    scott ransom shock options ?

    can anyone recommend me a shock to replace the equalizer shock off a ransom 40 ?
    thinking of a fox rp3 or rp23 was told 190mm eye 2 eye x 50mm stroke would fit and perform better than the equalizer ?
    any pointer welcome
    cheers D

    Just wondering, have you acquired the bushings already or are you just thinking of doing this? If so where and how much? The only ones I could find were custom from UK at $70 each and you need four of them. I think there was another site a bit cheaper but still around $200 for all four and it was also in UK.

    Fox doesnt have bushings that will work? It would be a very simple part to make at a machine shop if not...

    I'm not sure if FOX offers the bushings for Scott. The online shops I found that have the bushings are in UK and were expensive but they did offer a custom choice. I doubt it would cost a lot less if I was to find a shop in town to make me custom bushings. I've always wanted a CNC machine though.

    they are not Scott specific bushings. the only criteria here is the right width. find out what width you need and call Fox. we're talking about a very simple part here...

    I ran a Fox DHX 5 Air for a while and it worked very well on the downhill stuff. I missed the lockout option for climbing so now I am back to the Equalizer. I would definately get a DHX air over a RP23 due to the fact that the more progressive you can set up the shock the better for this frame.

    Would you mind sharing where you got the bushings and the size?

    Thanks!

    They are a standard size from Fox. I can't remember exactly but if you measure the distance between the mounts you will be fine.

    No CNC machine needed - just a simple lathe like every high school metal shop has.

    I know somebody that can get you some bushings for $50 shipped if you really have an aversion to calling Fox.

    Thanks for the help guys. The shock's back at the shop right now and Scott's supposed to be looking at it. I have another bike to ride at the moment, so I'm still hoping to get the equalizer back on the Ransom; I really do like that shock.

    shock measurements

    I am looking towards the same route with changing my equalizer out for a DHX 5 coil. I wanted to make SURE that 7.5 2.0 (190, 50mm) is the correct shock length and stroke for our frames? Anyone have experience with the coil in the rear instead of air? Thanks a lot guys, looking forward to hearing some responses

    Did you finally change your equalizer by a fox?

    Hi

    I would like to refresh this topic couse my equalizer breaking to often. So I thought if it possible to install any other shock. As far as I'm concerned the lenght of shock should be 190 mm (one guy told me that 200mm also fits), bushings can be moved from Equalizer. Thing, that I'm wondering is how much pressure is needed in typical 190x50 (7.5x2) or 200x57(7.875x2.25) shock to guarantee proper work under 85kg (187 lbs) rider? Does anyone had experiences in it?

    Best regards and sorry for poor language

    Hey Jacek

    You would need to make a 190mm DHX air more progressive to get it to work well with the Ransom. You can get it tuned by someone or you can change the air can to a small volume RP23 by yourself. It is not too hard. There are a couple more things you could do but would need to be done by a suspension tuner.

    A coil shock won't clear the linkage. Air shock only and I have had good results with a DHX air.

    I wrote to guy, who built ransom with dhx5 and that's what he answer:
    I built Scott Ransom aluminium with a Fox DHX air 5.0. First impressions while trail riding were quite good. It was compliant, reliable, and not connected to my handlebar. However, on agressive compression the bike would bottom out. I cranked the bottom out resistance and eventually pumped the shock up to nearly 250psi (max:300psi rider weight:147lb). It would still bottom out hard. To understand the reason for this we have to look at the concept of the ransom. This bike has a reverse leverage ratio meaning the lever pushes with less force at the beginning of the shock stroke and the most force at the end of it. That features gives the ransom its firm pedaling platform and smooth midstroke. Virtually all other bicycles do the exact opposite to achieve a "ramp up" at the end of the stroke and prevent the bike from bottoming harshly. The continuous smashing took it's toll and over the summer I blew up the main pivot, bent three shock bolts, and smashed the bearings in the shock link. 3 weeks into September the bottom brackett almost tore off below the shock mount.
    Pros: can ride for more than 6 weeks without 2 week rear shock overhaul
    Cons: Piddly Ransom will smash to pieces
    bottom line: if your freeriding and under 6' get yourself the new Scott Voltage Fr. That's what I got and it shreds. If your looking for more of trailriding machine, just get a Trek Remedy.

    Sum: If you arn not lucky guy - don't buy this ****. You will lose your money and pleasure of riding.

    The DHX air needs a smaller air can and a bottom out bumper from a DHX coil on the main shaft. It is very easy to do and will get rid of the bottoming. When set up correctly it works great. A stock DHX air with a big air can will not work well. You don't even have to rebleed the shock to do the things mentioned above.

    So if it's that easy can you describe this operation precisly or post the link to some step-by-step tutorial?

    Thanks for answering

    Here is a tech video for changing the air sleeve. The DHX Air usually has a two chamber air sleeve and on the Ransom I find that the smallest volume air can from an RP23 works best. When you have the air can off of the shock you can cut a bottomout bumper off of another coil shock and superglue it back together on the main shaft to help ramp up the end stroke. The Ransom works very well with these two mods. The frame is too light to handle repeated bottom outs just like most frames.

    Let me know if it is not clear enough.


    This would be the easiest if that looks too complicated or if you are in Europe, Suspension Center out of Switzerland can do DHX air shocks for Ransoms. http://www.foxracingshox.com/protune/?utm_source=bignewsbike&utm_medium=banners&utm_cam paign=protunelinks



    Here is a shot of me road gapping my Ransom with a tuned DHX air

    Thanks for your support. I'm afraid that I can not afford to buy Float and dhx air just to make one shock of them. It is cheaper for me to repair the equalizer, then sell frameset and look for sth more conventional.

    You can buy just the aircan from a RP23. It is very accessible. Or you can shim the second air chamber to reduce the air volume with a piece of P-tex if cost is an issue. That is a ten minute process with little to no cost.

    It's an apparently cheap mod. $35 for the can and $6 for the seals. There has been a post about this mod already (not Ransom specific - just the can mod, no bumper mod) the poster included the part numbers too:

    DHX air upgraded with the RP3 air sleeve

    I have a DHX Air 5.0 with the can mod... ransom rides sweet.

    Now I just need to learn to huck like Bucko!

    I was looking on ebay and found this:
    http://cgi.ebay.de/FOX-DHX-Air-5-0-2...n%3D3%26ps%3D6

    As I see it doesn't need described mod. Am I wrong?

    You need the 190mm i2i shock and yes that is the aircan you need. The newer DHX airs like the one in the link work much better in stock form in a Ransom than the older ones.

    I have been offered a 2010 rp23 boost valve shock for a hell cheap price and was just wondering if that might work in the ransom with out any sort of mods.

    It might bottom out too hard and need a bit more progression.

    Just a question concerning the travel change when using a 50mm stroke shock (normal 190mm shock stroke) instead of the equalizers 40mm. Would that not change the travel accordingly to 50/40=+25% which would add 25% on top of the 165mm (1,25*165) making it an actual 206,2mm. Can the linkage really handle that and will not the rear tyre bottom out on the seat tube? What is your experience with this?

    My shock was tuned for the frame and had an extremely progressive end stroke. It was custom built and Scott does not recommend doing this. Mine also had extra bottom out bumpers on the shaft. I now ride the Voltage FR for that type of riding.

    My knowlegde is very limited so if someone can verify this or provide more accurate info please help us out...

    From what I've read the Ransom suspension design doesn't have a constant ratio (rear axle relative to shock stroke) throughout the travel. I remember reading on a mtb magazine web review that towards the end of the stroke the ratio is very high... something like 10:1.

    So the travel shouldn't be increased by 25% with a 50mm stroke shock. It should be much less than this. But the geometry of the bike is designed for 165mm of travel so will perform best with this amount of travel.

    I have a DHX Air 5 with 50mm of stroke but I bought the bike second hand (with DHX shock) from a person who works for Fox so I don't know what's been done to it internally (if anything). The bike rides well and has no issues with rockers, etc hitting and I've noticed that the shock never bottoms out regardless of how much pressure is in the main chamber so maybe the stroke has actually been reduced with bottom out bumpers too. I'm yet to let all the air out of the shock and see how much travel the rear wheel actually takes (and to see how much stroke there really is in the shock). I can do that if anyone's interested?

    I thought that the consensus was that there would be an approx increase in rear wheel travel of 10mm, making it 175mm of travel rather than +200mm.

    By the way, I set the sag at 30% based on the original 40mm of stroke on the DHX rather than 50mm because the bike wallows terribly and the bottom bracket is too low when it's set at 30% of 50mm of stroke.

    Oh you have a point there, the main rocker link is probably at the end of it's path at 165mm already so the aditional travel will mostly be spent out of the direction of travel of the shock. Am I right?

    Sounds like yours has the good tune. You wouldn't be feeling those things if it were stock. I ran the sag by feel of the suspension and didn't worry too much by the precise sag %.

    So...anywhere you could buy a DHX with this mod? I'm not up for doing it myself, but I'd gladly pay someone to do it for me

    To Suspension Center or DT Swiss? If you sent it to Suspension Center then ask JT about the Ransom tuned DHX air.

    Yeah, Suspension Center. I figure it's cheaper to get the Equalizer rebuilt instead of getting a new shock, but thanks anyway.

    New question here. Dhx air 4.0

    Hi everyone, I have the same problem, my Equalizer shock broke after three days of light freeriding (no drops). I found this Fox DHX AIR 4.0 shock, which seems to have a smaller volume one-chamber air can already installed from factory, what do you think?

    I know this is late replying to this but as long as that air can is for a 7.5" shock, then you're ok. But the problem with the DHX is you might end up bottoming out a lot more depending on your weight. The mid stroke damping, or lack of, will let you blow through the travel even if you max'd out the air pressure in the reservoir and have the bottom out dial all the way in.

    I still do although no real riding time. I'm currently waiting for Craig over at Avalanche to tune it for me.

    Consider getting an RP3 and have Push Industries tune it. I got off the phone with Craig yesterday and he told me for my weight (212lbs), I'll be pushing the DHX Air to the limit... to the point where it wasn't designed to work with a ridiculous leverage that the Ransom has. He worked his magic and should be getting it back next week. We'll see what happens. I might have to get my Equalizer rebuilt just in case my DHX Air takes a dump.
