The suggestion was to use the MTB for CX, & save you road bike for the road.
I've seen quite a few MTB @ races, some even use MTBs with suspension.

You don't need a road frame to get to 19 pounds. That's within reach for most aluminum CX frames.

I understand that you insist some side-pulls have enough clearance for CX racing, and that may be true for some course conditions. But is there a reason cantilever brakes aren't acceptable? I mean, why would you rule out a frame just because it uses cantilever brakes?

He claim its solely on looks...
He doesn't like the way "wings" look...

I don't have any around to bolt on. Also, my spec for a "road bike with clearance" doesn't require canti's. I understand that most dedicated CX frames would love canti's.

My spec is for an allrounder frame suitable for average joe road racing, cx'ing, credit-card touring and other fun stuff.

(About those who say I don't like canti looks -- I understand that my remarks can get buried in heaps of text but I *do* like the looks. I just have noted that they stick out into the wind and I'd rather not have them on a road-racer, paceline duty bike. I just don't happen to need 'em. If I have to find some to get my wish of a road frame with clearance then I'll do that, but I don't see a huge reason to tie the two together.)

OK, how about this, I just thought of the Trek 2.1 -- available $200 secondhand. Eyelets (is this right?). Racy geometry. Lightweight. I can't find any clearance specs but apparently they're famous for retrofitting to 650Bx38mm which is cool but I don't need to do. Anyone know a link to clearance specs for this frame?

Ghost Ryder

It does exist...
Its called a cyclocross frame.

OK, there's working on roadspeed from the 'cross direction. Then there's working on versatility from the road direction. Nothing odd in such a design concept.

No reason to be forced into a 'cross frame if you just want clearance and a roadframe. ...Yet, with such a bike much in CX and gravel-grinding is available to you. Even while you can still hang with your roadie paceline pals.

Anyway, we possibly have the Trek 2.1. I've now heard about the Jamis Endura and Fisher Cronus as sub-18-lb maybe's. (I see used Endura's going for $500.) Gunnar Sport is an option. Such bikes might fill the bill as fast on the road but also something you could slap a CX wheelset on or any other cushy, tolerant set of 32's for gravel grinding say. ...And still take a pass on the canti's if they're not what you're into.

buy a quality old 27" wheel race bike and get long reach brakes and 700c wheels.

see you later.

Swing and a miss. The spec is that it has to be 19 lbs or so. Certainly heavy old sport-tourers, etc., already have all the right specs except for weight. So when will the Sport Tourer type come around in generic carbon? Or, more specifically, a race geometry bike with clearance. Well, I may have found a couple, as mentioned.

i didn't miss. the reality is, the bike industry builds for very specific duties. geometries, frame materials, and drivetrain/mechanicals are all very specific to specific needs. SPECIFIC is the key word. you are asking for a sub 19lb race bike that can also go in the dirt AND do racks and bags for tour/commute.

and you want it for cheap.

you missed. and if the bike industry ever tried to build such a bike they will have missed too.

take care.

JeffOYB

I said cheap on the secondhand market -- so any big maker would qualify.

Trek Pilot is almost filling the spec. Any carbon frame with eyelets will come close. If it also has clearance it'll likely be fine. Likely any big-tube alum or carbon frame with clearance and eyelets and no canti's will be under 19 lbs with tubies and will be cheap secondhand if from a big generic maker.

ok.
