Just wondering if anyone had any idea what the setting for this is?

Float RP2 DRCV (7.25x2.00)

2.25 seems right or close, but looking for some knowledge or advice as I haven't seen anything because of Trek & Fox's proprietary deal. Thanks so much and take care.

Do you know what year? I'll scrounge around tonight and see what I can find.

Hey, are you sure about that travel?

I found some RP2 7.25 x 1.75 and 7.50 x 2.00. No 7.25 x 2.00 though...

Well, well, well... I'm not sure I have your answer. But, I found something really neat. :D

I only have tech documents for Fox shocks up to 2009. I have the 07-09 documents online here: viewtopic.php?f=11&t=694

Take a look at that link and select a bunch of RP2 and RP23 shock diagrams to view. You'll notice the IFP depth (on page 2 of each pdf) varies by the amount of travel with no relation to the overall length of the shock. Makes sense if you think about it. I just never thought about it.

From all of the samples I viewed (probably about 30), I came up with the following...

{Length} x {Travel} : {IFP_Depth}
5.500 x 1.00 : 1.400
6.000 x 1.25 : 1.600
6.500 x 1.50 : 1.900
7.250 x 1.75 : 2.100
7.500 x 2.00 : 2.250
7.875 x 2.00 : 2.250
7.875 x 2.25 : 2.400
8.000 x 2.25 : 2.400
8.500 x 2.50 : 2.650
9.500 x 3.00 : 3.075

I'd feel very confident setting your 2.00" travel RP2 to an IFP depth of 2.250". :)

See, that is what I figured going through and bouncing off other 2.00 lengths RP2/3s. Not to mention, this is what I measured it at last time (wasn't sure if it was off a bit) and I tested that and noticed no lack in performance, considering the recent schrader valve mod and the service, it has performed better than day 1 it seems. Now, that I'm in my "winter inspection/lube/etc" and I'm changing fluids in this guy, I figured it would help to make absolutely sure. Only thing now, is I'm wanting to run Silkolene Pro RSF for the dampening fluid instead of Fox. Easier to get on hand and have read multiple posts on preference coupled with success. I know, I have preferred Mobil 1 for lubricating and it has been excellent in all conditions and temps as I ride everywhere year round.

I really appreciate it. Going 2.25 and if you have any alternatives to fluid/lubrication, I'm all ears. Thanks again and take care.

Mobile 1 is what I use for splash fluid in the lowers when working on sealed damper forks. Great stuff.

I've been using Torco RFF for most everything else since it's what RockShox uses and I can get it cheap from Amazon (free Prime shipping is the shiznitz).

For lubricating air chambers I use 5-10cc of 90w synthetic gear oil.

Roger that, I've read some using 80wt gear oil, but yea, 90wt certainly. Might check that Torco out. Wish I had it on me now, I'd do it while I'm away from home. Lol. Thanks again and take care.
