I have a 6fattie 2017 specialized stumpjumper with 135mm of rear travel I was wondering if it would be good to put a coil that fits a stumpjumper for better traction and also increase the travel in the rear if possible to 140
Thanks

Yes, it would be a great idea. The Stumpjumper is reasonably progressive and plays well with a coil. However, it has a proprietary shock mount, so you'll need a shock that's compatible. As of this writing, I'm not aware of any coils that have the type of mount you need. BikeYoke makes an aftermarket frame piece that will fix this, but at EU$105 it's not cheap. However, it's worth having if you want more shock options.

It's also worth mentioning, that in order to get a little more travel (via a longer stroke), you have to use the BikeYoke. As stock, your Stumpy is 197x48. This 197mm eye to eye is basically only exists for Specialized, so there aren't any other stroke options available. However, by using the BikeYoke piece, you end up with a 190mm eye to eye, and then you have access to shocks with a 51mm stroke (like these) that will get you to about 140mm out back.

That said, you might consider a Specialized compatible piggyback air shock in place of a coil. You won't get longer travel this way, but if you're running an inline shock (no piggyback) then you'll be getting so much more performance that you'll feel like there is more travel out back than before. There are good offerings from RockShox and Ohlins in that regard, and they'll give you a great upgrade over any inline shock you might have. However, if you're going this route , I'd point you at the DVO Topaz. It's a very supple, very linear shock that comes with the proprietary stanchion mounting you'll need for Specialized bikes. I've been riding one on my Jeffsy for about 18 months and I'm no longer tempted by coils; it's truly that good.

Thanks the thing is i don’t thing a piggyback will fit because I have the swat system and I barely fits a in-line with a water bottle

The Ohlins will definitely allow you space for a water bottle. You could also run a smaller water bottle, something like a 12 oz. Unfortunately, tradeoffs are a big fact of life for mtb....

Oh! You could put a ziploc full of water in that SWAT box.....lol

Nice idea for the ziplock but I will consider the Öhlins or the bikeyoke and will probable put a rockshox coil with a grip remote lockout on the stumpy

Do you think it would work to put a 160 fork on the stumpy maybe like the new lyric rc2

I changed the air shaft in my Pike from 150mm to 160mm on my 2016 SJ Elite. Changes the geo sligthly, you get used to it within like 5 minutes of riding though.

I wouldn't say it's worth a new fork though. I did mine because I was servicing it, and the air shaft is easy to replace/ is only ~$30. Tbh the riding isn't much different.

I had more results/ different feel playing around with bottomless tokens.
