I just got a CycleX 4-into-1 Sidewinder 1500 miles ago and I think the quality, fit, finish, and especially the sound! are all awesome. Good tech support too. I am told by some of the experts here that Sidewinders will scrape on turn s and I don't doubt that they are right, but I think the latest version of these is pretty high and tight - I can't tell if some guys really lay theirs down on turns and I am a big chicken, but I can't ever see scraping these. Anyways even if you did not get Sidewinders , I rate them highly in all respects and they have a lot of versions.
