The problem with the 70* bergs is the plastic subframe. The tubular subframe on the mountain horse kit will hit the bikes plastic subframe if it pivots up at all.
Brett, what I was asking is what is the difference between the older SX subframe reducers and the new 2016 subframe reducers used with the TSS kit?
Sorry guys- got slammed by the Snow Check launch, and then finally got to take 2 days off and catch the last 2 days of spring break with my kids. That was a nice break.
Here's a few more SX answers:
With the 70 degree Bergs- we will see if there is any kind of work-around to get TSS to fit and also with frame/subframe clearance. For now, we're erring to the cautious side and saying TSS won't fit those bikes.
Older SX subframe reducers started out as 6061 hard anodized reducers, and were upgraded to hardened steel gold zinc plated bushings in m/y 2015.
For m/y 2016, the SX/ST/LT all use the same size frame bushings. So to clarify, the SX used to use oversize bushings, now the SX uses the same size frame bushings as the ST/LT always have used.
2016 TSS bushings are hardened steel, gold zinc plated. They use a rubber o-ring seal, and there is also a special nylon frame insert bushing that goes into your frame eyelets before the new bushings are installed. It's a pretty cool way to do it, reduces friction at that joint, and has tested out to be very durable.
Ride quality- This season I owned the 2015 SX 120 and SX137 kits with the new Convex rear suspension and tracks. Both my SX kits have the typical 3rd shock.
The new 2016 ST kit with TSS makes my SX feel like an antiquated technology. The new TSS is that much more responsive and reactive. It’s more plush, and feels like you use more of the available travel. I can sit down through the big bumps on the new TSS, where I would have to stand up on my 2015 SX. Videos are in production!
Here’s a few more specs:
The SX frame is shorter on the front portion of the frame.
The SX drive axle is higher off the ground.
The SX track angle is approximately 10 degrees more aggressive than ST or LT
Rear suspension is mounted differently in the tunnel to give it more travel than the ST/LT
SX suspension has a stiffer compression rate to handle the big hits that it’s designed to take.
SX tunnel is mounted higher on the rear suspension, which makes the SX kit sit approx. 1.5” higher
SX track has more tunnel clearance and does not require a tunnel kick up
SX kit is 2” narrower (frame is narrower, suspension arms are narrower, track is narrower)
SX kit is 5+ pounds lighter than ST. Weight is saved in 2" narrower parts, FLOAT shocks vs. coil overs, narrower track, etc. My gut says it's more like 8 to 10 pounds lighter. Just guesstimates.
What did I miss? Your questions and comments will help us to polish off a few TSS videos we're editing.
