Fox D.O.S.S Seatpost
CTD sounds like something I was told I wouldn’t catch off a toilet seat back in Biology at school but today it stands for “Climb, Trail & Descend”, Fox’s newest anagram for its latest incarnation of products to hit bike stores for 2013..well actually right now to be exact.
Simplifying the whole suspension setup puzzle for the masses of riders who are now headed for the hills with 3 options and with some fine-tuning, its aim is to reduce any distraction on the trail…basically set the sag then hit the trail!
Along side the CTD introduction comes Fox’s only non fork/shock offering…the D.O.S.S (Drop On Steep Stuff) seat post. Being a bit late to the game…SRAM did the reverb thing 2 years ago but even they were late as well. All I can say is that I reckon Fox were waiting to ensure they hit the market perfectly first time…has it been worth the wait? Let’s find out…
Having seen quite a few dropper posts, the bar was lifted a few years back with the introduction of the Joplin, then the Reverb came along and raised it some more. Today we have a plethera of dropper posts to choose from and with the way the raise of the enduro rider is going it’s almost a must have for the “All Mountain” bike/rider.
Out of the box the usual Fox quality is evident, study box, all the bits needed..even a nice Fox sticker! The post itself is simplicity personified it’s not too flashy or basic looking but just right. Fact is I can’t really get that excited about it, it’s just a seat post after all.
Setup was a piece of piss, drop the post in the frame load up the saddle get it set at the correct height up for my super long legs, I decided to run it a little higher..since I don’t need to worry about dropping it know.
The post is cable activated…some folk were drawing sharp intakes of breath when it was first seen in the flesh, no doubt wondering why Fox hadn’t gone hydro with the post. At a guess they probably didn’t want a hose to go pop on the trail and the fact an inner cable is pennies to replace. The cable can be setup left or right just by spinning the post through 180 degrees.
Then it was the cables location…at the top of the post just under the base of the seat guts. “It’ll catch my shorts”, was what some of the internet trolls were moaning about. I haven’t caught mine yet but I guess if you had super fat thighs then the cable might rub a little but even then they’d just be rubbing the same when you walked!
Running the cable from the bars was well, like any cable. Luckily my 5.Spot has extra cable guides but even without them it wouldn’t have been a problem. I run a 1x setup and the obvious place for the remote lever was under my rear brake (on left by the way – the proper side!), it can be run top/bottom/left or right. I must say it looks proper smart, the lever sits in-board of the lever and is vitally hidden from sight from the front, even the cable exiting the lever is at the same angle as the brake hose…as we say in these parts, tidy!
The setup of the cable is easier than a v-brake…thread the cable, tighten the bolt and twist the cable adjuster to lose the slack and bingo you’ve installed the post. No bleeding of hydro hoses as well.
Riding the post is just like any other, you sit on the saddle on top of it and pedal or freewheel. Things start happening when you want to descend…hit the black lever (40 mm drop) and the post will drop into trail mode…you still have to push it down with your arse, and it’ll stop in the Trail position. 40 mm is actually quite a lot of a drop, well compared to my inseam to seat post ratio it is.
I found this was the most used mode for the local trail…there was rarely any need for me to drop to the full (125 mm) Descend mode using the silver bigger lever. However, it’ll no doubt be used on the steeper stuff we do have around..it’s just I ain’t had a chance to go butt flossing yet with it.
The silver lever can be used to drop to Trail (40 mm) mode, you just have to get used to it and you soon get the feel of the post dropping and you can therefore engage the post in the Trail mode position.
The return speed did surprise me (see the video below), the post was set at 10 psi as well which is the lowest pressure recommended…I’m not going to even try 25 psi as I’m quite happy with the return speed just now.
One thing that I was worried about was the little movement of the seat (slight twisting), it was reminiscent of my old Joplin, however this stops once the keys inside the post engage and the post is then solid, whereas the old Joplin would still rattle away.
So here’s the rub, the price…at £349 RRP in the UK it ain’t cheap, but neither were the other posts when they first came out. As with all things bike the price will drop and if you look hard enough the prices are now showing closer to the £300 mark online and in the mags.
Even with the price taken into consideration, it’s Fox “Made in the USA” quality, back up via Mojo and the all matching fork, shock and seat post which will be the attraction to most. For me it’s the smoothest, sturdiest and hopefully easiest maintained dropper post available just now.
