Doing a new build, and particularly stuck on what fork to get. Primarily for XC racing, I go fast but I don't abuse my bike. 5'8", 150lbs. Kona Kula Primo frame, i beleive it's designed with 100mm travel more in mind.
The Fox f100rlt looks nice but at 3.5lbs and $650 it's heavy in two ways.
The Manitou Skareb is kind of in between, comes in at 3lbs and $450.
The RockShox Sid Race is the lightest at 2.87 and $400. Should note that this one is 80mm while the others are 100. Would be nice to go with this one but nobody really seems to be overly happy with it compared to the others.
Anybody used any of these forks? Any recommendations or advice? Weight is important, shooting for under 22lbs, but I don't want to shave half a pound for something significantly worse.
I've raced on lots of SIDs: most recently, a SID WC. I then went with a Fox F80X. FWIW, I'm only 140lbs, 5'6" and I noticed a difference between the two forks in: weight and stiffness. I've don't have any riding experiences with Manitous.
The SID WC (cut to 195mm) without the standard remote lock-out (using thumb Climb-It Control dial due to lack of downtube clearance), without V-brake bosses and with the required compression cap assembly weighed 1346g (2.96lbs). My Fox F80X bossless (cut to 195mm) with King headset cap, nut and star fangled-nut weighed 1629g (3.59lbs). The uncut bossless fork weighed 1633g (3.60lbs). The King headset cap, nut and SFN weighed 27g. So, a difference of 283g (0.62lbs)!
The SID uses 28.6mm stanchions versus 32mm on the Fox. The difference in diameter can be felt in terms of stiffness. The Fox can definitely be pushed harder into corners without wandering. The SID, when pushed, would hunt around for the corner searching for a line.
Durability-wise, I'd give the thumbs-up to my SID. It was bullet-proof through 1.5-yrs of XC-racing and training and never really needed much in the way of TLC. The Fox wasn't so good. Within the first 2 weeks, I had to send my F80X back to the CDN Fox Authorized Repair Center to have the dead TerraLogic cartridge replaced; the infamous Fox "knock" removed; and, a creaky steerere/crown/stanchion assembly replaced. I also later replaced the terrible stock Fox seals with some Enduros.
Having said all of that, if your frame is designed for 100mm, then you shouldn't go with a 80mm SID. This will drop the front-end of your bike down.
Also, should you decide to go with F100RLT, make sure you check the frame's downtube clearance. The Fox's right-side caps are very high (especially on the RLTs) and can hit the downtube when the bars are cranked to the right.
I had this problem with my F80RLT (which I sold to get the F80X - which has lower caps).
A racing buddy of mine just got his new Norco EXC 1.0 HT carbon HT (large) and he was very pissed to find that the F80RLT's caps hit his downtube on his large frame. I warned him after he bought the fork, but unfortunately, he had already cut his steerer tube. Had he known earlier, he would have gone with something else. He had to butcher the caps (file them down) to get the clearance he needed. Fox doesn't seem to care about this issue, because it's been a known problem for a couple of years with many different frames. Just something to be aware of.
