A unicorn, I like that. I think they might be just 12, but so far they seem to be doing fine for me. I had Alex wheels with a deore hub on the back of my G.F., 32 hole, lighter guage spokes, but these wheels seem to be stronger IMO. Where I ride the roads aren't nice at all and with no suspension on this build, cornering and general top speed feel alot more stable. I think other posters were right when they've said that Huffy must have been payin' attention to consumer demand. I highly recomend this bike. Mine gets 140 miles on it some days. Only had this build for alittle bit but I feel alot of miles are gonna pass under those tires.
