So these days, it seems like RockShox can do no wrong. With the introduction of the Pike and the Reba, RockShox soundly laid the smackdown and said "We're back."
2007 saw the introduction of a couple new forks from RockShox, including the massive Totem and our fork, the Lyrik Solo air.
The Lyrik Solo Air is an "all mountain" fork. This means that it can take a ton of abuse, but still manage to climb the hills instead of relying on a chairlift. The Lyrik comes in three distinct flavors, and of course three price points. The bottom of the bunch is the Coil U-Turn, followed by the SoloAir and finally, the 2-Step. I will say that thikning of each fork as "better" isn't quite fair, as even the "lower end" coil U-Turn is a great fork. All forks feature a max of 160mm of travel, the updated Maxle 360, a forged hollow crown, lovely and light 35mm alloy legs, and for a twist, a post mount disc brake mount. The Lyrik also features RockShox's newest idea, a bulge in the lowers to accommodate a huge bushing.
The Lyriks also feature RockShox's new Mission Control damping system. Where the Pikes and Rebas have the wonderful Motion Control system, Mission Control is the next step up. Mission Control gives you both high and low speed compression adjustments, with extremely smooth and machined adjusters. This means you can dial in the fork completely to what you need, from standard pedaling to the big dirty hits. But of course, thats not it. If it was, it wouldn't get a fancy name like Mission Control, it would just be high and low speed compression.
Mission Control goes a bit further, and adds the platform control called the Floodgate (similar to Motion control) to the mix. Push the low speed compression adjuster down and turn right, and it pops up, engaging the forks platform. To note, this is NOT a lockout. You can tune the Floodgate to "let go" on a bump, and you can even tune how big of a bump it takes to break through the platform. When you do pop through the Floodgate, the fork returns to its standard settings, including your compression settings. Pretty neat really. Of course, you also get control over your rebound, and air pressure settings on the two higher forks.
With a full length steerer and the axle, our fork weighed exactly 2300g. Thats 5.070632 pounds, for you imperial guys. (Thanks Andrew. )
We mounted the Lyrik on a 2007 Kona Coilair, with a DHX air 5.0 in the back, and put a bit of time in on a Turner RFX too.
The Lyrik is an impressive beast. First step is to get it dialed in. The fork comes with a very handy and very accurate air pressure chart right on the back of the leg for the air models, or use different springs for the Coil U-Turn. We found the fork was a little more fun at the lower side of the scale for a suggested pressure range, making it a little more active but still ramping up nicely. Once you get the high and low speed compression settings dialed in along with the proper air pressure, you have a fork thats supple over the small stuff, doesn't wallow around in its travel, pedals very well, ramps up nicely, and is very smooth. The Lyrik was of course very stiff, as a fork with 35mm legs and a 20mm through-axle should be. There were no surprises, no leaks, no weird phantom problems. The Lyrik just rode, and was happy about it.
Climbs were a varied experience. If the climb was mellow, the Lyrik was fine. It would just motor along, and go up. However, if we encountered a steep climb, we were in trouble. The Solo Air Lyrik is essentially a 160mm fork, and thats that. There is no external travel adjust, although apparently you can open it up and reduce the travel via internal all-travel spacers. Not exactly a trailside fix though. At its full 160mm, the Lyrik was a pain to climb. The bike wanders, the front end is super high, and the Mission Control platform is actually a hinderance rather then a help. To be perfectly fair, this is NOT the Lyriks fault. ALL 5+ inch forks suck to climb, especially if they can't compress much. Our best solution with the Lyrik was to stand up, lean over the bars and try and squish the fork lower while we monster trucked our way up. The same can be said of all the 6 inch forks we've tried (Fox Float and Vanilla, Magura Wotan, Marzocchi Z1).
Downhills were great, as you'd expect. Dial in your high speed compression and let it go. the fork handles most of what you can throw at it, but of course comes short compared to a dedicated DH fork. Remember, this is a do it all fork, so if hucking 30 footers is your thing, look elsewhere.
A couple things weren't quite so peachy with the Lyrik.
Cranking up the air pressure resulting in a lot of pressure at the start of the stroke. Going 20 PSi over the recommended pressure (which is a lot) resulted in a fork that wasn't keen on moving at all, and felt very sticky. Compare this to the Magura Wotan, which gets firmer but still retains its smooth starting stroke.
If you are going to buy a Lyrik, get the damn travel adjust one. Yes, they are heavier. But, since the Lyriks impressive weight still wasn't enough to actually float the bike up the climbs, the travel adjust models will make a huge difference on the climbs. Dropping a 6 inch fork down to 4 really can be the difference between making the climb, or pulling a wheelie and having a stroke in the bushes. I always thought that was something that only Mountain Bike Action bitched about, but it is true.
Having ridden a Pike Dual Air, I can say that I prefer that system to the Solo Air of the Lyrik. Having the ability to dial in your positive and negative air chambers separately is a nice feature to have, especially since there is no travel adjust.
On a personal note, I will admit that I am a bit torn over the Mission Control stuff. On one hand, its a very useful system, and the high and low speed adjustments are brilliant, and effective.
On the other hand, I (and the riders who tried the fork) found little to no love for the platform. We engaged the platform at various times, from parking lot riding to mellow climbs, and every time, the results weren't that good. While it worked perfectly fine and exactly as it should, a partially locked out 6 inch fork just doesn't help with much. The Lyrik isn't hyperactive like the Marzocchis I have tried, so it doesn't wallow and bob all over the place like a fatty on a waterbed. The Lyrik is very controlled through its stroke, making the platform almost redundant. On the climbs, the last thing I want is a huge full extended fork, as it makes the harder climbs much more difficult. I found personally once I had my high and low speed dialed, I was good to go, and never touched the platform after that.
For an all-mountain fork, the Lyrik is a damn good time. Its supple, its smooth, its very adjustable, and it performs brilliantly. It does exactly what it promises with no surprises, and will take a ton of abuse and keep ticking. The Mission Control system is as brilliant as you'd expect from RockShox these days, giving you all the adjustments you need to dial in your fork for where ever you ride. The Solo Air is a great fork, and a worthy competitor for the Fox 36 Float, which is about as high an honor as you can give really. Just strongly consider where you ride, and whether or not you want to do without a travel adjust feature.
