Hello, I have bought a prophet and looking to replace the rear shock as it is leaking air.
I fancy a upgrade to the 8.5x2.5 float R, I know it will fit but how will it ride? At the min i have a 110 lefty on the front....
Should i just stick with the current 7.875x2?.....
Regards
Stick with the correct size and fit a RP23.
That's what I did and it made a huge improvement to the rear end.
Like this one?..............
Actually i think this is slightly shorter?.........
No the standard one without the boost valve.
Shock size for a standard Prophet is 200x50, and for the Prophet SL 190x45.
If you search the net there are examples of people using non standard sizes but when I swapped my original Float R for an RP23 I stuck with the standard length and stroke.
And from the research I did Prophets work better with a standard volume air can rather than a High Volume one.
Ok cool, Sorry for sounding a bit dumb but what exactly is the difference between the R and the RP23......
Is it a stiffer shock?
Regards
Float R you can adjust the rebound damping and it has fixed Pro-Pedal.
RP23 has adustable rebound, but you have a choice of 3 different levels of Pro Pedal and you can also turn the PP off by flicking a lever.
OK, you sound to have bought a Prophet [b]SL[/b]
This was the European (only I believe) 110/120mm short travel version of the standard 140mm Prophet. The only difference in the frame where the shock size, though obviously a shorter travel fork was fitted to the SL too.
So for ref:
STD Prophet Shock i2i: 200mm x 50mm stroke
Prophet SL shock i2i: 190mm x 44mm stroke
and as Simon mentions you need a "std can" not a "high volume can", as the Prophet suspension is a falling rate type, these can's aren't that expensive to replace if necessary (£30 IIRC)
Now people have fitted 225mm x ?? shock to Prophet frames but you may not be able to use the FR suspension setting (the better of the two in my book), and need to watch you rear wheel doesn't hit the seat tube at full compression.
Obviously I wouldn't rush to upgrade the rear shock length until you have a matching or simialr travel front end.
Personnally I do mean to try the shorter shock on my frame at some point, for a more taut feel, as most of us (well I) don't 'need' 140mm travel for UK riding.
BTW, what shock do you currently have?
As a £25 air seal kit maybe all you need (for a fox shock), though even a good service and minor tuning will be significantly cheaper, than a 2nd hand shock that may well also need servicing.
Air can service is a relatively easy DIY job. Utube is your friend.
Z1ppy speaks lots of sense. Don't be tempted by a high volume can - it's not an upgrade and would make the bike whoosh through the travel way too easily.
Thanks for all the help, i have took the shock apart and noticed a crack in the white plastic which the rubber piston seal sits on, Could this be a cause of pressure loss?
Regards
Assuming it's a fox .. this is an RP23 service vid but the principles are the same for most fox air shocks:
Yes its a fox r shock, does any one know if these White sleves are included in the seal kit?
Cheers
watch the vid & see? (he does a full disassembly and re-assembly)
Cool,thanks!............... 😀
