Rockshox SID Final Overview – BIKEPACKING.com

The “XC racing” class of elements has all the time conjured photographs in my thoughts of taco-ed 24-spoke wheels, shralped paper-thin 2.0” tires, and ill-equipped jittery components ready to be snapped in half on something aside from buttery easy singletrack. Clearly that’s an overblown preconception. Simply watch any trendy cross-country race. The technical options and hits that these racers and their bikes rail by at full bore eclipse what 90% of us leisure riders will ever face on our every day rides.

Nonetheless, my first expertise with a SID (Superlight Built-in Design) fork in 2021 had me anxious as I used to be making ready to drop a quick, technical descent for the primary time on the Why Cycles El Jefe hardtail I used to be testing on the time. I half-expected it to really feel like a wobbly pair of sea legs when pumping by the rocks and roots on the best way down. To my shock, it charged by the path comparatively poised and assured, and it felt and carried out much better than I anticipated. At that time, Rockshox had simply bulwarked the SID with 35mm stanchions (up from 32mm) and made a number of different tweaks to the 2020 iteration. Nevertheless, it wasn’t with out flaws, as evidenced in experiences on-line and from native mechanics.

Now, simply two years later, the model introduced one other spherical of upgrades to the vary of SID suspension merchandise. I had the possibility to check the newest RockShox SID Final 3P with the brand new Twistloc Final distant lockout for a number of months previous to its launch. Right here’s my evaluation after 300+ miles of bikepacking and path driving.

RockShox SID Final: Stronger, Lighter, Cheaper?

I don’t actually take a look at XC-rated elements the identical approach anymore. Not because of my expertise with the 2020 SID, however as a result of I’ve been impressed by a number of different ultralight/race-oriented merchandise through the years. Most of them squarely align with the primary two qualifiers of the previous adage, “Gentle, robust, low cost… decide two,” and eschew the third—not superb for wallets, however tremendous for folk who place a precedence on decreasing weight and are prepared to make the funding. The RockShox SID Final isn’t any exception. It sits on the highest shelf of the SID vary and locations a little bit extra emphasis on “robust” because the “jacked-up, longer-travel sibling” to the SID SL, the model’s ultralight 32mm stanchion-equipped fork. RockShox even teases the nebulous downcountry time period of their advertising and marketing supplies for this fork to trace at extra rugged backcountry utilization past racing. Nonetheless, the brand new SID Final is lighter than its predecessor, regardless of the model’s declare that it’s additionally stronger.

RockShox’s transfer to 35mm stanchions in 2020 distanced the SID even farther from the unique mannequin, which debuted in 1998 with frail 28mm stanchions, a whopping 60 millimeters of journey, titanium V-brake bosses, and a needle-valve to regulate air stress. Nonetheless, the larger stanchions didn’t come with out sturdiness considerations. I’ve heard a number of experiences from mates and mechanics about frequent points. Most notably, stanchion bushing play indicated by a knocking sound that in the end forces the higher meeting to be warrantied. The brand new SID goals to repair this downside with longer higher tubes for elevated bushing overlap. In line with RockShox, “This implies each the higher and decrease bushings are absolutely engaged to scale back facet hundreds throughout impacts, leading to much less friction, and elevated long-haul sturdiness.” They really made the identical replace to each the Pike and Lyrik for comparable causes, and this improve alone may clarify the fast turnaround of this vary revamp and launch.

The opposite change within the SID chassis comes within the type of a slight tweak to the crown. RockShox launched the properly machined crown within the 2020 fork, however the newest mannequin seems to have actually shaved extra metallic off of the column-shaped bits on the prime of every higher leg, giving them a slight hourglass form. Nonetheless, that doesn’t actually clarify why the brand new SID Final dropped about 50 grams, particularly contemplating it was up to date with an extended higher meeting.

Charger Race Day 2 (3P) Damper

A few of that weight financial savings may very well be credited to the brand new Charger Race Day 2 Damper. It seems to be comparatively much like the previous model, however SRAM claims it was up to date to be even lighter. The Race Day 2 is available in two flavors: two-position (2P) and three-position (3P). The 2P has Open and Lock settings, and the 3P damper I examined has Open, Pedal, and Lock. On each, Lock is a real strong lock-out, and the Pedal setting partially companies it up for extra pedaling leverage. The one different technique of adjustment is a 20-click rebound dial on the suitable leg that’s turned with an extruding built-in L-shaped Allen key.

Like its predecessor, the brand new Race Day 2 damper is a bladder damper, which is a sealed system with a rubber bladder that expands and contracts as oil strikes by it. That brings up one other difficulty I’ve heard about: the bladder failing, which is normally a results of lack of upkeep and never bleeding it recurrently. That being stated, we had been lucky sufficient to place fairly a number of exhausting miles on three totally different SID Final forks over the previous few years. We put over 400 miles on one (earlier 2020 mannequin), 200 on one other, and about 300 on this one. None of them had any points with the damper or the bushings.

Observe that the Charger Race Day isn’t the one fashionable bladder damper in the marketplace. Fox’s FIT4 is one other frequent one. One draw back to the Race Day and new Race Day 2 dampers is that RockShox doesn’t embody a alternative bladder with their rebuild kits, so you need to purchase a complete damper if it fails, or undergo a educated suspension skilled who can set up a third-party bladder when getting it serviced. With a fork like this one, having common upkeep is a should, and having it checked and overhauled earlier than a giant journey can stop points from arising. Native suspension technician and proprietor of Collette Machine and Instrument Randy Collette remarked, “They’re [lightweight] race merchandise and are designed to be serviced extra ceaselessly. Much less oil equals much less weight equals extra frequent service.” He added that the hot button is having it correctly arrange, “I really feel like a correctly assembled and bled one with a fitted sealhead might final indefinitely.”

For what it’s value, RockShox damper service intervals are normally beneficial after roughly 200 hours of use. That’s a tall ask, and my unsanctioned technique is normally to only have a fork serviced previous to occurring a giant journey. If one thing occurs at house, it’s not that onerous to have it repaired domestically.

New DebonAir+ Air Spring

The brand new SID Final additionally acquired a redesigned air spring known as the DebonAir+, the identical identify used for the springs within the Pike, Lyrik, and Zeb forks. Nevertheless, this DebonAir+ is a little bit totally different. Essentially the most seen change is the brand new top-out spring, which has a coil spring slightly than a rubber bumper. SRAM claims this prevents hysteresis, the lag when the journey modifications instructions attributable to the build-up delay of damping drive. This coil-spring design was conceived to take care of consolation and traction within the preliminary journey, a high quality extra related to XC trails, dust roads, and fewer aggressive driving.

The larger change is that they added 50% extra destructive and 16% extra optimistic quantity to the air spring, making the fork extra supple and permitting extra adjustment primarily based on stress. I set mine as much as 20% sag and just about left it there. It’s spectacular how good this fork feels on small bumps, which I’ll dig into later.

Costs, Weights, and Options

The brand new RockShox SID Final is much less expensive than a lot of the different top-end forks accessible in its class, and oddly, it’s cheaper than the primary 26” SID launched in 1998, form of—that one bought for about $700, which equates to roughly $1,300 in right now’s {dollars}, in response to an inflation calculator. Much less is much less. The present mannequin lacks the high-speed and low-speed compression changes you will discover on the Pike (Charger 3) and Fox 34 (Grip2), but it surely’s far lighter in consequence.

As an instance weights, costs, and options, I put collectively this chart to point out a variety of 120mm forks which are accessible and tacked in a few forks that may be arrange with a 120mm air spring after buy. It’s a flexible and fashionable journey size, towing the road between path driving, endurance biking, and bikepacking. As you’ll be able to see, the SID Final can also be the lightest possibility in the marketplace.

On the Path

On my preliminary journey with the SID, the very first thing I observed was the load financial savings. It changed a ~2019 Fox 34 Manufacturing facility fork on my Nordest Sardinha. That fork weighs 2,045 grams (4.5 kilos), so I successfully eliminated 1.2 kilos from the entrance finish of the bike, which isn’t insignificant. It’s like upgrading to carbon wheels, a carbon handlebar, a lighter tire, and extra, multi function go. It turned a unique bike, requiring me to place extra weight over the entrance finish, which is an efficient behavior to get into anyway. It additionally negated practically half of the load of my handlebar bag weight when bikepacking.

I arrange the SID primarily based on roughly 20% sag, which registered 75PSI on the gauge with my 28-pound bike and 165-pound physique. The rebound was dialed on the midway level with 10 clicks, and I just about left it there, turning it down a few clicks slower at one level. For the document, I’m not somebody who obsesses with perfecting suspension settings on forks which have numerous adjustability. I normally set the dials within the center place and go, often making some small tweaks to enhance traction or really feel on the path.

With forks just like the Fox 34 or RockShox Pike, it’s actually exhausting to discern the consequences of 1 click on of low-speed compression or high-speed compression adjustment. The SID doesn’t have that possibility, which is form of refreshing. Rebound pace and air stress are the one two variables, so that you’re left with how this fork was engineered. I later checked the urged settings on RockShox Trailhead, an app to reference suspension setup. It beneficial 79PSI and 6 clicks from sluggish.

Talking of changes, one factor that will get below my pores and skin about some forks is how they will magically really feel off from one journey to the following. It’s nearly as in the event that they immediately go approach out of tune resulting from barometric stress or my failing thoughts taking part in methods on me. I typically discover myself re-checking sag, adjusting air, and eager to fiddle with compression settings. This hasn’t occurred to me with the SID, which has usually felt fairly constant. Which may be partially resulting from its simplicity and the dearth of placebo at work; there’s no intimidating compression dials to regulate—or lead you to assume that they by some means went awry—so the one factor that may be modified is air stress.

The SID’s efficiency on small bumps impressed me out of the gate. It’s higher than my Pike Final in that regard and feels extra just like the Fox 34. It does a terrific job at buffering small and medium-sized rocks and roots if you’re simply pedaling alongside, climbing, or traversing throughout a bumpy path. It additionally feels fairly nice on dust roads and gravel for a similar causes.

Twistloc Final

I additionally tried the brand new Twistloc Final this go spherical, which RockShox claims provides riders higher dropper put up compatibility and a cleaner cockpit primarily based on some structural tweaks.

That is solely the second time I’ve used a distant lockout and the primary time I’ve used a twist controller for something in an extended whereas. I used to be anticipating to be unintentionally partaking it on a regular basis, however that wasn’t the case. They did job with the proportions and rigidity between the shifts. It requires quantity of drive and has a satisfying click on when engaged into the Open, Pedal, or Lock settings. There’s additionally a vivid blue tick that makes it simple to see the place.

As anticipated, I didn’t use it as a lot as I might or ought to have; the SID Final pedals fairly effectively with out locking it out. That being stated, after I did flip it into Pedal mode for a climb, the effectivity was noticeably improved. At first it felt a little bit too springy; that’s after I backed the rebound down a little bit slower. I got here to understand with the ability to change into the Pedal mode on longer loaded climbs throughout our five-day bikepacking outing in Colorado. I not often used the complete Lock, however that might be nice for a singlespeed, which is the place this fork goes subsequent.

The textured grips are snug sufficient, however you may also get them in a easy texture. That brings up my one con with utilizing this distant lockout interface: it limits ergonomic grip choices. I can now not use Ergon GA3s, not less than on the left hand.

SID vs. Pike

That brings me to the opposite RockShox fork that I’ve spent numerous time with, the Pike. I’ve the newest Pike Final, and I’ve moved it from bike to bike and altered it from 120 to 130 to 140mm of journey. The obvious distinction between it and the SID is the load. Though each have 35mm stanchions, the Pike is a beefier fork general, with a thicker decrease arch and beefier tubes to present it a stiffer chassis.

One other contributor to the added weight on the Pike is the damper. The Charger 3 is extra subtle than the Race Day damper with much more tunability constructed into it. It has a self-bleeding inside floating piston design, which requires much less upkeep and is arguably extra dependable than a bladder damper because it doesn’t depend on an increasing rubber bladder to handle oil motion. Nevertheless, in contrast to the SID’s Race Day 2 damper, the Charger 3 doesn’t have a Lock or a Pedal mode, a function that’s invaluable to of us who’re racing or anybody wishing to maximise climbing effectivity.

The Pike is best suited to prolonged driving on rugged and technical terrain than the SID. The Pike’s Charger 3 damper designed to be overworked and has higher inside technique of regulating fluid and air inbuilt to perform this. In brief, it’s extra tuned to handle larger hits as they occur in quicker succession. That interprets to much less higher physique fatigue and higher efficiency on lengthy tough descents. Nevertheless, I discovered the SID Final and the brand new Race Day 2 damper to be faster and comfy on terrain the place the fork is engaged on the prime and center of its journey. And with the Pedal mode and diminished weight, its quickness and effectivity make it superior on the climbs.

The Pike has a number of different options that the SID lacks. One is the stress reduction valves, buttons on the legs that purge air stress construct up within the fork attributable to variations in altitude or temperature. I’ve used these fairly a bit on the Pike, and so they work, significantly when touring. The Pike additionally has the brand new ButterCups tech. These elastomer pucks reside on the finish of the damper and air spring shafts and buffer high-frequency vibrations, akin to tire buzz (much like those used to eradicate chainsaw motor vibrations). I actually thought this could be a little bit of a gimmick at first, however I used to be capable of discern the distinction when driving it again to again with an older Pikes.
