With the aim of going N-1, has anyone done this?

Looks like (CF the 29er I use as a cx bike) the BB will be 3cm higher and TT 3cm longer, neither ideal, angles aren't a million miles different though.

So using a mtb for cycling off-road, lanes and grit paths?
hmmmm, I'm not sure that'd work. 😉 8)

I have a 26" M2 that is adorned with drop (flared) bars as you describe - I use it as a 1-2 hour spin bike on the roads mostly - though have managed an all-day 75 odd mile spin as well. It's not bad at all, wouldn't like to be to bashed about TBH and the longer TT takes its toll after a while.

Jekkyl the point is drop bars and TT length.

It doesn't need to be perfect but I wouldn't ride it if it was shit.

built an old trek frame got off ebay into a dropbar hybrid/adventure/gravel/cx bike - suspect was of the age that had never seen a suspension fork and geometry similar to a touring frame - was marked as made in the USA! no discs - planet x cx fork on the front and frogleggee cantis with an adaptor on the back to work with 700c wheels - actually a very comfy ride - as well as local bridleways did a few multiday road rides typically 80-90miles/day - if it had disks would still be riding it

I have been toying with just this idea, got an old kona frames, essentially worthless to anyone else. I really like it but want to put a disc mount on use a cheap 29er wheeset, Cx tyres and drops run it 1xN as poor man's Cx bike/offroad tourer/bikepacking machine.

700x35 is not all that different diameter to 26x2.35 so handling should be fine.
the 3cm longer frame shouldn't be all that big a problem as to quicken up the steering i'd be wanting to run a shorter stem than usual anyway(I'm presuming the mtb has a slacker HA by a couple of deg.)

I have an orange P7 frame, with the F8 rigid fork.
it takes 700x35 no problem, head/seat tube angle doesnt change, bb height may be slightly higher.
i think the main potential issue if you are changing to drops is top tube length.

I'm not saying it changes.
I'm saying mtb frames usually have slacker H/A than CX frames.

Gary Extreme read the op it's a 29er frame not CX.

I'll show you it* if you ever come out riding with me again.

*the frame. Not THAT!

Yes. Cx first-timer racing a singlespeed steel 26" with CX Pro tyres (tubeless). And I beat a lot of people on nicer, bigger-wheeled, carbon bikes too. Forks are 700c disk, they didn't change the geometry or handling at all. Bars are Soma Sparrow and the stem is a 100 mm. This is a 19" Genesis, so the TT is quite long. Looking to place Top 10 in the regionals next season and debating the use of gears to do so.

Tyre choice is the biggest issue. There isn't a choice.

And a side on view in worse conditions, so you can see the TT length

OP is pretty incoherent and the title says 26er. 😕
ie. what does this *(CF the 29er I use as a cx bike)* mean?

If keeping the geometry as the manufacturer intended is of importance to you, you'd be better using a 26" frame with 700 wheels and CX tyres than using a 29er frame with CX tyres IMO

Post on the FB group. I ride most days or nights. What do you ride?

CF means "compared to".

I like how the 29er rides as a CX, no idea if cx frames have lower or higher BBs, I'll have a look.

I'm already running a 7cm stem on the 29er I think, 4cm on the 26er would be a bit daft, could move the saddle forward I suppose.

Just gotta try it I guess...

As proven in Tired's pics, it's already a bit daft. Go 50mm stem rather than moving the saddle.. plenty cheap ones around.

I put drops on a Dave Yates Diabolo once. I hated it, and have felt guilty ever since for doing that to such a classic MTB. Overall, it was too long in the TT and too low for my liking.

No, cf. means "compared to" CF is just 2 random upper case letters

Don't move the saddle, swap bars. Reach on my bike is the same as my road bike. But the bars meant I needed a 100 mm stem. Bars are a take on drops, so that's why the stem is extended. Mine are the narrowest 47 cm bars:

I would have the same reach and stack on a 700c cross bike, if I had one. EVERYONE marvels at the mud clearance, even if the looks are unconventional.

TiRed its not for racing and it MUST have drops.

I didn't know cf couldn't be capitalised. Pedantry-tastic!

Not to be stupid, but is it acutally N-1 if youve built a bike up?

Or are you planning to swap back and forth between normal set-up and cx, in which case why not just ride it as a normal bike with skinny tyres?
