I've really only found mixtes that are around 50cm. I would love to find one that is 52cm, or at least had a longer reach. Since I can only find these smaller ones, (and when you go to the earlier Raleigh catalogs, you will see that they didn't come in lots of sizes) I just adapted with different bars and a different stem. I can't imagine that anyone is going to do any serious mileage on these things. Mine (50cm, I'm 5'5") is just fine with the bullhorn bars I put on it. The moustache bars that were on it previously just cramped me, but still, for riding around town it was fine.
