    So I finally ordered a rear shock! 2013 Roco TST air

    I know I started a thread the other day, but I wanted to start a new thread on this specific shock, an see if people have any feedback. I've been looking for years to upgrade my rp23, an the volume spacers helped, but I still wanted a shock that would keep my wheel on the ground in the stutter... These were the shocks I was considering

    -Monarch plus
    -CC double barrel air
    -x fusion vector HLR
    - bikeco's custom Marz. roco TST air

    After going back an forth with Nate and Karra from bikeco an waiting months an months for stock to come in etc.. I talked to Karra and ordered the ROCO. And here's why. All my research I was finding sag problems with vector HLR and the lack of a firmer platform for pedaling. Pretty much from what I've read an what Bikeco told me the HLR is an AWESOME enduro shock geared better for the downs than the ups. When I described my riding style (everything from buff singletrack, chunky slow tech, fast chunky DH, bike park jump lines you name it, I ride it with my HD) They said definitely the roco.. So, we'll see I should have it after they custom tune it for my weight and the HD etc.. I'll post back ride reports etc...

    I too bought the Roco TST Air from the bikeco. A huge improvement over the RP23! I only have a few rides on it and am really trying to dial in my Vengeance to mate perfectly with it. But the tst is the original CTD, only with a couple more settings.

    The bikeco is awesome and they really know their sh!t when it comes to Marz shocks!

    Enjoy!

    i would be really interested in actual report vs people just saying how they love roco. i am still in search for shock for my hd, my list is same as yours except monarch. roco was always at the bottom of the list as i dont really have need for lockout, i never touch it on rp23 and having 5 positions on roco i am sure i would never use it. but again i would really appreciate actual report.

    brankulo-What exactly are you looking for in your "report"?

    And FWIW TST is not a lock out, it is Trail Select Technology. It goes from wide open, which is very plush and everything you want when pointing the bike downhill to a very firm platform, which most people like when climbing. Personally I use three settings: Wide open most of the time, one click from full platform when climbing (I like to keep the shock a little active while climbing) and right in the middle when on longer, not so steep, fire road climbs. This is exactly how I used my Fox CTD in 140 mode and it performs the same task, only the shock is far more plush in it's initial stroke and ramps up nicely while never feeling bottom out. I used to blow right through the travel on my RP23 (160) and it would wollow in it's midstroke. The Roco TST air just feels like it is the shock that should be on the bike. Mine is tuned from the bikeco and they will tell you that it is completely remapped and really no longer a Marz shock. If you are thinking of getting one I would talk to them first.

    What other info are you looking for? I will try to help you out.

    Ii guess with roco i would want to know if people end up using trail select at all in a long run or does it just stays in open position. maybe how does open on roco compare to open on rp23. i dont really see any problem climbing with open rp23, i dont ever touch that lever. i have talas fork and dont use talas lever either. when i spoke with cara from bikeco about this based on all i said she recommended x fusion. but i can also get roco and never touch trail select, but hate to pay more for function i never use like i did with talas.

    The Roco with custom tune is about $150 bucks less that the xfusion HLR stock, then add the $70.00 DW tune and the XFusion is MUCH more expensive!

    I do not touch the trail select at all on flowey singletrack or any down hill. I just like a more firm platform when climbing, but if you don't mind a little movement while climbing then you may not ever touch the TST switch. I am running about 30% sag, so there is a little movement than I like while climbing wide open, that is why I flick the switch.

    So I finally ordered a rear shock! 2013 Roco TST air

    I've got a Roco, but I never rode a stock shock. I don't think my review would help because of this. I believe the older Roco's had 5 position lever. The newer ones don't have distinct position, but still move the same amount except you can put the lever any where you want between full open & almost locked out positions.

    I love this shock & it's the custom tuned one from The Bike Company. I run it full open whenever I point down hill. Middle position most everywhere else & only full closed (locked) on the pavement.

    It's nice & plush. Takes big hits well without feeling like its bottoming, but yet when you look at the oring you can see that it bottomed on a big drop or hit. It's got great mid support.

    I weigh with gear on about 200lbs. The main chamber I set at 125psi gives me a sag of about 30%. The bottom out chamber I have set at 170psi.

    Those with the Roco TST air: Is there still a clearance issue with attaching a shock pump? For example, do you have to remove the lower shock bolt to access the air valve, or is there a fix/workaround for this?

    The Bike Company said I may have issues connecting an air shock pump, but I have the air pump that comes from Rockshox & it fits without any issues.

    The older ones are the same. I also had a 2008 Roco tst air on my Gt force and aside from the tune I would not be able to tell you the difference between the 2008 and 2013. Both levers are smooth from setting 1 to 5.

    i just checked bikeco, roco is listed at $549 not sure how much they charge for tuning it. vector hlr they have listed at $599 no tune. so $50 difference . if it was $150 cheaper i would go for it all the way. am i not seeing something?

    Brankulo, that is list price, bikeco sells them for 450 plus shipping fully tuned. Atleast that's what I paid. I bought it with custom tune, an new bushings plus shipping and it came to $491. As someone already mentioned, they may as well call these shocks "bikeco tst airs" It should be here the end of the week.. can't wait...

    $450 is about what I paid too, which for a custom tuned shock is a pretty damn good deal! No brainer in my mind.

    that is very decent price. i could have ccdb air for about same price with discount coupon so there goes my dilemma again.

    hy all,

    I use the Rocco Air RC World Cup (2013) in my HD'2012 (size M) and THERE ARE clearance issues - big headache after bought it and try to assemble ;-)

    But "RESET RACING COMPONENTS / Air Port EVO" fits exactly between valve and frame and moreover you can adjust the air presure of the shock excellent -
    better than shock pump !

    Rocco - huge improvement !

    Which way do you have yours mounted? Mine is mounted with the can in the rear and I have no problems with the Fox Digital pump (which has a longer screw valve portion than the regular Fox pump). If your pump has a short screw valve then you may have issues getting your finger around it.

    Hy - same way as you - BTW: there isn't a different way for
    that damper....


    I "reused" my old damper pump ;-) short/wide "attachment" to the valve. You see not so much space between frame and valve - but the reset thing helps me.

    Got my 2013 roco TST air shock in the mail last night. I ordered it with new bushings so I slapped it on, an went out to the local trail system by my house, which is one of the more technical areas around.. not alot of big hits, but alot of chunky baby head and sometimes sharp headed rock gardens. Has alot of short climbs and short fast downhills.

    First, the mounting. I ordered with new bushings so it was all preassembled, I just took out the bolts on the rp23 an replaced. Shock pump (scott shock pump) worked perfect, no problem getting to either of the air valves.

    second, set up.. I'm 155-160 lbs when I'm on my bike. I set air pressure at about 90psi and bottom out was preset by bike co at around 150. Gave me about 30% sag give or take (didn't measure, was in a hurry to ride)

    Third.. the ride. Small bump compliance is far better than the rp23 with spacer. I was purposely hitting everything that was on the trail to see how it would handle it. Before it was soft in the front with my lyrik an somewhat harsh in the rear with my rp-23, now it's the opposite, it's softer in the rear and harsher in the front. I literally feel like I'm riding on a coil shock.
    Climbing... rear tire definitely sticks to the trail better on technical climbs (which there's many where we rode) an the only thing that didn't allow me to clean all the climbs was my early season weak legs.
    Cornering.. at speed, it corners better too, more confidence on chunky corners cuz the tires on the trail not bouncing around.
    descending... what can I say, I can pump this bike so much easier now over the terrain and descended like a champ. biggest hit I had was probably 2-3' an didn't come close to bottom out. I still need to play a little more as I probably only used 80% travel last night.. maybe I'll wait till I have some bigger hits.

    Overall, this shock is a huge improvement so far over the rp23 with the spacer. Only thing I will say.. be careful when your manualling for the first few times with this shock on the back, as it feels so much like a coil the front end comes up way easier due to how plush this shock is at full open. After 1 ride, I'm glad I made the purchase, I'm sure it'll just get better as I ride it more and I will do another report after a few more different types of rides.

    FYI, bike co ships these now as an almost non branded shock.. you will not find a marking on it.. that matters to some I'm sure.. and also, I mounted the same as the pics above..

    For checking on bottoming out you need two O-rings. The stroke is 2.5" but the shaft shows more then that so it's really tough to tell if your getting full travel or not.

    What size O-rings? Also, I'm assuming to set the sag correctly, you have to put an oring at 2.5 inches and then do 30% of that? So it would be 3/4" of sag for 30%?

    Sorry I don't know what size O-ring. A zip tie will work. You don't need 2 O-rings to set sag, 1 will do & yes 30% = 3/4".

    Hey Manchvegas, can you comment on how it pedals? How about the difference that the TST settings make? I'd love to hear more...

    Ok, so I've got about 60-80 miles of hard riding on this shock now. I haven't really played with any of the settings.. I mostly set the pressure an forget it. I'm running about 28-32% sag..

    Technical xc/AM riding I have been leaving the shock full open for really good small bump compliance which is definitely improved over the rp-23 with spacer.. It seems to pedal just as well as the rp-23 as well, no noticable difference in pedaling performance.

    smooth trail On really smooth trail or extended climbs I have been finding myself turning the TST setting to what seems to be 75% open.. (100% being full open) an it climbs very well. and the setting is very propedal feeling.. only it's a very linear adjustment unlike any fox... it's a linear knob that you can go from probably 20% (mostly locked out) to 100% open. I've been mostly using it on long climbs, fire roads, or pavement an it works good.

    Descending... I've finally gotten the chance to take this down some real chunky DH sections an I have to say, it's far better than the rp-23 as the rp-23 would bounce all over the place as if it just couldn't track fast enough no matter how you played with rebound.

    Cornering.. I think this is one of the most improved things for me since I put this shock on... I'm actually trusting the bike ALOT more now in highspeed cornering, as the rear end seems way more glued to the trail than ever before.

    manualing.. maybe alot of people don't think about this as they are a sit and pedal kindof rider.. but it's a main skill in mountain biking that is often not used by beginners etc.. an I have to say most bikes other than a coil sprung rear end make it hard to do anyway.. with this shock, it feels like a coil in that I can just stand up at speed squat the rear end and manual over things like never before..

    Well, that's pretty much what I've taken from it so far.. loving the shock and glad I finally upgraded the rp-23...

    I have been on the shock for quite a few miles, a couple hundred atleast. I really like it.. I didn't think I'd use the lockout but it's actually really nice for long extended climbs. I leave it open all the way for technical stuff so I get all the benefits of the suspension an traction. buff trails I kinda leave it 2 clicks in for a little firmer feel and better climbin on the quick up an downs an then I lock it out complete on fire rode etc.. I have since bought a xfusion trace from bikeco for a ripley build an they have been great to deal with.. an the shock has been great so far.. as far as long term... I dunno, only had it for about 3 months now..

    Great thread! Just got a 2012 Mojo HD with the Talas 36 that I'm having The Bike Co convert to Float with the pro tune. Found that I don't really use the trail adjust function and really want the small bump compliance from the Float along with the consistent compression, dampening, and ramping. The Talas suffers from too much stiction no matter how I adjust the settings. I'm having them slap on the TST R as well. Super stoked to feel the difference as I am not a huge fan of the RP23. The Bike Co......love that place.

    anyone knows how Bikeco limits travel on this shock? i got version for hd in 160 mode and noticing the clearance for rear tire is more than enough. would like to add tad more travel if possible. there is about 1" left on shaft that doesnt get used so there should not be problem with short shaft.

    are you running 140 or 160 mode? i am thinking i have received wrong size/stroke length shock from them.
    i am in 160 mode and the shock has 2" stroke, leaving 1" unused. 2" however is only around 130mm instead of 147 according to my calculations. can anyone who has 147mm roco measure stroke lenght? i am on regular HD, not HDR
    thanks

    can anyone tell me exactly what the bikeco tune is?
    sounds like they shorten the eye to eye on the shock as well as limit the stroke.
    i would prefer to get this from marz directly as i am in vancouver, bc.

    they dont shorten eye to eye. i am on 650b hd, the shock came with 2.5" eye to eye. there is however thick shim inside to limit the travel. so if you need to go back to 26" wheel just pop it out. they also set ifp and maybe use different oil weight based on your input.
    the shock is great btw.

    thanks for your reply. the 2.5" is not the eye to eye measurement, it is the stroke length, which as you said is limited.
    The measurement i am after is from the center of the bottom shock mount to the center of the higher shock mount, which is the eye to eye.
    the shock is stock at 8.5" eye to eye but according to many they have shortened this to make the bike slacker/lower.

    yeah, sorry, eye to eye is still 8.5", no change there. stroke is limited for 650b conversion per your request. you can tell them what rear tire you planning to use ant they will maximize the travel based on that. i doubt they do shorten eye to eye, but they are great to deal with so give them a call and ask.
