Last question(s) before buy day: mtb frames for cx....Farmpunker

Howdy all,
I know this question has been asked a number of different times, in a number of different ways. But I wasn't able to find a satisfactory answer in the forum archive. This will be my last series of questions before buying a Jake the Snake. So:
Mountain frames for cx application. Why not? I'm not going to be racing at an elite level so 26 wheels shouldn't bar me from entering. And wouldn't 26 wheels accelerate faster anyway? Hop off, hop on, take off faster. And a mountain frame would seem to be easier to size. I'll get a size larger than my mountain bike, to make room for my arm and shoulder, and to give a more stretched out position. The sloping top tube would also eliminate the annoying standover problem. Then I'll throw a set of drop bars on and some barcons or used STIs and have a go.
There are also more good used mountain frames kicking around than there are cx. Jamis Dragon, Rocky Mountain, plenty of light alu frames.

Hey Farmpunker--

Do you have most of the parts to do this already? If so, then I say go for it and post pics once it's built. Also, I have a 17" Jamis 525 frame that I'll sell you for really cheap if that's the size that would fit you.

That said, if you're starting from scratch I would build up a real, 700c-wheeled, true blue cross bike. Shouldering any frame with a sloping top tube will be tough unless it's a 21"-22".

Tire choice is another thing that may be a problem. There are not too many skinny knobbies for 26" that would rival a true CX tire. I think 26" wheels will accelerate slower because of the increased tire width. Besides, acceleration has tons to do with fitness and gearing.

The only upside I can see to going with a 26" wheeled bike is that if you already ride an mtb, the parts will be compatible with your stable of mtbs. Otherwise, cx bikes are great on the road, challenging on trails, and perfect for cx races.

26's will "roll up" faster, they'll also "top out" faster (usually not a problem in cx) but tire choice is limited and 700's do roll over alot of stuff easier which helps make up for their narrowness. IMHO build up a true cxer, frankenbike it if ya have to, shop used, there are all kinds of deals to be had. In the long run you'll be happier on an actual cx bike
Thought as much...Farmpunker

Thanks for the responses. I asked more in the interest of satisfying my curiousity than any true desire to build a mountaincross freak. I mean, if it was that simple and effective, then there would be a lot more of them around, and more talk on the forum.
Then there was the bikelust factor. I had thought about putting an ebay bid on a Rocky Mountain Vertex SC bike... racing it in the summer months and then converting it to a crosser in the fall\winter. But I really do want a more dedicated pavement ride, and will content myself with buying some xc parts for my fullsusser come spring (Mavic tubeless...).
And just a minute ago I called my closest Kona dealer and found that the Canadian price for a Jake is now only 1400, down slightly from spring\summer. And I found my first race of the season, too: October 6th. Better get moving. Yeah.
