2022 Sentinel air shock vs coil?

So I’m about 3 rides in on my 2022 Sentinel alloy. 1st 29er and I’m really impressed with the extra speed downhill. Broadly the air shock seems quite good most of the time - although I’d say it goes into the mid range a bit easier than ideal.

My last bike was 150mm front / 130mm rear travel - but it had a Fox DHX2 Factory coil on it. That sat up better in its travel I’d say - and had every adjustment going on it - hsc / hsr / lsc / lsr / climb switch.

I’ve just ordered the token tuning kit for the air shock I’ve got - it’s a Float X Performance Elite so has lsr / lsc adjustments, plus a climb switch and the ability to add tokens.

I’m wondering about a coil - but the bike already weighs 34lbs give or take and I don’t want to add too much more weight.

Has anyone used the same air shock as me and then gone onto coil instead on the v2 sentinel (alloy or carbon) - if so was it a good swap / does it avoid bottom out ok?

Wondering about the Cane Creek db coil il as that’s pretty light for a coil shock with the Valt spring. Not sure if I’d miss a piggyback or not - I don’t do anything longer downhill than the stuff at Bike Park Wales.

If you want a little more coil feel with the bike without going to coil, I would look at the Cascade Components Linkages for the Sentinel. I have one on my bike, and the suppleness has improved, similar to a coil.

Will do - I think the main thing is the mid range support I’m missing at the moment. The bike feels nice and plush with the air - just perhaps it feels like the mid range is a bit soft. I’ve found this with air on both my last 2 bikes too. It’s not awful - just a feeling I have sometimes. It’s particularly on big compressions and on some steepish climbs. The DHX2 factory on my last bike just felt like it had a nice bit of support to lean against.

I’m going to play around with pressures and tokens for the next few months and see where I get to.

As someone who went though this on a Scout, a Super Deluxe fitted with a MegNeg will give you a linear coil-like mid-stroke, with the added bonus of more pop. It's not going to match a coil (or even an X2) for small-bump compliance, but you still get a progressive end-stroke.

The thing is, that progressive end-stroke is not necessary on a bike like the Sentinel. If you're already looking at buying a new shock, it's hard to beat the overall performance of a coil. If weight is a concern, however, I thoroughly recommend picking up a used Super Deluxe and throwing a MegNeg on it.

I’ve had a few more rides on it since I originally posted - I think it was just getting used to going from the extra support of the coil to an air shock. Actually it’s working pretty well - it’s plush over small stuff - it resists bottom out and I don’t think it’s giving up too much mid stroke too easily.

Still would prefer a coil I think - if they make a trunnion Cane Creek DB Coil iL in the right size that would be perfect as barely any heavier than the float x even with the weight of a vault spring.

That's good to hear that a bit of time and tinkering has made you appreciate what you've got. Since it's PB, you could always troll the BuySell for a good deal on a coil.

I was super excited to see Cane Creek announce trunnion versions of their DB Coil iL... only to find it's 185mm only. Mad

Yeah that’s annoying it’s only 185mm eye to eye options. Guess I’ll just ride the float x for now rather than add a chunk more weight with a piggyback coil.

I rode a coil for years on my previous bike so when I got the Sentinel (carbon) with the X2, I thought it was good but never as good as before. So I have just installed a Push…haven’t tested it yet but just around the block you can feel the differences on how much more plush and supportive it is, with much more difference between modes as well! But it was around 300gr of weight penalty and even worse on the wallet!

Ive now had 2 good rides on the Sentinel on the Push (also new 38's)...the bike is much better...so much more traction, much more composed and settled and I can keep much tighter lines than before. Took it around my usual loop where its a good testing ground and I could straight away feel the differences. Its also more quiet. A little bit harder on the climbs (also had a new front Assegai and rear Big Betty). For me it was an improvement.

Cool to hear the shock experiences. I’ve also been chatting with W guy who has the alloy sentinel and swapped out the Float X for an EXT coil and loves it.

I ended up leaving the tokens as they are and upped the pressure to 200 psi (I’m 75kgs) - this is the best compromise so far. It sits up much better when pedalling and doesn’t blow through the mid range so quickly / so easily. I think token wise it’s just about right - I’m not seeing any hard bottom outs but the rubber band is getting right near to the bottom of the stroke / has occasionally fallen off the bottom on big trails.

But it has lost some small bump plushness - on the steeper / loose / tech stuff it isn’t finding the grip it had before when I was running it softer.

I’ve got a Cane Creek Kitsuma coil arriving today with a 400lb Valt spring. I don’t think the lower hardware will arrive until later in the week though so a trial fit will have to wait. I’m hoping I’ve ordered the correct weight spring - online calculators suggested 380lbs and I think I’m heavier on my rear shock than the fork with my riding style.

I measured up the existing Float X and compared to the measurements of the Kitsuma and I think it should be fine for clearance to the downtube on full compression but I will check. I wonder if it’ll hit the water bottle though due to the big (ugly) dials - I might have to try and slide that further up in the frame with a di2 external battery mount.
