 Posted: Sun 22nd Jun 9:50pm Post subject: Manitou Swinger Spv 3way - Can I Shorten The Travel? |
  |
|
Hi!
Just a query to all 'rear shock' tech gurus. I have a giant reign 06 with a manitou swinger spv 3way. Is there a way I could shorten the 6" travel to say 3"-4"? Can I change the rear shock? Can a fox rp23 fit straight in it without changing the bike geometry?
Many thanks!
Cheers!

No. You would need to change the linkages rather then the shock to do that.
Why would you want to

You could possibly fit a shock that has a 200mm I2I on the shock, but only has a 38-40mm shock stroke on it to shorten the travel down to 4"
(if such a shock exists
Otherwise, it will only alter the geometry of the frame.

Similar to what Bob has said, use the existing shock in the frame, but get a bottom out spacer installed inside the shock on the internal shock shaft. This way you would keep your existing geometry, but shorten the stroke to 38mm instead the factory length. [edit] You would need to get a suspension service guy to install it for you; as it will require stripping down and servicing the shock to fit it.[/edit]
BUT why would you want to do that, sure you'll have the same travel as a Trance, but the weight and geometry of the Reign, turning your bike into neither

It was just a wild thought  ...
Thank you for the replies...Cheers!

You can fit a RP23 to an '06 Reign in place of the Swinger but it needs to be the same 200x50 dimensions (actually 7.875" x 2.0" in the case of Fox). Definitely improves the plushness of the rear suspension substantially. I've seen pictures on MTBR of people sucessfully fitting a 'zocchi Rocco air with 2.25" travel giving 6.75" at the rear wheel. Picture of my '06 Reign with RP23 at the link below:

and also it of course requires all new shock mount hardware (since the manitou is 12mm bore eyes and the fox 1/2")

is this just to make it feel more 'xc' - if so just change the shock pressure to run less sag (which in turn will up the spring rate and make it hard to achieve more than 3-4" travel)
or are you thinking more of trying to lower the BB / slacken the head angle

I was fortunate to acquire mine with all the hardware to mount to a Reign (second hand of Monolith's '07 Reign frame he had the off on and severly dented the top tube) so it bolted straight in.

I still say no, mostly due the harshness it would bottom out with and would guess that you would start breaking things.

Thanks heaps for the pix! And yes I was thinking maybe I could make it more enjoyable for xc as well. Is it ok to ask where you purchased your rp23 and had it installed? My email is: thy731[at]yahoo.com
Cheers!

Ooops! sorry i didn't see your follow-up thread...
Anyway, so does that mean I can just buy an rp23 and bolt it straight-on?
Thanks again!

I guess you've never opened one up then?
The bottom out out pad on all air shocks is only a couple of millimeters thick (thin). This is because of the air spring naturally ramping up in pressure during compression.
So because the shock would be set for 4" travel as opposed to 6", the riders air pressure would need to be increased to get the desired sag for a 4" bike; which inturn will create more bottom out resistance.
I would rather bottom out an airshock than a coil over for that reason. Bottom out is no where near as harsh on air.

any shop can order you an rp23 - rrp is over $600 though
you will need new hardware - either your local giant dealer should be able to source it (standard and consumable part) or rick at krankin.co.nz can supply them (he also has good prices on shocks)
most people going to fox's from swingers are looking for a plusher, more freeride feel (as opposed to the inherent platform of a swinger) - so if you're looking for a more xc ride it may not be what you want (unless you're wiling to live with the rp3 set to max propedal - which I personally hate the feel off).
have you tried just upping your pressures front and rear to give 25% sag - on my reign, running xc sag it feels very xc (though of course it still weighs a non-xc 33lb)

No I have not pulled one apart. Sounds like the bush goes in different to what I thought it would.
