My Sinister Splinter MX Large. 1.5in headtube (Superstar reducer headset included.) Adjustable headangle/BB height 63-67deg/13-14in 73mm BB 30.9 seatpost 12x135mm rear end ISCG05 X-Fusion O2 RC Shock giving 5.5 or 7in travel. Air spring pressure Rebound 4Stage Platform Compression adjustment This is one of the rarest frame you're likely to find. This has been hand welded by Frank The Welder, and the craftsmanship is excellent! You won't ever break her, and she inspires confidence in even the roughest of situations. The XFusion shock had brand new seals 2rides ago, and is an excellent match for the rear linkage. Unlike the previous Fox shock I had on it, the XFusion doesn't wallow around and is much more effective when climbing, and also when you really open it up on the rough downhills. I'll be sad to see her go, but I've too many bikes and too little shed space to keep them all.
