Shock/Tyre Pump
NB: Originally posted elsewhere on the Global Riders Network and appears via syndication.
Good morning fellas. Just a quick question! Im wondering if such a thing exists where i can have a 2 in one mini pump to put in my camelback. Ive got a track pump which has the dual head (Presta/Shrader) but looking for something similar with a pressure gauge that fits nicely in my camelback. Basically i don't want to carry a separate pump for my shocks and my tires not to mention my small pump dosn't have a pressure gauge which is pretty useless.
Cheers!!
Jono.

you can buy shrader/presta adaptors so you only have to use on pump. however may I ask why you would ride on the trails with a shock pump, unless you are specifically going out to tune your suspension/ playing with pressures.
I cant think of any other reason to take it out.

Riding with a shock pimp is a great idea, the first few times after getting new shocks/forks. No point waiting till u get home to adjust. Why not make changes halfway through a 20km ride.
I have seen a giant branded dual use (shock and tyre) pump in the bike shop in wangara. I'm sure it was $40 to $50. The bike shop on prindiville road. Not the one in he markets.
I used to carry a shock pump in my Camelbak so I could play out on the trail. I don't bother now, but after the Oaks Trail ride a couple of weeks ago I probably need to spend a little more time working on suspension setup.
When I rode the oaks fire trail I found my suspension too hard , when I got into the single track I adjusted my rebound too take out the harshness and it ended up being a better ride to the end
I thought at least a part of it was me not being able to see much trail detail due to too-dark and smeary glasses, but the high-speed shallow chop on the fast straight fire road parts was pretty harsh.
Unusual for a Lefty, but these new bootless forks are entirely differnt beasts.
I already run the rebound on the front at minimum but have reduced the pressure 10psi to get me from 25 to 30% sag. Put half the volume reducers back in ready to go for the next test ride.
I just have to kick this stupid cold so I can go ride!
I find myself always fine tuning my suspension settings just to refine the ride that little bit more each time, and yes each ride the bike is defiantly getting more compliant smoother and grippier. Especially with my service recently the bike is running better then ever before. Also depending where im riding i find i need to pump up accordingly. I.e. at omv i found my bike very squirmy on that first undulating timber section, pumped up the rear a bit and hell yeah that worked.
I always carry both with me and although ive got quite a large camelback i'm sick of carrying so much weight in it (and bulk). Nice to no there are some options for me and my predicament.
Only thing i would love is the rlc cartridge in my forks as i only have a float rl with only low speed compression and rebound, ive found especially in longer travel bikes you can set up the low speed settings quite well but then in the faster fire trail and flowing stuff the bike just wallows around so its sort of a balancing act. Oh well... Maybe my forks just need a "PUSH".
Cheers.
That looks like a pretty neat unit, especially suited to traveling abroad with your bike or going on multi-day rides.
Has anyone tried it who could give us some feedback on it?
I have one on order from my LBS, should be here this week. Once I've used it a few times I'll let you know how it goes.
Thanks. That'll be interesting.
I got one when I purchased a new Anthem Dec 2013.
I carry mine every time i ride because i need a pump in case I puncture, I have never adjusted my shock pressure mid ride, i usually check\change it before i leave and then only play with the CTD and rebound when I'm riding.
I don't mind it's weight or size as I ride with a Camelbak. it has been in there 7 months and still looks good and performs when needed. Apart from wiping some dried gel off it once, it gets used, put in the Camelbak and forgotten about.
When I use to adjust my shock pressure it works well and doesn't take long to get it to the desired pressure.
When I have had to use it in the field to pump a tire, as with most mini pumps it takes a while to get it up to pressure, purely due to the limited capacity a mini pump has. I realise this and expect it so it's no big deal.
It's a pump, it has pumped my shocks and tyres when needed to the required pressure and has not deteriorated or failed in the time i have had it.
Overall I am very happy with it.
Being a compromise, it'll never be as light and efficient as each separate item but it's sure lighter and more compact than carrying both. Horses for courses.
DudeistPriest, sounds like you got yourself a handy bit of gear. Hope it serves you well.
Here's the new pump and the pumps it's replacing:

For the weight conscious it weights in on my scales at 290g.
I've only used it on my forks so far and it works well though you do have to pump it like crazy.
Thanks for the IT fix Hawkeye.
DudeistPriest, do you mean it takes many pumping actions or is it hard to push the plunger in?
lots and lots of pumping, it's not hard to get the air in, it just takes a long time.
I pumped up a tyre today before heading out for a ride just to see how it works and like all small chambered pumps it took a while.
Nothing unexpected, as far as doing my shocks on the trail, it's as good as what I already had and it's only a backup for flats if I run out of CO2 canisters, so I think I'm going to be very happy with it.
Not sure if you will seat a tubeless tyre on a trail - not that you would ever need to.
I'd say not a hope in Hell.
FYI, I took the pump on a ride yesterday, fitted nicely inside my 2l Camelbak, could tell it was there but nothing overly uncomfortable, did 45km on roads, fire trails and single track.
Regarding seating tubeless beads, I always carry a length of thin nylon cord. Make a loop at one end and run it right around the wheel, in the center of the tread. Slip the loose end thru the loop and tighten it up until the center of the tread is really squashed in all around. That forces the beads out and it then only requires a small volume of air to get a seal and start pushing the beads in place.
Admittedly, I've never done this on the trail with a trail pump. But whenever I failed to seat the bead by pumping like a maniac using a floor pump and I resorted to the string trick (strap works too), all it then needed was a leisurely press of the piston on the floor pump to get a seal. So I feel pretty confident that it would work with a trail pump. The string weighs nothing and it can come in very handy in a lot of other situations, including fixing some mechanical breakdown and securing a couple of branches around your broken leg
