They are a race day tire only. They are not very durable nor do they last long, but are good for racing, and have a lot of grip. I would say if you want a tire that is much more durable with plenty of grip, and very racey, look at the Maxxis Ikon. The EXC version is around 520g, or the EXO (thicker sidewall) is around 575g. I have put about 550mi. on mine in the last month, they have shown very little wear, and grip on everything! They roll fast and smooth, and don't slow you down.
Renegades are great for a race day tire, for front/rear or on the rear.
Another very good combo is the Ikon front/rear combo
or Racing Ralph front/ Ikon rear combo.
RRs have a little bit more edge knobbies which make them just a hair better for a front tire, but the Ikons work just fine.
