Hi Everyone -

Trying to figure out my bike situation. Right now I ride a specialized hardrock MTB. (Alum frame but still heavy) I'm only getting about 13-14 mph on the top gears, so I'm trying to decide if I should just get smooth tires put on the MTB (anyone have a cost guess on that one if a LBS does it for me?) or if I should get an okay-ish road bike. I'm currently looking at the MOTOBECANE vent noir at just under $700.

Am I better off investing in the road bike or should I wait until I have a better feel for Tris and just get some tires for now?

I'm currently signed up for a July Sprint and Aug Oly.
