You're getting pretty serious about this air business ain't ya .TimZ said:I have only run coil suspension. Are there any special issues for running air suspension in the winter?
Cold = indoor bmx, try it you'll like it.Ricko said:You're getting pretty serious about this air business ain't ya .
I never liked the way that Cane Creek that I had on the Isis originially felt in the colder weather, that's part of the reason I went with the Romic. It seemed that I had less small bump compliance and dampening wasn't as good in the colder temps.
Of course that CC was old technology so let's see what some folks have to say about some of the newer air shocks that are out there now.
You riding this weekend? Let me know when and where...seems everyone and even Derek is hiding from the cold this year!
If the air inside the fork/shock heats up when in use, it does so whether it's 0 degrees or 100 degrees. So you still need to compensate for the change in temperature.rpet said:Won't the air in the shock heat up quickly once you start riding due to suspension action/pressure?
How does one account for that if airing-up the shock when it is very cold, as a few of you have suggested?
In this case, the heating comes mainly from friction in the seals rather than pressure. This does happen in your shocks too, but they don't get very hot (or even warm) on mountain bikes. Certainly not enough to cause any problems.rpet said:I'm no engineer, but my tire pump noticeably heats up from pressure when pumping a tire up to 35psi... Consequently, I bet my 2" stroke Fox fork is too when my roughly 200lbs (rider, gear and bike) are pushing on it hundreds (?) of times per minute while trail riding.
Maybe it's not going to be 100 degrees in the shock canister, but it's going to be significantly warmer than the outside air, I'm guessing.
This doesn't change the fact that if more air is lost due to cold temps before the ride (you keep your bike in a cold garage or during the trip to the trailhead on a bike rack), you need to put more air in. But I'm just questioning at what temp it makes sense to dial in the air pressure exactly; I figure maybe 20 minutes into the ride would be a good time.
I was having the same problem with my AM 1. I sent to Marzocchi because it was still under warranty. Marzocchi tech called me today and said it was losing air because an excessive amount of dirt got past the dust seals and was not letting the air/oil seals, seal properly when cold. However, while it was there, tech checked whole fork over carefully and found that the steering tube was damaged and both upper and lower stanchions were bent. Sooooo after some discussion, they warranted uppers, lowers, bushings and seals. I had to pay for the steering tube $50 and they are using the existing dampening rods and stuff so it's mostly a new shock. Bonus is that the lowers are being replaced with black ones so I can get rid of that ugly tan color. I'm glad they covered most of the items, says alot for their customer service. I just hope it's FIXED! If you are under warranty, opening the fork will void the warranty so I would send fork in. Otherwise I would replace the seals with Enduro seals from enduroforkseals.com as they are cheaper and better than factory seals.tia4 said:i have the same fork Z1 FRSL and experiencing the same symptons in cold weather...i can hear the air leaking from the seals not the valve. Is there a fix with out having to send it back?
