The geometry on these is quite similar. I know no-one has really ridden the 140 year, but it might be nice to start this discussion. I was about to pull the trigger on the 130LR, and still probably will, but after reading reviews and looking at geos I am guessing we can posit the ride quality differences on these bikes before anyone really rides them back to back.

Who knows, maybe someone from Yeti will chime in?

For comparison sake I will be looking at the SB130 TLR in a Large and a SB140 T2 in a size Large:

SB130 LR - Large

Reach: 476
Stack: 628
Top Tube: 627
Seat Tube: 450
Seat Angle: 76.5
Head Angle: 65.1
Chainstay: 433
Wheelbase: 1234
Standover: 734
BB Height: 341
Fork Rake / Offset: 44
Fork Length: 567
Wheel Size: 29"
Front Travel: 160mm
Rear Travel: 137mm
Shock Size: 210x55mm

Weight: 30.7 lbs

SB140 T2 Large

Reach: 480.1
Stack: 609.9
Top Tube: 621.5
Seat Tube: 450
Seat Angle: 77.0
Head Angle: 65.0
Chainstay: 433
Wheelbase: 1232.9
Standover: 712.3
BB Height: 339.9
Fork Rake / Offset: 37.5
Fork Length: 567
Wheel Size: 27.5"
Front Travel: 160mm
Rear Travel: 140mm
Shock Size: 210x55mm

Weight: 29.05

Any major differences in build (SB130 listed first):

Wheels (DT SWISS CUSTOM EX1700 30MM vs DT SWISS M1700 30MM)
Brakes (SRAM CODE RSC vs SRAM G2 RSC)
Rotors (200/180 vs 180/180)
Front Tire (MAXXIS MINION DHF 2.5 EXO+ vs MAXXIS MINION DHF 2.6 EXO)
Rear Tire (MAXXIS MINION DHR II 2.4 EXO+ vs MAXXIS REKON 2.6 EXO)
Bar (Yeti 800 vs Yeti 780)

Everything else on the bike is the same.

SO

A FEW THOUGHTS

  • At least part of the change in the geometry between the two seems to be that the SB130 is actually a "screwed up" geometry version of the SB130, and the SB140 was built around the longer travel so it had its geometry "fixed" to handle those numbers.
  • SB140 is substantially lighter with a similar build. Is that primarily the wheels (bigger) and EXO+ tires?
  • Really the preference probably comes down to wheel size. Which sucks because I prefer 27.5 in the back and 29 up front.

All I hear is blah blah blah blah wheel size. Seems like that's about all that matters, right? I'm not sure how you get to "screwed up" anything. They're new designs. I'll assume that they're what Yeti wants to sell.

Just pick a wheel size...and be a dick about it! Seriously?!? The Yeti is the easiest to mullet due to the 20mm difference front/rear. SB140/140...BOOM, done.

As far as weight goes... Have a look at the weights for the tires. There's a huge difference between them. The stock LR wheels are boat anchors. The 2019 sb130 x01 race build was 28.3lbs.

Aside from that, I don't think it's great to compare a 29er to a 27.5. Ever. The question is, do you want a 29er or a 27.5?

Rode my 130lr with 27.5 wheels this past weekend and can report that it works.

i didnt notice any negatives. the cranks were low but it was not very rocky

easier jumping and turning

I have ridden SB130 and now own SB140. I can tell you definitively after riding the M and L SB130 and the M SB140 that:

1)Climbing is a draw

2)The SB140 is far more intuitive in the air and easier to get high than the 130 by a sizable margin

3) The SB 130 is faster on rough terrain, no questions--it's a "mini enduro" bike.

4) Both pedal very well out of saddle

5) SB140 is way more quick in the turns and very intuitive to flick/drift. SB130 (M) wants to grip at all costs and requires slightly more effort to turn but is no slouch in tight terrain.

I'm 5'10" and live in the upper midwest. I originally rode the SB130 in a size L and was not a huge fan. LBS loaned me a size M SB140 and it felt like superman's cape the moment I rode it. I bought one, took it to Copper Harbor and crushed terrain I never thought possible. Fast forward two weeks I rode the size M SB130 and really liked it. It's not as fun as the SB140- it just puts smile on face every time I ride it- but it does seem much faster over rough terrain. I currently own a 2017 fuel ex 29 9.8 and have ridden the SC high tower, and out of those three the SB130 is my favorite 29er...but at the end of the day the SB140 just has that something that gives me the fizz every time I ride it.

They are both very fast bikes. If you want a slant toward speed and stability get the 130, if you want a pop machine get the 140. Both are great.

Thanks....great info. I've had (2) SB5's and loved them, especially the playfulness and FUN factor going down. I'm 5-8 and demoed a pimped out medium 130 and loved it going up. Most comfortable climbing position I've ever been in on a bike. Going down was a let down for me and very meh. It might have tracked/gripped well as you mentioned but it wasn't playful, poppy or FUN in the air....for me. I'll be demo'ing the 140 in a few weeks.
