What shock should I...
 

[Closed] What shock should I replace my Monarch with

My Monarch is leaking air, lost about 40 PSI on one two hour ride.

It's December....I don't want to not have a bike over Christmas....If I warranty it I'll probably end up without the bike at a time when I really want to get some winter riding in.

Should I:

1) Send it to TF tuned, pay for a service and hope I get it back

2) Put the money for a service towards a coil shock which I kind of wanted anyway and warranty the shock? Then have a coil shock for DH and an air shock for trails.

The bike I'm riding is a Nukeproof Mega.

If the latter, has anyone got a 200x57 CCDB they want to sell? Wouldn't mind a titanium spring, you can't get them for the Vivid and I can't afford/justify 700 quid for ti spring plus a new CCDB.

I might try that, it's just pressurized things even if they've been depressurized don't seem to mix with me. :mrgreen: They tend to go bang.

If there's an air leak it might be something as simple as a leaky Schraeder valve core...I've seen it happen before. Always eliminate the easy to fix before throwing money at a replacement. Chuck it in the sink to see where it's leaking from.

Cool, will try that thanks. I can't bugger it up by throwing it in water can I?

3) Quick fix while you source a ccdb, DIY air can seals for under £20 and reduce the volume of your air can while you are in there to make it more progressive. Inner tube, plastic shim or grease in the gap between the two sleeves does the job. This intermediary volume is unswept so at the end of the stroke. Lets you run lower pressure, more grip but better able to resist bottom out.

to give you a taste of how simple they are you can do this:
let the air out and grab the air can, un-screw it by hand and take a peek inside

Nah...It's designed to keep 300psi in and cold air out, so water won't do it any harm.

Slow typing tonight...

Full manual online, strip down of air can is easy, just don't depressurise the IFP without obtaining the correct pump adaptor first.

The rock shox vid says that you should depressurize the IFP before taking it apart.

Isn't the IFP pressurized with nitrogen? What's the standard pressure on the Mega for the IFP? Secondly what should I use to fill it with nitrogen again.

Sounds like a lot of hassle imo and I've just seen a Vivid for 240 euro's which is sorely tempting (despite the lack of titanium springs available for them) as I guess the weight wouldn't matter for when a coil shock is called for.

If you are only doing an air can you don't need to depressurise the IFP, it is acting inside the sealed damper.

Use air, it's 78% nitrogen. If you are worried about moisture, pump it up the car with aircon running 😉 Needs 250-350psi in there. But you don't need to touch it if you only do air can.

It's less hassle than drilling holes in your frame to fit a Reverb stealth! 😉 Certainly less than £250 worth of hassle for me, took about 30 mins.

Depressurise, unscrew air can by hand or possibly strap wrench, pull and replace the seals, screw back on, pump up. Great if you want to learn how a shock works and what it does too. Loads of tinkering potential.

The ifp on the monarch can be filled with air - you will need the adaptor though. You can strip down without depressurising the IFP- I believe!

KK, I'll try this - although I reckon I still want a coil shock as well. I've been on the fence for months about it, I think this is the final straw as I don't want to have to do this in the Alps next year. I think I'd have a hissy and would be very tempted to through my bike off the side of a cliff if it died at 3000m.

Thanks guys, you're loads of help! I really appreciate it.
