My workbench stands bare. My projects are finished. I have a hybrid, shopping basket, and mb Thats enough I told myself. Then.... a thought hit me. I don't have a full on roadie. Thus I mran to keep my eyes open for a frame. But I'm not sure if the 20.5 inches tha makes a perfect fit for my mtb will work for riadie. Anyone care to share some wisdom that I may build another bike that I can't stop riding?

Yes, frame sizes are different. Bikes are usually marked by seat tube length. All else equal, the MTB will have a much shorter seat tube than a roadie, and much more clearance between the top tube and the berries. If you're riding a 20.5" MTB, you sound like a very big guy and you'll probably need a roadie in 58..60 cm range.

Round 192cm and 86kg. It took a looooong time to finf a frame that big in Korea. Lucked out at an lbs when a sude imported a fuji the wrong size. Perfect for me though. I can adapt a smaller frame as a hybrid easy enough but I can't tolrtate the top tube being too short with drops. I just can't get far enough back ro be comfortable. Thanks for the nfo. I'll have to keep an eye out for a large roadie frame. Itchy fingers and no project...

Yeah ... 192 cm, that's 6'4" imperial. Look for 60. Maybe even 62.

Didn't you already try a roadie that you ended up hating, or am I thinking of someone else?

Found these larger frames (because I had nothing to do):
Pro-Lite Cuneo 60.5cm $233

Ridley Triton 60cm $320 (fork is included in the picture, not sure if it's really included)

I'm thinking that you should use one of the on-line fit calculators to establish your basic frame size. You then can tinker with stem reach and seatpost, crank length, etc. My gut impression is that you're looking too small right now. PG

Not sure if the 60 will fit you the best, but I love my Cuneo!

I did hate that road bike. Size issues and poor quality. It made a good hybrid though. Going to give it one more chancebut tbis time but from the frame with decent quality parts. Still won't be carbon but probably a nice aluminijm frame.

Did you find it challenging to find a fork to go with that?

Anyway, to the original poster, if you want a flatbar road bike, I saw bike24.com has some flatbar parts. If I had lots of money, I'd probably do it. (The Sora crankset on that site is even available with a chainguard.)

Oops, just realized you might need a crankset longer than 175mm.

Made me a flatbar road bike already. It rides nicely but its slower than my mtb with slicks due to the gearing. Not sure jow much I will actually ride tbe thing, but it might be nice to have a decent roar bike to round off the stable.

Gotcha. Hope this experience is better.
