On Test now – the SYNCROS FL 29er Carbon rigid fork: by “c_g”

If you have read my coverage of Eurobike´10, you will remember how I stumbled across the new SYNCROS FL 29er rigid fork (here). While all the others had been rumored about or at least been announced, this one came to me as a complete surprise (maybe I simply missed its announcement, but the surprise was a pleasant one).
Seeing this gem sitting there at the SYNCROS booth surrounded by their new 29er hoops instantly made me want to ride this baby.
A few things are striking upon first glance: 
* The Monocoque crown/steerer assembly
* 100 % Carbon construction (incl. full carbon dropouts and disc brake tab)
– no metal to be seen anywhere
* Beefy 34mm blades
(round cross section throughout) for excellent lateral and torsional stiffness
* Beautifully understated matte black finish with white (plus some red) decals
Here are the other specifications and details of the fork:
* Ultralight 585 grams (with uncut 300 mm steerer tube – real weight)
* Room for > 2.5” tires (measured clearance of ~ 90 mm or 3.55””)
* Msrp: Europe 499 EUR (VAT Included) – US and International 529 USD
* NO Rider weight limit
* Disc only (IS mounts)
* max rotor size: 203mm
* Limited 5 Year Warranty
* 480 mm axle to crown length
* 38 mm offset
* Available by January 2011 at your local bike shop
What?? – Have the SYNCROS designers been missing the fact that rigid 29er forks are getting shorter and receiving more offset?
What might seem a bit odd at first, could actually be a really smart move by SYNCROS. Think about it: For over ten years all 29er frames (be it by a major manufacturer or by your custom frame builder) were designed around 38 mm offset forks and only in the very last few years has the trend in geometry been altered. That is a lot of frames, many of them still being ridden (and loved), often with their original fork, that is sure to have a 38 mm offset.
Enter the new 29er SYNCROS fork and many riders might have the perfect aftermarket upgrade that will not alter their beloved bike´s handling at all (as most other “new generation” rigid forks would).
Here is what SYNCROS U.S. marketing director S. Coffey had to say on this:
“We have dabbled with various offsets, lengths and frames with mixed results. In our ride testing we found that a 480mm/38mm offset obviously works fine on ubiquitous “old school” geometry, and despite the math, still works really well on “new school” bikes.
Note: our lead test rider was Thomas Frischknecht, riding a Scott Scale 29, which is about as new as it gets. In contrast, a newer >45mm offset fork works, but does not work quite so well, on a pre-2008 frame.”
Unlike others, Syncros does not make frames, and unlike Fox, Rock Shox and Manitou our fork business is not heavily anchored to OEM business, so we need to offer a light, strong and sweet-riding rigid for that will work with the largest number of existing bikes out there as an upgrade. At this time a 480mm/38mm offset is the best choice.”
Besides, who of us can claim to KNOW with certainty how such a geometry fork on a “modern” frame will really affect the bike´s handling? Sure the fork will put my front end slightly higher, compared to the 470 mm standard of all other 29er forks on test, after all it suspension corrected for 80-100 mm. But how will the difference in offset show? Will it show at all? And if, how dramatically?
I hope to be able be able to shed some light on these questions by really putting the SYNCROS FL 29er fork though its paces and by testing the alongside other rigid 29er forks and on different bikes to really find out by first hand experience.
Stay tuned for my first impressions soon.
RIDE ON,

Ps: SYNCROS and their European distributor have been amazingly helpful in getting this fork to me as quickly as possible for what might well be the first ever public review on this fork. (Thanks for that!!).








This is a really great looking fork. I saw it at Interbike and was very impressed. I was told it has a short internal alloy sleeve in the steer tube/crown. But I think that is more a beefing it up for a failsafe. Still crazy light and the design blends in to any frame nicely.
Agreed, nice looking fork. Is carbon so hard to manipulate that fork manufactures can not offer multiple lengths and offsets. How cool would it be for WB, Niner, SYNCROS, to offer forks that would work well with a TD-1 and well as any other 29′r ever made. While 38mm and 485mm might work ok, it must really piss off designers of “new” 29′s frame geometry that more choices are not available. Anybody offer a carbon fork with custom length and offsets? Calfee anyone?????
any idea what this thing will cost?
Upsidedownbiker: It is common with multi-piece forks to have a spigot (or joint sleeve) connectiong the legs to the crown. Whether it is made of alloy as you say, of crabon like the DT-Swiss XRR or of steel like the PACE of old – I have no info yet but will post it once I find out.
Yogi: So far all exisitng rigid forks come in one offset only. Some areavailable in two lenghts to accomodate 26″ or 29″ but that is all the range you currently have. But my info is still correct, then RAGLEY (or X-LITE, which is the exact sma fork with dfferent graphics) will be putting out a rigid carbon fork in various lengths and offsets. So there is hope
.
Dave: retail for the SYNCROS FL 29er Carbon is siad to be USD 529.- or € 499.-.
(This and other infos on the fokr can be found in the EUROBIKE article, linked above in this post.)
This fork has very vertical axle slots. How does Twentynine inches weigh in on the issue of whether a disc brake can pop an axle out of such slots—including the related issue of disc-brake-related skewer loosening?
(I’d say *alleged* issue of disc-brake-related skewer loosening, but I’ve actually experienced that part.)
WOBG-Only happened to me once! I am a old school v-brake guy. I put my front wheel in, I guess I forgot to really tighten my QR(it was closed however). First few times I used the brakes, I felt a flopping feeling…..finally stopped to check(I thought it was going to be a loose headset).
I can not imagine what would have happened if I did not have forward facing dropouts!
Maybe I would have been like that TV commercial where the MTB rider loses his front wheel entirely and has to manual to catchup to it…….
Unless 485mm/38mm is exactly what a buyer needs, the $500+ price is not competitive. E.g., you can purchase a Niner for $350 or a Ragley for around that price.
Got no idea why their product is so expensive.
485mm/38mm – seriously? I suspect they will only sell to the uninformed…
Fork is actually 480mm/38mm -not 485.
Does the carbon steer tube scare anyone?
@Rhino – Not me. If anything, the steerer is the best piece to make from carbon. It’s the only part of the fok protected from chips and impact damage in a crash. Sure, you have to be careful with how much you tighten the stemp and all, but a torque wrench is an easy solution for that.
@WOBG: I have a former tester, (Captain Bob), who can pull the front wheel out of any fork with the typical vertical slightly canted drops that were typical on forks before disc brakes. If the bike has a disc brake, he can get the wheel to pop out no matter what QR is used. Forward facing drop outs eliminate this, obviously, so as far as being an advocate of the forward facing drop out on a disc brake equipped fork, you can count me in.
That said, through axles eliminate the problem as well, and stiffen the fork laterally and torsionally. For everything but XC racing, I would advocate for through axles.
@Rhino: Both Grannygear and I tested the Epic Marathon 29, which is equipped with a carbon steer tubed Reba, and we had no compunctions in doing so. It is a robust and trustworthy way to use carbon, in my opinion.
HI
IM buying a TI Salsa Fargo and do you think that fork would work great on that bike? Thanks a lot
@Larry: Well, this could be a long answer, but I’ll just say “it depends”.
Would it “work”? Yes. Would you “like” it? Sorry, I can’t answer that. I would point out that the design intentions for a titanium Salsa Fargo weren’t developed around the type of geometry this fork has,so that might be something to think about.
