|I have been thinking.... not always a good.
My girlfriend is 5'1" and I would like to have a cross/ road bike built for her.
-700c wheels are out of the question, not enough stand over clearance and astheticaly displeasing.
-A few months ago in the image archive, I located a bike built to accomidate 650 and 26" wheels, my question is. What are the actual diameter measurement of a 650c wheel, (I can figure out the 26"....thinking again)
-ideally, being able to switch between two wheelsets would have its advantages.
-if the 650 diameter is greater than the 26" (including tire), would it be possible to include both canti posts, canti cable guide and rear stay pivot drilling? Granted long reach calipers may be used. Can the same be said for the fork?
-top would be on the short side 49cm. Seat tube angle 73. and I am trying to decide on the chainstay length, I am thinking short to keep the frame fast, 40cm.

|- A 650c is 571mm and a 26" is 559mm (Note - this info from the 650C tire search post on this board). Swapping between the two rim sizes is going to cause you some issues with the brake pad alignment (Unless you want to go disk!)
- Cleatgrrl (who posts here as Jimena) had a very small custom Gunnar made for her. She has a pict of it in this post Sadlebred "smaller (under 48 cm) cross bike" 12/6/02 9:12am

|I am 5'1" and was looking to buy a cross frame a while ago. I found there weren't really many options - Surly and Jamis had complete bikes that were small enough but I wanted better components, and Somafab (small shop out of San Fran) and Surly seemed to be the only framesets in my price range. After that I thought about sucking it up and getting a custom frame, but through a few huge strokes of luck I ended up getting a new 44cm Indy Fab for a really good price (still way more than I was expecting to pay, but...). It does have 700cc wheels, and I find the standover clearance is fine and since I have tiny feet toe overlap isn't really an issue either.|

|I would really like to see the 700c wheels on a frame that small.
Both myself and girl think that the asthetics are displeasing, I not trying to knock your bike. My friend does have a 46cm Viscious disc 29'er and does not look bad.

|I've got 700c wheels on a sub-48cm frame. it doesn't look beautiful, but it works.
as you probably know from the thread somewhere below, there are no 650c cross tires. there is a selection of 26" cross tires. still, all the good stuff is in 700c, and I would get 700c wheels if I could. consider custom. Tom Teasdale built my frame: www.tetcycles.com. $580 for frame/fork in True Temper OSCRX tubing, and I think he did offer a cheaper option (some Columbus tubeset) before.
for reference, I'm 5'3" with a 29" standover in MTB shoes. in retrospect, I'd have gone with no standover clearance (currently have about 1") for a large main triangle.

|My bike is at the shop right now, actually, getting some parts put on it and whatnot. I'll take a picture once I get it back and I'm back from the holidays.
You're right - it's not the most aesthetically pleasing setup, but as weiwentg pointed out getting cross tires for 650cc wheels is a pretty difficult endeavor. I do have enough standover clearance with the 700cc wheels, too.

|I would also suggest checking out the Soma and the IRD (Interloc) in a 42. Should be ok on standover height. They are similar in geometry, made out of different types of steel though. Good luck!|| |
