How has the chassis changed from MY20 SID?

SID SL has a brand-new chassis with all new lowers, upper tubes,

crown, and steerer tube. Architecturally, SID SL is narrower than

the current SID to reduce weight. The entire fork is lighter than the

current SID forks. The MY21 SID SL Ultimate is 166g lighter than

the current SID Ultimate Carbon.

What are the differences between SID and SID SL? How do I know

which one I should buy?

If you want the lightest fork over everything else, and your bike

is designed for 100mm of travel, then SID SL is the fork for your

needs. However, if you want your bike to be more capable over

rough terrain and look aesthetically more aggressive, SID is the fork

for you. The SID (35mm) provides more travel and a stiffer chassis

but is a little heavier than the SID SL. Riders that have a bike that is

designed for 100mm of travel can also use the SID if they choose.

Can you explain why there is no 27.5" options for SID? Will you

make any in the future?

We have seen a dramatic drop-off of the use of 27.5" wheels

on shorter travel bikes. We looked at market data closely and

determined that 27.5" options are not required for XC bikes.

What have you done to the chassis to ensure the fork is XC race weight?

The SID SL chassis is all new and every piece was designed to be as

light as possible and still deliver appropriate stiffness for XC riding/

racing. Weight savings primarily come from the new lower legs, CSU,

and Charger Race Day damper.

Why are you no longer using a carbon crown/steerer on SID SL?

Carbon parts take a lot of time to develop and we focused on the alloy

crowns first. In looking at what we accomplished with aluminum, it will

take more research to understand if we can achieve any performance

or weight improvements with a carbon CSU. On SID SL Ultimate

models, we are machining the crowns and anodizing them for better

aesthetics and a small weight reduction.

Are the lower leg seals different to MY20 SID SL forks?

Yes, we have upgraded to SKF wiper seals on all SID forks.

Is the (Charger Race Day Damper – 32mm) damper backwards

compatible to current 32mm forks such as SID?

Yes, the Charger Race Day damper is backwards compatible with all

100-120mm SID and Reba forks back to MY14.

How has the chassis changed from MY20 SID?

Every piece of the MY21 SID chassis is new. Most notably we used

35mm upper tubes to provide more stiffness and a more aggressive

aesthetics on XC bikes. Every gram is accounted for and all of the

pieces together provide the best combination of weight and stiffness

for 120mm bikes all with a striking new look.

Can you explain why there is no 27.5" options for SID. Will you make

any in the future?

We have seen a dramatic drop-off of the use of 27.5" wheels on

shorter travel bikes. We look at market data closely and determined

that 27.5" options are not required for XC bikes.

Can you explain how you came to the decision to only use a

44mm offset?

Many of our product development decisions are driven by data. It’s

clear that most of the industry is moving to shorter offsets for all

bikes. We made the decision to keep the offering simple and only offer

one offset that will work on most, if not all, XC bikes. If your bike is

designed around a 51mm OS, the 44mm OS will only slightly change

the handling characteristics of your bike by increasing the mechanical

trail and making the bike more stable at high speeds and on descents.

Why are you no longer using a carbon crown/steerer on SID?

Carbon parts take a lot of time to develop and we focused on the alloy

crowns first. In looking what we accomplished with aluminum, it will take

a lot more research to understand if we can achieve any performance or

weight improvements with a carbon CSU. On SID Ultimate models, we

are machining the crowns and anodizing them for better aesthetics and a

small weight reduction.

How have you increased the performance and reduced friction in the fork?

We have continually worked on developing better alignment between

the CSU and the lower legs. We are laser focused on bushing sizing.

Additionally, we moved to a lower friction SKF wiper seal. The Charger

Race Day damper also inherently has less friction than the rest of our

cartridge dampers.

What are the user benefits of Maxima Plush Fluids?

Maxima Plush damping fluid is the most advanced fluid we could find.

Primarily, the fluid reduces friction and extends seal life. We have

confirmed this with extensive in-house testing. Additionally, there are

elements in the fluid that ensure that damping is consistent over a much

wider operating temperature range than standard damping fluids. Finally,

the fluid helps reduce damper noise during a dampers use on top of the

terrain hit after hit.

What are the changes to the new DebonAir air spring?

There are several developments on the new DebonAir spring. First,

we moved the dimple lower in the upper tube to swap at top out

making the fork ride higher in its travel. We also changed the shape

and size to be closer to Pike and Lyrik. We also changed the same

top out bumper that we use in Pike and Lyrik as well. We have

added a custom shaped cup that captures the top out bumper that

allows us to tune the way it feels. Finally, we made the seal head

smaller and lighter. All of these things together create the feel of the

air spring that we wanted for XC riding.

How exactly is the new DebonAir air spring tuned to suit XC riders?

Negative to positive ratio compared to trail and enduro ratios?

The tune we chose is similar to what we have in Pike and Lyrik.

The difference is in the designed-in ride height. Depending on set

up, Pike and Lyrik have a ride height of 25-35% sag. SID is in the

neighborhood of 15-25%. This is an intentional difference based on

the intended use and the amount of travel. Because there is less

travel, we want more of it available for use than a longer travel fork.

Is the new DebonAir air spring backwards compatible to previous

generation SID forks?

No. As SID is a new 35mm chassis, the air spring will not fit

previous 32mm generation SID forks.

How much does the Charger Race Day damper weigh? And what is

the weight compared to MY20 SID damper?

MY21 Charger Race Day Damper - 35mm 96g

MY21 Charger Race Day Damper - 32mm 88g

MY20 SID Charger 2 RLC Damper 186g

Is the (Charger Race Day damper – 35mm) damper backwards

compatible to current 35mm forks such as Pike or Lyrik at 120mm?

No, the 35mm Charger Race Day damper is not backwards

compatible with any of our current 35mm forks. An upgrade kit

will be available for riders who have a SID Select or Select+ who

want to upgrade to the Charger Race Day damper.

How have you reduced the overall weight of the Charger Race Day

damper so significantly?

Primarily, the weight savings is a result from every part being

smaller and using less fluid. Additionally, we looked at every piece

and asked how it could be lighter. The heavily machined top cap

is an excellent example of this.

What compression and rebound adjustments are on the Charger

Race Day damper?

All of the forks feature a two-position compression – open and

lock, and low-speed rebound compression. Forks are also

available with TwistLoc remote option.

Are there differences in the tune on 32 and 35mm SID?

Both are geared for XC bikes so we wanted the damper

characteristics to be the same. With shorter travel platforms such

as SID, there is less need for multiple damping adjustments,

especially on the High Speed compression and rebound side.

Which bikes will I find with SIDLuxe Ultimate shock specification?

There will be extensive specification of both SIDLuxe Ultimate and

Select+ on OEM equipped bikes. Many of these will be launching in

the coming months.

Can I buy SIDLuxe for my current XC bike – what is the planned AM

availability?

We will have several OEM model specific versions as well as a robust

offering of generic tunes and sizes that can be re-tuned to fit our

customer’s needs.

What are the color options available for SIDLuxe?

SIDLuxe Select+ is available in Black. SIDLuxe Ultimate is available

in Black and SID Blue.

How have you made the shock lighter than the competition?

To deliver the lightest RockShox shock offering, we made SIDLuxe

shocks as small as possible while maintaining the performance

our riders and racers would expect – smaller means less materials,

therefore less weight. Smaller means less air volume too which is

suited to XC requirements.

The shock is so small - how does this affect the air spring

characteristics?

Due to the size of the shock, the air volume is smaller. Meaning we can

make shocks with a supple ‘off the top’ initial stroke, and a progressive

air spring through the stroke, with plenty of bottom out control for the

bigger hits. Perfectly suited for XC needs.

Is the positive air spring adjustable?

The positive air spring can be adjusted with tokens similarly to our

other shock offerings. 0, 1 or 2 blue tokens can be installed easily into

the air can to tune the air spring to a rider’s needs.

How would you describe the damper tune on the shock?

The damper is tuned to cater for a wide range of leverage curves on

XC race bikes. Great ‘off the top’ with lots of control on bigger hits.

We built the shock knowing that we would have a more progressive

air spring due to a smaller volume. In turn this means we could use a

lighter tune to deliver the same characteristics that our riders would

expect. Supple, supportive and a super firm lockout when needed.

The lockout feature requires very little force to switch between open

and a super stiff lock.

ROCKSHOX SIDLUXE / FAQ

Do I need to use a tool to adjust rebound settings on the shock?

In order to deliver the lightest possible shocks, we saved weight in

every area we could. Removing the rebound adjustment knobs

and replacing with tooled options saved notable weight on each

shock. SID Ultimate and SID SL Ultimate forks have a removable

rebound adjustment knob which is used to adjust the settings on

SIDLuxe shocks.

As the shock is smaller and lighter, can we expect it to heat up quicker?

During testing we found that the new SIDLuxe shocks were able to

maintain normal damping and air spring characteristics in racing

conditions.

Why haven’t you made a three-position shock?

We’re always listening and developing shocks to suit our customers’

needs. The current and most pressing ask has been for a lighter shock

suited to XC needs with an extra firm lockout and an open setting for

maximum control and traction.

What sizing and mounting configurations is it available in?

Available in standard and trunnion mount. Shocks are available up to

50mm of stroke across the sizes required by our OEM partners.

Are SID shocks tunable by service centers?

Absolutely. While we will be offering many OEM specification shocks,

we will also work to offer shocks for many current bikes currently

running alternative shocks. These shocks will have the required sizes

and mounting types and some will require tuning by a service center

to meet a rider’s needs.
