Totem solo air vs coil, i am skeptical about running a dh air fork...The boxxer wc has come close to convincing me...however i am not sold. Any drawbacks to the solo air over the coil? I have always trusted coil forks, but love the chance to shed some weight and gain internal travel adjustability. Has sram finally done the impossible? a large single crown lightweight dh air fork?

i have the 2 step totem air fork. it hasn't yet received a lot of miles---that'll change fast once mammoth and N* open---but on the 150 miles or so i've had so far, it's been pretty sweet. while riding it i don't think 'hmmm, wish this was a coil fork'.

i do like the idea of being able to bump up the air pressure for certain types of riding. i'm mostly a coil fork guy, even on my 30 lb trailbike, but the totem air is changing my opinion.

read mine and above, the floodgate is pre set so not only do you have no adjustment it is probably(from another thread i read) set too high making the fork proform worse, also im pretty sure its not internaly adjustable, so if you ride a team and race against each other and feel no difference then you dont need the adjustment and therefore puting an air cart in will just be a good way to lose weight.

I went back and forth and was leaning toward the solo air but ended up with the coil because...that's all they had in stock. I took it as a cosmic sign that the coil version was right for me - either that or I was impatient. :rolleyes:

I really love the thing so far. My only experience with Solo Air is riding a few different world cup boxxers and I have always been impressed with the feel, no idea about durability but by now they have probably nailed any issues. The only thing I can add is that the 2-Step version of the Totem has some widely reported problems - you might check it out if you were thinking about that version.

Solo air is about as dialled an air-spring setup as you're gonna get. It's easy to think they fluked it right, but the truth is they've been prototyping air springs in boxxers since ~02 or maybe even earlier... so rest assured, it works and it lasts.

i know a guy who converted his (boxxer team). solo air cartridge, honed stanchion, and a topcap was all he needed i think. got the part #'s through BTI and ordered them through his shop and bam, boxxer WC for $900, in black too

i just ordered a solo-air totem, it should be here tomorrow. stoked that i don't have to screw with the close spring rates that i fall right in the middle of on the coil version.

Do I really need a honed stanchion for the air conversion? The whole honed thing is pretty much bull****, right? Hopefully there is someone here who knows.

I actually thought it was BS too, but upon checking the parts listing, the WC actually has a different part number for the stanchions to the team/race - so they are different. The part description for the WC stanchion also says "honed". I'd imagine the inside of the honed stanchions are machined to better tolerances and have a smoother finish. The solo air setup would likely run smoother and last longer when run in the correct stanchion.

The WC uses this stanchion for both sides, which would also explain why the damper cartridge slides in easier on the WC - whereas i've heard of a few people having to be more gentle with the team/race as to not damage the cartridge's o-rings.

Cheers, for that bit of info Udi.

If someone has even more specific knowledge, sharing it would be much appreciated. :)

If you are here in the states, getting the stanchion is not the hard part. The are available through BTI..you can check yourself BTI-usa.com. The part that seems no longer available is the actual 'air spring assembly'. BTI has been out of this part for many months, and QBP (the largest distro in the us, and who deals with sram employee purchaces etc) dont now, and have never have had the parts needed.

Unless you have some kind of inside connection, or can convince sram that you need the air spring as a replacement for an existing fork, I am pretty sure this 'mod' is no longer possible.
