Hey guys,
I want to buy a Vivid R2C for my Big Hit 09. But I am not shure which Tune to take. Mid or High ?! I took a look at the graphic shown on the Rock Shox homepage but the Big Hit is just at the edge between Mid and High. If it is helpfull: I weight 90kg

Are there any experiences ?

Pls post a link to the page and shock/wheel travel ratio. Also what spring you use.

That is the graphic I had been talking about. At the moment I use a 500lbs spring at the Fox Van R

The 2009 Bighit has a 8.5" x 2.5" rear shock and 7.5" of travel.

Assuming you've not modified it in any way, you're looking at a leverage ratio of 7.5/2.5 = 3.

On the chart above, that puts you in the C tune.

 

[jekyll991]

is it completely dependent on leverage ratio or should weight be considered too? I'm going to be trying out my brother's vivid air with the mid tune since my bike has only a slightly higher cr (2.8) but I only weigh around 120lbs.

that was my first thought too but then i heard of many people using tune b and being happy with it so i was confused. i think i´try tune c just as i am not the lightest

 

[cjm102]

When they are talking about tune a, b and c is this the dampening tune or air can ramping? can you adjust the tune if you get the wrong one for your bike or change bikes with a different leverage?

 

[Udi]

A,B,C are the damping tunes.

Exxun / jekyll991 -
Body weight definitely plays a part in which tune you'd pick, because the damping essentially controls the spring, and as rider weight varies, so does the spring rate.

So if you're lighter, you'd err on the lighter side of the recommendation, and on the firmer side if you're heavier.

 

[Vrock]

Body weight is very important when the bike in the middle of two tunes, and that happens a lot of times too.

It also depens on prefferd suspension setup and riding style.
