Terrific video. New dvo user and this is enormously helpful. From the other side of the planet... Sincerely thanks!
Thanks! Awesome you make these videos! I'm glad I found your channel! :)
Great video keep them coming
Thank you for the excellent information.
Thank you so much for helping out with your vids! 👍
I still wonder, when I would choose to top up the OTT reservoire and when to add bands in the negative chamber. It's kind of the same for me 😅 I'm at the point, where I added 1 negative band and topped up 25% of the OTT.
I ride a 145mm Ripmo (V1) with a Topaz T3 and weight about 162lbs (81kg) in ride-ready outfit.
Thx 🤙
Hmm. Metric is confusing for yall Americans. 162Ibs is 73kg? 81kg is 178Ibs. Btw 2.2 is your factor lol I'm 175 kitted.
I'm super light at ~140 with a light kit, and have the Gen 3 Topaz. Having a hard time using much travel, even on some pretty rooty rocky stuff. The sag is at 25% where I usually like it, but it's a bit wallowy in the beginning travel. My goal is to stiffen up the beginning travel to add a bit more support, but also be able to use more travel on rougher stuff.
Think I'm best served by adding a band or two to the negative chamber, lower pressure a bit, and see how that goes?
I just started messing with customized spacer sizes in the positive side. I found running two was too stiff in the mid stroke so I sanded one down and polished it up to be roughly half the size of a normal reducer. I still have more testing to do with pressures to see how 1 and 1/2 spacers feel against 1 or 2 but so far I'm not unhappy with it.
Excellent video! I'm riding a Stumpjumper Evo with Cascade link. Stock this bike is very linear. The Cascade link made the bike noticeably more progressive but I'm looking to get a little better mid stroke support. I have a Topaz with 240psi at 30% sag with 190PSI in the bladder, 3 bands in the positive chamber, and none in the negative. Do you think trying a band or two would help with this? I feel if I add another band to the positive chamber the bike is going to ramp up too hard towards the end of the stroke. More air in the bladder made the overall stroke more firm and the bike felt harsh. Maybe I should just try running a little less sag? Thanks for the insights!
Even with that link you need to run 23/25% sag. Id take all the spacers out, go to 23% sag and add one spacer at a time if needed
@@jessedvo4919 Thanks for the insights! I'm going to give this a try and do some bracketing this weekend to see how it runs.
Bonjour , je roule sur un EVIL INSURGENT avec un TOPAZ2 , SAG de 30% (235 psi) , j'ai 2 bandes sur la chambre positive et 0 sur la chambre négative. Je trouve que j'ai un phénomène de pompage dans les montées , parfois très marqué dans les forts pourcentages. Pensez vous que l'ajout de bande sur la chambre négative peut limiter ce problème ?
Thanks
Hi, I’ve got the topaz 2 on my giant reign have someone use my bike and ride it over jumps etc with the shock in firm setting! To my delight I found the firm setting is now no different to fully open and now has a squishy sound to it under compression, I’m guessing something not to good has happened but is there anyone in the Auckland/north shore area you recommend taking it to so it can be fixed cheers Mitch
Take it to Finn at Lewis and co.
What was the diagnosis of your issue? I have the same problem and am about to strip down my shock
He jesse. Do you have to take all the pressure out of the bladder when you take the air can sleave off?
The bladder should stay pressurised but yeah definitely take the air out of the aircan haha
@@jessedvo4919 i did a small service on my topaz t3 air the other day. I took the air out of the bladder, was that a mistake? And how will I know if anything happened by that? Thanks!
@@lasseboejle it’s not ideal but just pump it back up. And definitely don’t ride it like that
@@jessedvo4919 thanks for your answer! :) I hope nothing happened. I did remember to pump it up again. I found a walk through on CZcams, and he took the air out of the bladder. Probably because he also serviced it. I ain't gonna mess with the bladder :p
Hello
I need a piece of advice. I am 270lbs. I have 3 bands on the positive and 250psi, but I have 40% sag. Do you recommend some other setting?Topaz T3
Alexandros Orestis how many bands in the negative? 40% sag is far to much so getting you back towards 30% will be ideal
I would strart with putting 2/3 bands in the negative chamber and putting 250psi in and re testing the sag
JP Tuning Thank you for the response. I have 3 bands on the positive. What’s the difference. I try to understand but everyone explained to complicate.
JP Tuning I don’t have band on the negative.
Alexandros Orestis bands in the positive chamber support bottom out and bands in the negative build up initial support so everything from 0/30% sag is affected by the negative volume. The smaller that volume is the easier it is for 250 psi to support your body weight.
JP Tuning the Topaz T3 doesn’t take 3 bands on the negative, so I put 2. I am gonna let you onow
Why do you like so much progression in your topaz?
I try and test all extremes
Hi ,what are your Instagram and Facebook accounts? Thanks
