FL Seatpost
The Syncros FL Seatpost uses forged 7075 aluminum alloy, and comes in the usual sizes of 27.2, 30.9, 31.6mm and lengths of 350 and 400mm. It’s not a light seatpost, coming in at 223.2 grams in the tested 30.9×400 size, but it was plenty stiff, and I never felt any flex nor sloppiness from either the post or clamping system. It comes in HP Black, HP Black with Grunge (tested), Matte White and Matte White with Grunge. The Grunge graphics did seem to get scratched in places, but the height adjustment numbering on the rear of the post has been very durable.

The FL Seatpost design is a slight departure from its predecessor and most other double bolt systems, as the post has the convex surface, and the saddle rail cradle is concave. The design uses a pair of opposing bolts, which start on the post, and go up past the saddle rail cradle and into the upper clamp, where a set of threaded barrel nuts reside. The saddle rail cradle can be swapped forward or backward, allowing a subtle amount of layback offset. The system is relatively easy to use once the rails are in place, but it can be a slight fumble finger mess getting them into a stable position. Once the saddle is somewhat stabilized, you can make micro adjustments for the desired saddle angle and lateral positioning, although it can be tough squeezing in a hex key. One issue I had was that a lot of modern frames have some pretty slack seat tube angles, and you might not be able to level the saddle without using a longer bolt? A lot of these issues are common to this type of clamping systems, so the FL Seatpost is not in the minority.

Overall the FL Seatpost was a good post, it was stiff, durable, and looks nice (loved the HP Black Grunge), but I am not a fan of the two bolt clamping system any longer, and I had issues in a frame with slack seat tube angle. Their design of the clamping system is unique and does allow some offset tuning. I have had a Syncros Ti seatpost for almost 20 years (?), so they are long lived.

    Hey Brian, had the saddle for 6 months and it’s held up great out at Mt Herman with the occasional biff, great value with the Ti rails and I like the side panels and nose protection as that’s where I always rip other saddles. Pretty darn comfy too no complaints, and I agree the nose section if good for those steep grunters like the HZ switchbacks

    Hi Brian (& Rick too)
    Firstly, thanks – i much appreciate the review and feedback. I’m considering buying this saddle, but it’s hard to find hands-on experiences like these that one can trust.
    I have a few question i hope someone can help me by answering – even if all of these can’t be answered.

    Rick, since you’ve owned it for 6 months – how’s the durability of the joint where the leather->aramid section is located? Does the leather or aramid peel off or become damaged with time?
    The reason why i’m asking is that i once has an SQLab 610 saddle, and to put it quite frankly, the nose section did not last well at all. It wasn’t aramid, but the durability was bad.

    How’s the durability of the leather color – has this been fully dyed or is it just a thin layer of black or white dye?

    Is the upper layer made of leather, or is it protected by a thin layer of rubber coating? If yes, does this seem to last or will it rub off?

    Is it suitable to use more rough bike wear without damaging the surface? (such as using denim instead of lycra pants for exampe)

    Finally – does any of you notice any kind of creaking with this saddle?

    Thanks for any inputs,
    Troels

    3.5 months of abuse (rain storms and typical damaging Colorado sunshine):
    no peeling nor even slight stitching pullout, the color has been fine, I would go with black if you are worried about it, it just has some nice age wrinkles (much like me), I think it is full leather (have to ask Syncros/Ritchey that one), since the wrinkles are a telltale sign, I wear freeride pants and its been fine, and it has been silent

  • Rick says:

    The stitching at the seams has held up great, no peeling so far. I got caught out in a good rainstorm a few weeks back and there’s a slight bit of discoloration and wear on the leather sides were the logo’s are but that’s to be expected, prior to that there was very little wear at all.

    I greased the rails prior to install and it’s been silent for me as well. This saddle is better made and has held up better than any WTB saddle I’ve owned and I only paid $65. It is on the firm side and took a few rides to break in compared to softer saddles but is comfy now.

    I would say there are more comfy saddles out there like the PureV or SDG BelAir but I couldn’t find the SDG model I wanted anywhere and the PureV or Silverado did not hold up well at all. Not to mention those saddles run at least $35 more

  • Troels says:

    Received an error when i tried to post earlier today, so i’ll try again.

    Both: Thanks for replying so quickly. Gotta say that this sounds like an impressive saddle – and silent too (what more can one ask for?). It seems as the more expensive saddles become, they get a more and more fancy designs but at the expense of durability – the FL sounds like a well-balanced choice, so this will also be my next saddle.

    Brian: Sure, i think i’ll go with the all-black version, even though the white/black looks better in my oppinion – but i have never been able to keep a white saddle anywhere near white for long.

    Rick: I was considering the WTB Silverado, but they seem to take a lot of adavantage of people who want anything beyong the stock configuration. I mean, combination of leather+Ti rails makes everything considerably more expensive. What do you think of the padding of the Syncros FL versus the WTB Silverado? Firmer, softer?

  • Rick says:

    The padding is tad bit softer on the Silverado but the saddle was not anymore comfortable for me, it didn’t holdup very well at all either. Even the side prot. panels ripped, as well as the leather cover in a few spots, will not buy another WTB.

  • Troels says:

    Me again. Does anyone know a better way of contacting Syncros except for their web contact form/application? I contacted them 2-3 weeks ago regarding whether the black dye is a surface treatment or throughout. No reply as of yet. Perhaps they got busy after Eurobike 2010…

    I spoke to their brand manager at Interbike and he thought it was a bit odd, here is their phone in San Carlos #650-517-1841
