Haha probably because with the 24" rear wheel you have a lower center of gravity which makes it handle better. I kept with the 26" wheels because I already got new tires for them so I may as well use them!
oh yeah and dont get me wrong, I like the 26" wheels also, I have three of my bikes that urrently have 26" front and rear.
The cruiser frames are great for me with 26" wheels or 24"
tThe taller "Diamond" shaped frames like my old MTN bike and the 700c fixie bike are taller crames and with 24" wheel on the rear or front and rear they sit more comfortable for someone like myself that isn't long legged.
I know from what I been seeing here that your gonna have a real nice ride when you get done YILDS.....
Im enjoying watching g you round up all your parts and pieces, I have about as much fun doing that as I do riding the finished product, and then after a while I like to change some things up a little just for the fun of tinkering and possibly making an improvement somewhere on the bike.
The entire process is fun to me and I dont have to spend a fortune doing it.
