    Cool-blue Rhythm Fluid 29/130

    What 's the word on this fork. I been running a Reba on my Niner SIR9 and it works well for me. But I may be putting together a El Rey with 5" rockers to replace my Turner RFX. Would prefer a 20mm fork if possible. I can use a Reba and upgrade if something better is on the way. I plan to use Hope Pro II hubs so QR or 20mm should not be an issue.

    I'm a heavy rider at 260 without gear. Not looking for a FR/DH fork. Yet want something that can handle some tougher trails.

    I am thinking of getting one also, but custom made to 120mm (looking at a 4" travel bike). I am also curious about the new Manitou with the greater offset. I'd like to know more about how offset will affect a bike and what head angles work best with more offset.

    The Fluid 29/130 is what's considered the "old" version. Very stiff chassis, mostly due to the 20mm TA. Some folks had (and are still having) great luck with the damper, while others had stiction issues that they couldn't resolve. That fork ran hot and cold for a few years.

    But it's largely been rendered obsolete by the new Fluid 29 135. Coil sprung (instead of air on the 130) and open bath damper. Super supple, super tunable, and still with a very stiff chassis for it's weight. Not remotely a FR/DH fork--this is a 4.5lb unit--including the weight of the axle. At your weight it'll be light and flickable.

    I've been riding the 135 since October, and you'd have a hard time convincing me there's a better fork out there for aggresive xc/am riding. Mine has been 100% maintenance free since I stuck it on the bike. Took ~2 rides to break it in, and it has been buttery smooth and consistent since then.



    And truthfully, if you're gonna run the 5" rockers, this is the only real choice as far as A-C and geo. Fortunately it's a great choice.



    Give it a look.

    Cheers,

    MC

    The 5" rocker is still being debated in my mind. 4" would probably do the trick also with the 29" wheel. Do you think they could modify the Fluid 29 135 for 4" travel?

    Thanks for the feedback!

    Is the Fluid 29/135 available now? If so how much are they and who has them? Thanks.

    Yes, they can if that's what you decide on.

    RS opinon

    Mike -
    you gonna share you impressions of the RS 130 fork you are testing with us? Be interested as to how it compares to the Reba you reviewed a while back and to WB 135 that you ride right now.

    Also - I thought I read that RS is making a small batch of these this week - are they all spoken for?

    The pseudo Reba rides really nice. Damper is the same as that of a Pike, which means highly adjustable and very dependable. And light. Because it's a QR fork with 130mm of travel, the chassis stiffness leaves a bit to be desired. That's to be expected. Good for non-tech xc or super light riders. Pretty flexy for me (at 180lbs). Couldn't possibly ride it full throttle on my local tech loops. Actually tried. Bled.

    Hard to compare it to the WB 135. The TA makes such a dramatic difference in chassis stiffness that they're more different than similar. Very similar in small and medium bump compliance, but the Reba gets overwhelmed quickly (compression spike) on biggish hits, where you hardly notice that same bump/drop/hit with the F135.

    I can give you a 100% guarantee that that's not true. I've heard rumors and rumblings that they're investigating a new platform, but haven't heard so much as peep about what that means. I'm not holding my breath that we'll see anything like this from RS for another year or so.

    bingo!

    "but the Reba gets overwhelmed quickly (compression spike) on biggish hits, where you hardly notice that same bump/drop/hit with the F135"


    That's exactly my biggest complaint with my Reba - and I'm having these issues on a hardtail! Local trails are rough, and this fork is stellar at lower speeds, but just gets overwhelmed at high ones.
    So......here's my question for you - would the WB 135 be insane to put on a singlespeed hardtail ? I'm considering dumping my 26in dualie, but need a better fork to make me pull this off. I know a 29 HT still has no rear travel, but my thoughts were if I could get something as nice feeling as my 03 Marzocchi Z1 on my 29er, I just might switch.

    Is 135 just WAY too much travel for a HT??? - by the way - I like my bikes slack.

    Wb 135 ?

    I have questions for you Mr. Mikesee, sir.

    What is this WB fork going to do to my RIP 9 geometry?

    [ I already know what it's going to do to my bank account... ]

    My $.02 is that anything over ~100mm on a hardtail is just weird. But that's just me. Add ~an inch to the height of your Reba (stick a book under your front wheel to simulate) and see how it looks. There's also the custom option--WB will build the Fluid in custom lengths by request. I've seen 115's, 120's, and 125's come outta there this year.

    The geo will get a bit more relaxed, but not as relaxed as you'll be with the TA chassis up front eating trails alive...

    Mods of MTBR have received a letter from Rockshox management STRONGLY advising against converting the 29" Reba to any longer than it's standard travel. It's considered dangerous. Don't do it, even if it SEEMS to work. As logical as riding with a helmet, really. Reba is an XC fork. I suppose I myself would not "XC" on a long travel fork, regardless the sticker on the lowers.

    I have a WB fluid 130 on my RIP9, and it amazing. I cant imagine the geometry being any steeper for our New England trails, the A to C seems just right.

    The WB fork looks awesome.

    I have to be honest here, $870 seems pretty steep for a fork. Do you guys foresee companies starting to make longer travel 29er forks so the pricepoint could come down to something more reasonable? What's the hold up? It seems there are enough people who want longer travel 29er forks. Maybe I'm missing something here. Is it a design thing? How come longer travel 29er forks seem to be such a confounding feat of physics and engineering?

    hey mike,

    i trust this goes without saying, but i'll ask anyway: are different spring rates available with the coil sprung WB forks? i weight ~ 80 lbs more than you; i can't imagine we'd be happy with the same springs!

    There are currently two different spring kits available. I don't know that actual recommended weight range for either. I do know that the air assist is used to fine tune that weight range.

    Best to call them to find out if the springs will suit you.

    It's definitely not cheap, considering a similar (150mm travel, 32mm stanchions, coil/air, TA) 26" fork like the Z1 costs $600. You have to consider though that these forks are being built in insanely low quantities at this point; it's almost like having a semi-custom frame built. I'm just glad to see WB building them at all, even if the price they have do it for further limits the market.

    Regardless, it is an awesome fork, and IMO easily worth the price of admission to the long travel 29"er game.

    MC, how do you think a WB Fluid 29 custom built at 115 would sit on a 4" Leviathan? Would the A/C length of a WB 115mm be about the same as a Reba at 100mm?

    If your local trails are all up hill and then all DH (like mine) speed up the rebound on the DH sections. Should help

    Pretty sure it's within a mm or two of the Reba's A-C.

    I'm riding exactly this config on The Test Sled right now. First ride reports will be posted next week.

    No problem Cloxxki, Tim @ White Bros just sent this to me. It seems that there will be a few Fluid 135s starting to trickle out but not too many due to some component leadtime issues.
    However it looks like they will be full swing this summer.

    Why not buy the Magic 100mm TA for a 100mm rear FS bike? Is the Fluid better? I thought the IMV damper was WB's best. Am I missing something?

    Personally, I don't care for the feel of a 100mm fork mated to a 100mm rear end. The fork usually gets overdriven by the capabilities of the rear end. So I use a ~140mm fork with a 125mm rear, ~115mm fork with a 100mm rear, 100mm fork with an 80mm rear, ~90mm with a softtail, 80mm with a hardtail.

    Agreed.

    I disliked my Fluid 130 air quite a bit.

    I am enjoying the F 135. It is nice when a part on a bike just disappears and you don't think about any more and just enjoy the ride. Low miles for me still though.

    IMO the F 135 is the fork for an RIP, and I think the Niner guys agree.

    The Reba I previously used was okay at low speed, but just blew through travel and flexed as I pushed it harder. Great on a hardtail though.

    It's funny how 100mm front travel and 0mm rear travel is normal on a hardtail, but the moment you get any rear travel at all, a lot of people (including most manufacturers) think that front and rear travel suddenly need to be equal.

    For instance, I'm pretty sure if I proposed a frame with a 6" fork and 3" rear, people would look at me strangely -- but this is less unbalanced than a 100mm hardtail.

    A word of caution to any tall Super-Clydesdales who are giddy at the prospect of owning a Gigabike, Behemoth or R.I.P 9 with a WB 135 in front --

    I pestered MikeSee, White Brothers, and Zinn Cycles about whether a 130 or 135 would work for a 300lb rider, and the official word from WB/MRP is "no way, Jose." In fact, the engineer who responded to my email said there's a 250lb weight limit on all the stock single-crown forks.

    Nick and Lennard at Zinn are scratching their heads over this one, because they've been putting 275-280lb guys on Gigabikes with the Fluid 130 in front. No complaints about snapped steer tubes (plenty of complaints about the seals though).

    on my 4in El Rey BUT I'm running alot of platform in the rear also for fast (for me) short XC rides. I would like the Magic on a hard tail but would not like it as a pure do all trail/XC fork on a FS bike.

    Little feedback I got from WB Friday on the 250lbs issue.

    It is not suggested for a rider over 250lbs at this time for one main reason. For more advanced riders you need more PSI in the air chamber then their max PSI range. This moves the fork up (Don't ask me how) so that pre-load or space is taken off the spring chamber. Thus a fork that rides odd and then hits the top of the spring. I asked so as long as I do not go over the Max PSI range set by WB it would be fine for a 270lbs rider. The answer was yes. Considering I'm not a FR/DH rider I think I'll be fine. I don't have issues with a Reba set at its max. They also stated there would be a HD spring available late summer. So that should even take away the 250lbs limit all together.

    Thanks for all the feedback!

    Does the air spring assist provide a preload that helps fight bob when cranking out of the saddle?

    Is the IMV available for the 135?

    New question here.

    What is the difference between IMV and Fluid systems, of course IMV functions like , simplifying, automatic lock-out and fuild will lock-out on flat and smooth asphalt?

    Any thoughts on the best fork for this bike (sson to be assambled in Norway)
    - 93kg rider - ruff XC / DT - wet and slippery conditions and freezing during winter


    - WB Fluid 130mm - 20mm TA modified to 115mm
    - WB Fluid 135mm - 20mm TA modified ???
    - WB Magic 100mm - 20mm TA
    - Reba Race.. , but then no 200mm TA so ..........

    Happy for any response

    Depends on your priorities.

    If stiffness/chassis rigidity is your biggest concern definitely go with WB.

    If you want stiff ride, and no bob (which matches the spider's rear), I would go with the Magic 100.

    If you want slacker angles, and big travel fork, go with the WB F 135.

    Don't bother with the Fluid 130 unless you want a stiff chassis, stiff ride, and longer travel.

    Reba probably has best damping, and lightest weight, but is most flexy (though not a super flexy fork by any means). Also, easiest international parts availability I would imagine. If you want an all around plush fork, at a great price, it is hard to beat.

    Spider seems to want a 100mm fork IMO.
