    Jet 9 RDO opinions on: Rockshox SID 120mm vs Fox Float 32 120mm front fork.

    I know there is a thread asking about 100mm or 120mm. I want 120mm, I know that, but what are your opinions of these front forks. Rockshox makes the SID RLT in a 120mm 15qr. Then there is the Fox 32 with 120mm and 15qr. I will use the bike in cross country and trail use. Looking for the best plush fork that is capable of trail and cross country duties and light. I can't seem to track down the actual weight on the SID but as far as performance goes, is it reliable. I owned a FOX float 32 on my TallboyC and it was the kashima coated and it was really nice, but willing to give the SID a try on my new Jet 9 RDO build if you all think its worth its salt. Comments??

    Doesn't the SID have the hydraulic lockout like the XX? The Lockout is REALLY nice and the Fox does not have that. I think the Rockshox is equally plush.

    I have the 120mm Revelation RCT3 Dual air and it is amazing! Great tune-ability. I ride in a lot of rocks, roots, and technical areas and after about 6 rides have it dialed in to where I get great small bump compliance and also big hit smoothness (for me a drop of no more than 3') After correctly setting sag I still have aprox. 10 mm of travel left after a days ride, which means to me I'm getting almost all of my travel with just the right amount left should I hit a REALLY big drop! It's also a great climber as you can adjust the lock-out 3 different ways for climbing. The fork feels stiff, tracks great, and with all the adjustability I don't think you could go wrong. I have a friend who runs a Fox 120 on his Scott Carbon and he just ordered a new RDO with the SID XX in 120mm after riding mine-he HAD always been sold on Fox.

    Hope this helps.

    Thanks for the good observations. I am familiar only with the Fox, I sold the Tallboy C for the Jet 9 RDO frame and am in the process of building it up. I had the fox 120mm float 32, the non CTD. Great fork, loved it, but I've heard Rockshox has really stepped up and I'm listening. Does your friend have his Jet 9 RDO built up yet with the SID 120mm?

    I am in the process of building up a new RDO with a 120 SID. I haven't ridden it yet, so I am not a lot of help, but my research led me to the SID over the Fox. It's lighter weight than the Fox and several have said that the SID was more reliable and required less maintenance. I have a REBA Race on my SS and it's been ok. The seals leaked a bit and I recently sent it off to PUSH for a rebuild. I guess time will tell with the SID.

    Both forks work great, The biggest thing Fox has going for it is its name. Based on the preventative maintenance schedule I would go SID. Fox is a very sensitive 30 hour service. SID is 50 hours and see a lot of people go relaxed on that without damage.

    I would look for the RCT3 damper if you go with Rock Shox.

    He has been told, because of ordering the XX1 component group, that his build won't be available for 6-8 weeks. He has, however, ridden my bike with the Revelation RCT3 fork and been able to compare it to his Fox. Liked mine enough over his Fox to order the SID. If you read these forums often (and I know you do) Rockshox has indeed seemed to have stepped up. I, for one, am totally happy with mine and would highly reconmend it for my type of terrain(see above). That said, I don't think they make the dual air Rev anymore, thus my friend ordering the SID. If you can find one though, it's probably a reduced price and I would pick one up.

    I went with the SID RCT3 solo air for a number of reasons:

    1. First is the weight savings, almost 200 grams less than the float 32 I had on my Rockstar Ti. Per my scale, with similar size steerers.

    2. Have always found Rockshox more 'tunable' meaning i personally feel that dialing a rockshox fork has been easier for me than the numerous fox forks that i have owned.

    3. I like the added rigidity of the 15 maxle lite vs. the 15qr on the fox. I can wrench it down tighter allowing for less flex in the corners.

    This is my three cents.

    Looks like the RCT3 SID come only in 9mm. Does anyone know if it comes in 15mm QR?

    As far as I can tell in a SID fork only the SID RLT and SID XX world cup come with a 15mm QR, furthermore, it seems only SID RLT is 120mm of travel and the SID XX comes only in 100mm of travel. Is this a correct observation?

    Well that changes everything. I guess I'll try and hunt down this fork. 22Rowdy22, you have the 120mm fork (I know it comes in this option and wonder if that is what you are running)? Where did you purchase yours? Am I correct in concluding the RCT3 is a step below the XX SID?

    Edit: My bad, I missed your reply 4 days ago where you made it clear you had the 15mm maxle lite. Sorry.

    Help me out here, but as I found weights on these two, correct me if I am wrong, but it seems the Fox 32 CTD 29er 120mm float is much lighter than the Rockshox RCT3 120mm Fork.
    This really surprises me, I know Fox lowered the weight on their shocks but I didn't think it was that significant.


    Here is what I found:

    Fox site says:
    32 FLOAT 120 FIT CTD w/Trail Adjust
    15QR (includes axle)
    3.22 lbs / 1.46 kg (1.5" taper steerer) [1460.57 grams]

    RockShox SID RCT3
    Solo Air 120 29" Suspension Fork
    MaxleLite15 Black MotionControl DNA 3-Position Crown Adjust
    1675grams (3.69 lbs)

    I think you grabbed the specs for the 26" version of the Fox. Here's the 29er: 32 FLOAT 29 120 FIT CTD w/Trail Adjust 15QR (includes axle) 3.99 lb / 1.81 kg (1 1/8" steerer) 3.96 lb / 1.8 kg (1.5" taper steerer)

    Yeah, I didn't think the SID came in a 120mm size, now through my shopping around I see it does come in a 120mm size. So the XX SID 120mm is basically a bit of a lighter SID version? Yeah, I'm bangin my head to make a choice here.

    Is the SID XX 120mm better than the RCT3 SID?

    Found a few nice prices, I'll keep looking for better.

    That's a pretty heavy fork for the Jet 9 RDO and also too much travel at 140mm. Perfect fork for an RIP 9 though!

    The travel can be reduced easy and its listed at about the same weight as the Fox.

    I bought this fork: Universal Cycles -- Rock Shox SID RCT3 Solo Air 29er Fork 2013

    It's the SID RCT3, 120mm travel, tapered steer tube, 15mm axle. Use the VIP15 coupon at checkout for an extra 15% off the price.

    After I cut my steerer and installed my crown race and star nut, the SID RCT3 weighed 1640g including the axle.

    Magura?

    I have been looking all around at different fork options and really liked the RS SID RCT3, this is like alphabet soup. I then discovered the new line up from magura, in particular the TS8. Similar weight to RS, nice features, and would look fantastic on my new white RDO. Any thoughts between these two. I realize rider time on the TS8 would be very limited but was just hoping for some feedback. BTW, both would be set at 120.

    Hate to resurrect an older thread but how do you guys like your SID 120's? I am making the choice TODAY on what to equip a '14 RDO with: '13 Float 32 no trail adjust vs '14 SID rct3. Any results from your builds would assist me a ton

    I have the Revelation 120 with the RCT3 and love this fork. It can also be converted to 140mm but on the Jet 9 RDO, I believe 120 is the perfect size. A friend has the SID without the RCT3 and although it is a little lighter, I like the plushness of the RCT3 over his. You will probably really like a SID w/RCT3. Now you're going to hear all about the Pike fork, which is a fantastic fork, but work with your budget, I think you'll be happy with the SID. Unless, of course, you can afford the Pike!

    I have been riding Fox forks for years but went with the SID RCT3 after a bunch of rides on demo bikes that had the CDT forks and all the great reviews of the new SID's.

    I had this same question and decided to go with a sid xx 120. I'm a long time Fox fan and I've been really happy with the sid 120. I've ridden my friends jet 9 with 100mm float and to be honest there isn't a huge difference. Don't overthink it, you'll be happy either way. One thing to note is the '13 Float has issues. I'd go with the rockshox for that reason.

    I would get the Sid XX for the XLoc thumb remote to lock it out. That thing is awesome for standing, sprinting, etc.

    I too ended up going with a SID but opted for the RCT3 damper without the bar remote. I never lock out my front suspension. So far I am completely satisfied with the SID vs my old reba rl and compared to a friends RDO with a Kashima Fox 32. Small bumps absorb fairly well and the rough stuff feels great.
