I'm a 220 lb, 62 year old newbie track racer. Loving it. Found a PlanetX carbon stealth bike on ebay. Now I need new wheels to go with it. Have been racing on Ksyrium elites which work just fine. But, of course, expensive wheels will increase my speed exponentially. No, really I just want to treat myself. Have been thinking of carbon tubulars, 60 or 88. Is there any reason to choose one over the other. I ride on an outdoor asphalt track (NE Velo in NH).
