looking at buying the Redline Monocog but my LBS only has a 29er in stock. the 19" frame fits me pretty well, my question is since the 29er with 19" frame fits well should i look to purchace the 21" frame of the monocog since it has 26" tires. i know i should look for a shop with the bike i want but with the price of gas i dont want to be making any long trips that arent needed. thanks

I would focus on the top tube length and, if it's the same then the 21" should work. How tall are you and, what is your inseam measurement?

i am 6'3" and my inseam is 34"
