SB100 threaded rail conversion kit

Well, that did not last long...from Yeti Facebook posting

Those little carbon SI mounting tabs have to take an awful lot of stress. I wonder if the new threaded design puts more stress on them, making failures more likely.

Yeti makes more money selling a complete bike than a frame only. It's their way to keep their profits up.

You think they make thin margins on the frame only?

I'd argue that they make higher margins on the frame, but more revenue on completes.

Agree those carbon tabs holding the SI in place appear undersized for the load they need to handle.

I think our best bet is to watch for this issue with SB115 owners since they are using the updated SI hardware. If there is going to be an issue then it should show quicker on the SB115. But who knows, maybe the SB115 frame has been reinforced in this area.

We will need to wait and see if Yeti has once again solved one issue only to create another.

I was thinking about this more. In the original design of the SI, there were 2 thru bolts. When they switched to 4 separate bolts, that probably increased the stress on the mounting tabs since the bolts can now flex independently. And in the latest design, this stress is probably increased yet again, since the threaded screws tie the SI more tightly to the rear triangle.

Could you potentially swap out the Switch Infinity and the linkage and turn your SB100 to a SB115?

Could you? Yes

Will Yeti be cool and allow us to do this? No.. the sob’s are being difficult and not selling any of the sb115 hardware currently.

It is what it is I guess. Gotta sale more bikes.

Honestly, just slap a 130 on the sb100 and you’ll be damn close to a 115. Not a huge difference. It’s just a slight bump in rear travel to sale more bikes.

sb100 Max Tire Width on 25MM Wheel

I'm looking to move up in tire size to gain a little more stability. I've searched these forums without finding a great answer.

I'm running to the stock 2.3 Minion/Aggressor combo on the DT Swiss XM 1501 Spine AL 25MM. Would I even notice going to 2.4s? There aren't a lot of options at 2.5. Would 2.6 be pushing the wheel width? Would the Fox 34 Float SC FiT4 be ok with wider tires? Thanks!

I run mine with 2.4 Dissector front and 2.4 Rekon rear on 30 mm internal width rims and it's added some stability and control to the bike compared to Ardent Race 2.35/2.2 on 27 mm rims that I had before. I don't think you can fit a 2.6 in the rear.

I have been a long time lurker on this forum, but never posted. I ride a 10.3kg SB100 which was a warranty upgrade from Yeti when my ASR Carbon cracked.

Based on the previous posts about the SI linkage tabs cracking I thought I would check mine and found this....

The frame only has 4500km on it, and a significant amount of that has been on the road as I had a nasty injury in 2019 which took many months to recover from.

I've now cracked a lot of Yeti frames (the warranty service has always been fabulous), but never really cared as I was riding the bikes really hard. This one, not so much.....

Do you have the original (V1) SI bolts, the first attempt at a fix (V2), the next attempt with nylock (V3), or the latest attempt with threaded bolts (V4)?

The V4 bolts shouldn't loosen up like the V1-V3 bolts. However, that means more stress on the carbon tabs that hold the SI. To my eye, those tabs look pretty small for all the stress they have to take (vertical and lateral).

Unless you are a carbon specialist or engineer, your eye doesn’t mean much.

I have the naked carbon frame and have had zero issues. To me it looks like paint flexed and cracked. Has anyone confirmed that the carbon is actually cracked? I have only seen the issue on the painted frame thus far.

I know it is not the original one piece V1 bolt, or the latest threaded V4 bolt version. How do you tell the difference between V2 and V3?
