This listing is for TWO Ohlins rear shock adjuster tools used to adjust preload on shocks without a hydraulic preload adjuster canister and with 'large' adjuster rings.
Please take note of the position of the spanners in picture 1 of my listing. Put both tools in one hand, then bring the handles together. This should unlock the adjusters.
The tool is tested to work well beyond the manufacturers torque figure for preload adjustment. If the tool starts to deform your adjusters are seized and you need to seek specialized advice.
Any questions please contact me.
