I just got back into flatland so no crazy spinning tricks yet.. I ended up going back to my Ares 1.9 because I couldn't seat the Trackmark well enough for it not to wobble a bunch.Here is a photo with the trackmark on the front and ares on the rear. You can see the size differences.
Hi razorlab, nice looking bike! What stem is that? Thanks.
I have been running Primo E-Comets with kevlar beads on the front and rear for a couple months now. I really like them. They are grippy and roll smoothly. The tread depth is fairly low when new and they are pretty soft, so longevity probably won't be great. But for what they cost, I don't mind them not lasting as long. I have 1.95s and they measure narrower than the Ares 1.90s that I was using before. Overall, I am real pleased with them.
