually go adventuring in it with some bike packing?

That's what it was designed for then. CX racing is dirt racing without the big gaps or jumps.

Good point. I was mostly stating that carbon is tough and the material is not something to be concerned about.

That said, it's also only $400. If something broke, it's not like needing to replace a $2500 Colnago frame. A Chinese replacement would likely work..

The Ibis Ripmo is a enduro full suspension bike so not exactly a good example of a lightweight mountain bike frame. Look at some XC carbon hardtails instead like say a
https://www.unno.com/aora/
which is only 790 grams. There are plenty of super light XC carbon hardtails out there. I ride a unbranded (its a fuji) carbon CX bike as my road, gravel, and light trail bike and it hasn't killed me yet. I've done some really stupid crap on it too.

A cx bike should be good enough for general trail riding as long as you're not hucking off of things or shooting down technical rock gardens. A race bike is also probably not designed to carry a lot of load (eg, bikepacking gear) but should be fine for day rides with minimal gear.
