Posto anche il commento, purtroppo in inglese, dell'autore del video dove in un forum USA descrive la procedura della rimozione e commenta dicendo che per prevenire il raggiungimento del limite di usare una pressione più alta del raccomandato (nel suo caso da 135 a 175 psi) e che auspicherebbe un riduttore di dimensioni più piccole (per assurdo suggerisce in un altro post di usare un tappo di bottiglia di plastica tipo spumante) per effettuare una messa a punto più fine.
"That was indeed my issue also. I was running 130-135psi as registered on the shock pump and that put me right around 30pct sag.
Never got more than 85mm of travel got 90mm once but that was running 125psi and on two consecutive big hits.
Pulling that spacer could NOT be easier.
1. Get ALL air out of the chamber.
2. 24mm socket and pull off end cap
3. Take a 6mm bolt (headset top cap bolt) thread into bottom of travel spacer (it will be obvious).
4. Grab with pliers and gently pull out the spacer (note, it sits about 17mm into the bottom of the fork in case you want to put back in)
5. re-install end cap.
6. Set air pressure (I found about 175 worked well)
I really think you will find you get 90-95 mm of travel and have a much better bottom out feel. I think bigger riders will really enjoy the extra air in the chamber, lighter riders may end up wanting to reduce some volume. I suspect I wouldn't mind reducing it just a shade from here, but not a ton.
Try it, see what you think.
What I'm interested to know is if we are OK to run more travel. I wondered what the difference was between the 90mm and 100mm 29er lefty's as both use the same number of spacers and same chassis. Looking tat the shock parts, the dampner is slightly different in part number. So, wondering if adding 5-10mm of travel by reducing a spacer could lead to blowing up the dampner. Because I really think I could run 110. "
