Another question, I apologize.

I've had some troubles with the superdeluxe air I bought and I will return it, I think about getting a superdeluxe coil.
I cannot find it in 210*55 so I will take the 210*50.

Here is my supposed spring calculation:
-

What do you reckon ? For an all mountain/enduro use, should i go on the firm side with 650lbs ? The shock has a firm switch for climbings.

Edit: I might have found a 210*55, here is the calculation:
--
550lbs seem good?

Thank you Smile

Why 210x50? Here in Europe there are plenty 210x55 coil shocks. You want the full 150 travel instead of 140mm travel.
I would go for the 550

I found the dvo jade which has no french after sale service, and fox shox which are a bit too expensive for me. The superdeluxe seems like a good idea but I cant find it in stock anywhere in 210*55. I agree that I should wait to find it in stock to get 150mm.

I also found canecreek but it has too many settings, from a past experience with a fox 40 I dont like having HC, LC, HR, LR.. just compression + rebound and a firm setting for climbing is better for me.

Which model did you have in mind?
I agree for the 550lbs I think I will go for it

I have the Bomber CR.. Simple but does the job. And maybe a 600 spring because it's a trail bike.

I saw it but no lockout quite makes me wondering.. does it not make it less efficient ?

Also, do you know bushing size for the jeffsy ? (current one)

You need to find the proper size shock. I would not settle for the wrong shock stroke/length just because that's all you can find. Hold out or find a shock that's proper, you might regret it if you settle.

When the Jeffsy came out in 2019 it actually came with a 210x50 shock. It just makes it 140mm travel instead of 150mm. The geometry is the same as they are both 210mm in length.

Looking to put a 160 mm travel fork on a Core 3. What is the steerer tube length? Do I need to take my fork off to measure?

Just measure from the outside, from top of crown to top of stem
Add 0.5 to 1 cm to be on the safe side and/or if you want to be able to play with the spacers to adjust the stack

Turn handlebar 90 degrees so you can measure more easily lengt from the crown to the top of steerer tube...
