I saw these same wheels on ebay today for $1000. I am considering the purchase, but still thinking about it. I am curious about why there is a front brake disc, but no rear brake disc; also no sprocket bolts?
I am new to blogging and don't know the lingo yet. What does "ttt" mean?

When most people convert their bike to a supermoto they buy an oversize front rotor and use the stock rear rotor. Again with the sprocket bolts they most likely got bolted back onto the stock rear wheel.
