Having ridden solely longer travel trail and enduro bikes this year I wanted to get an XC bike for my more tame local trails and do a couple XC races. I had purchased a left over Intense Sniper Trail which with the biggest volume spacer and highest psi possible wasn’t even close to working for me. I had an opportunity to trade it back into the shop I got it from that a friend owns and with the bike shortage my only option was a Yeti Arc. More of a trail bike geometry and front travel wise but I’ve been about to install a 34 Step cast at 120mm to lower it down a little. I had the seat clamps come loose on the 2021 Fox Transfer first ride but I torqued them down and hadn’t had a problem for 60 miles so figured I was ok. Well I did my first race yesterday and a couple miles to go the seat comes loose and is just about falling off and at the finish line snapped clean off. So it appears my weight is too much for the hardtail as all my weight goes right into the seat which can’t handle it. A tall order but does anyone have an XC bike or even a 120-130mm light trail bike that’s worked for a 260ish weight range? In a tough position to ride aggressively at my weight so far and right now have a practically brand new bike with the seat clamps broken in half which are on backorder for who knows how long now so I can’t ride it.
