Rear shock confusion!

[RichardGB]

Hi all,

I'm very confused as to what shock I need for my 2018 e160.

I'm switching over to coil from my X2 and I know I need 205x65 turnnion mount.

What I don't know is what extra hardware I need if I go for a Rockshox or a DVO?

What length spring do I need? I know I need a 600lb spring rate.

The answer would be to take it to my lbs and have them figure it out but I'm trying to keep to a strict budget.

I've seen a bunch of folks have converted theirs and scoured the threads but I'm still not clear.

you will need lower link hardware unless new shock is exactly same size. no hardware at the trunnion mount. Consider an EXT - they ship with two springs as standard where as most other brands have springs as an extra. I am trying myself to relate my air pressure to a coil spring rate.

Thanks for the info.
I've looked at the EXTs and they're a very nice looking shock.

Spring rate is tricky. There are some good threads on here which have helped but struggling to find what the leverage curve is for the e160. I'm going to try for a progressive rate spring which should match the air shock as I'm assuming it's got a linear rate.

Hopefully, I ca. Find a suitable progressive rate spring if this ends up being wallowy.

The width of the hardware will depend on the frame and the diameter on the shock model, but most seem to run 12.7mm (J-TECH HD Mount Kit 1/2"). Check out J-Tech or TF Tuned. They have good info on their site and are always really helpful if you give them a call. For spring length, the manufacturer will (usually) spec the range of shock stroke the spring will work with. For instance, an RS spring can be bought in 57.5-65 of 47.5-55. If you go for an inline shock like the Cane Creek, note that they will need a smaller spring than a piggy back shock, as the there's physically less room for adjustment.

I run a progressive rate CC spring on a CC DB IL. It's works great, but the bike is very linear (Starling Murmur).

The EXT is amazing (my GF has one on her Starling). If you buy from Mojo in the UK, they will tune it your weight / riding style / bike. But obviously, they are very expensive.

For spring rate, I paid for the advanced calculator from TF Tuned. Also, there was a recent article on PB with a formula and when I worked it out that way, it was very close to what TF had recommended (497 VS 500).

Cheers for the info. Sadly, I couldn't get the shock to fit due to the spring bumping into the frame. I'd have had to run a tonne of preload to get it clear.
I'll stick with the X2 for now and maybe upgrade that to the newer one at some point.

Or I could just lose some weight so I don't need to run 300psi...
