Anyone riding a DW spot with a low volume rear shock?
1 - 20 of 27 Posts
When I designed the suspension for the DW Spot, I speicifcally developed the Leverage ratio to let riders choose between the FOX XV can, The standard can, or a coil spring. This was something that DT and I talked about quite a bit during the 5 Spot development process. Turner riders have historically been "tweakers", they like to modify and change their bikes. We wanted to accommodate that, and one way was to design the bike with a leverage ratio that works in harmony with the dw-link anti-squat curve, and performs well with a variety of spring and shock options.
I've done a great deal of testing with many variations of shock and spring.
I recommend the XV can for more XC oriented riding, the standard can for more aggressive XC riding where you have bigger drops and need bottom out resistance, and the FOX RC4, Rockshox Vivid, or Cane Creek Double barrel for the most aggressive riding. FOX also offers air spring spacers that let you shim the XV air can to get something in between the XV and standard air cans. The bike can be as tunable as you want it to be from a spring standpoint.
Hope this helps,
Dave

Thanks a lot Dave !
:thumbsup:
That is the exact explanation I was looking for
I will try the regular can as I tend to spend some time in the air from time to time, otherwise this bike works Great with the high volume can!
Thanks again.

It`s much cheaper, to fill the XV Sleeve with a few PVC shims... you should give it a try and if you don't like it, go for the Coil.Saar G7 said::thumbsup:

It all began on Saturday when I launched a slope to slope approx. 4-5 feet high and despite a smooth landing on both wheels, the rear shock bottomed out, nothing harsh but very distinctive to the familiar user...
So I posted a question about a small volume shock.
I Just got back after riding a couple of hours on a regular volume shock (swapped cans with a friend). The initial stroke is plush and is very progressive as you near the end of the stroke. I had to lower the pressure about 10 PSI to make it feel as plush as it was before.I lost traction is places I have never lost traction before and used significantly less travel,
The high volume can was a good match to the Float 36 R while the low volume can was a bit too progressive for me. it felt like I was riding a short travel bike.I guess I got used to the plush and bottomless feeling of the high volume shock. I love the way this shock works, however I needed some bottom-out resistance. So I swapped cans again and put a shim inside the top part of the shock in the cavity \ "dead space"like I did with the regular volume rp23 I had on my Sixpack which have proved to be very effective.
The only thing that is worrying me is that the shock has some "stiction" in the first couple of milimeters of the travel that goes away when the shock is compressing deeper into its travel. I can t remember this happening before and I noticed it immediately when fitting the regular volume can. I swapped back to the original HV can and it feels the same (with stiction).
Your comments are welcome.

I just filled out the XV with shims to cover all the inside and dropped 10 psi. The only thing that changed was that the mid travel wallow went away but the rear feels super harsh and it stills bottoms out :-(
I will wait until I get a job and can afford to send it to push but its kind of dissapointing that such a burly bike bottoms out so easily. Definitely will not drop 600$ for a coil or maybe I should arrrrgggggg!!!

Saar how is the shim solution working out for you?
On my side, I do get better bottom out resistance than the stock HV can with the DGC mod shim, but I have yet to find a combination which Is as plush as I like (also fox 36 on the front) and yet doesn't bottom out harshly on even 2.5 feet sometimes (and I tried Many combinations so far). Its a Bummer, and a reason I sometimes miss my RFX. Maybe Push's bottom out bumper or just another shock.
I had a similar issue with the 2008 RFX until I switched to the LV sleeve on the RP23 but the opinions here on the switch are all stating it's too progressive for the Spot. Tten again, at over 200lbs maybe I should try the LV can regardless of the other opinions...

About the RC4
i'm not 200 lbs, I'm only 170 and its very dissapointing that being in the "correct" weight for this mass production shocks, they can't perform like they should. How can a burly bike bottom out on a 2 foot drop with a 170 pound guy that had shimmed the shock?
Obviously something was not correctly designed if I have to spend extra 600$ to get something that works or spend 200$ to send it to push on a new bike... little dissapointed here, I'm sorry. And the worst part is that I don't have the money to upgrade shocks so thi is a very expensive and subpar design that doesn't perform like its supposed to:madman:
Maybe it will not be a good idea?

The DCG mod affects the progressiveness of the shock, but the "dead volume" at the end of the stroke is the same, The shim I have added has some effec on the progressiveness of the travel but it's main advanage is that it reduces the "dead volume" in the shock at the end of travel and reduces the number of times this shock botoms out during agressive riding,
I still enjoy a very plush ride and still got an improved botom out control.
BBW, Beware, I had an RP23 on my 08 RFX that had a problem with bottoming no matter how much air I put in it, something wrong in the shock. I prefer coil shocks, the RC4 does fit on the medium DW 5 Spot, you just have to remove the blue anodized bottom out knob. Although, the 5 Spot with the RC4 felt about the same as my AM Flux with the CCDB so I opted for the Avy Chubie on the 5 Spot now and it's a whole different bike. I had both compression knobs all the way out on the RC4 and it still felt a little harsh. All of the coil shocks have no bottoming issue.
