OP, check out reviews of the detonators online, there are a lot since a lot of independent small bike shops carry those tires. Mine does. I hear they flat a lot and hence their name "Detonate". Personally, if you want a good cheap tire I would try to buy Michelin Lithium, I recently bought a pair for 40 bucks total. I got them at JensonUSA.com. Tires are light, durable and spin real nice and most notable difference is the cornering. A big upgrade from my 2 previous road bike tires (Kenda Kontender x 26, Vittoria Zaffiro x 23)
