I changed my frame and I might change my tires too. It's still an XC bike which is what I use for races, but I think I need new tires. I also got new 28mm internal width rims that are tubeless ready. I am gonna be running tubeless now in a week or two. Which is also why I'm getting ready for an XC race. It's just a tune-up race but I'm still trying to get better on the trail like I used too. I run an Ardent 2.25 EXO/TR (Front) and a Ardent Race 2.2 (Rear). I'm changing my front tire for a Forekaster 2.35, and I'm still tryna pick a fast, semi-slick tire (which is great for mud). No, my tires right now aren't worn out yet or not for me, I need loose/wet tires for the race. I tried my setup on a soft, slightly wet trail and my AR 2.2 slips sometimes. But I've heard that Aspen or RR's are great for mud? I don't know yet. Speed is optional, but what I need is Grip. Which has better grip and which is more versatile? Let me know. BTW any size will do. From 2.25 to 2.4WT (Both Aspen and RR).
