A couple of weekends ago I was out in the Pentlands when the rear shock (Cane Creek DBinline) got stuck fully compressed. The guys at the bike shop sent this off to Cane Creek and the shocks internals / seals were updated. Good news  . As the shock had been updated I needed to set it up again to suit the bike so I opted to start with the tune recommended by Cane Creek for my frame (Medium Banshee Spitfire) taken from their tuning section on the website. I also set the air pressure on the shock to what I thought was correct (around 145-150psi). I was out at Glentress on Sunday and found the shock to be bottoming out. I upped the pressure to 170psi ish and this helped on the rough stuff. I am inexperienced when I comes to suspension tuning / setting on bikes. My question is, does anyone have any tips or advice for setting suspension? Any advice would be appreciated |

It's not exactly scientific this ...but as a rough guide...
I have a fox shock with an o-ring around the "shaft" as a rough guide I was told that when sitting on the bike stationary ( get someone to hold it ) ..the o-ring should move about a third of the way down ...
Precision eh !?

Sorry I should of mentioned that I had set the sag previously at 15mm. Not sure if that helps.
After I set the pressure to around the 170psi mark it wasn't bottoming out. I'm just not sure if this is the correct way to solve the bottoming out issue.

Short of anyone else being able to answer that ..I will find out ..but it will possibly be weds evening before I reply ..
It's probably what I would have done though ..not that that's any real help!

Usually you would measure the shaft length with the o ring set right up to the air can, write this figure down, then sit on your bike with the kit on that you normally ride in, camelback with water in etc, get off the bike then measure where the o ring sits on the shaft, this should be between 20-30% of your first measurement depending on how you like it to feel, obviously if you run this setting nearer the 30% then you have more chance of it bottoming out but on this shock you have low/high speed compression damping which should help with bottoming out issues.
Setting up a shock is really down to individual preference, some like it firmer which would usually require you to put more air in

Hi Dan.
You could try increasing your High Speed compression That should stiffen up the stroke during those high speed hits. Do you know how many spacers are installed in your shock?
Not sure how much the below will help you but it may give you a rough idea of what to tune your shock too
Banshee Spitfire Inline setup Jul 3, 2015 2:40pm | Mtbman1980
| Banshee | Comments: 4
ve a couple of questions regarding the inline shock that came on my banshee spitfire.
I was reading the tuning setup for my bike and it said that I should install 2 spacers in the air chamber. The bike came with 2 spacers one large and one small and I just wanted to confirm that is what I should put in or if it should have come with 2 large.
The second part of the question is if the spacers are the correct size should I get a second large one as I quite easily reached full travel with the base tune setting and sag set at 30% or should I try increasing air pressure(decrease sag slightly) or increace high speed rebound a bit.
I am a large rider 220lbs no gear and I ride pretty agressivly.
Thanks for your help

You want to keep sag at 30% and control the spring rate using the volume spacers. Have you opened the air can to see what spacers are currently installed?
July 15, 2015 9:48pm by Mtbman1980
There were no spacers installed at first but I put in both spacers. Should I add an additional small spacer until I get the ramp up I like? The shock feels great except the fairly firm bottom out.
July 17, 2015 9:23am by CaneCreekCyclingComponents
Yeah, you may want to go to 3 large spacers for that bike. I've got the same bike and at 140lbs I have 2 large 1 small to control bottom outs.
My tune is 15mm sag
HSC - 1.5
LSC - 11
HSR - 2.0
LSR - 9

Thanks for the help and advice on this one. I have been looking around and reading up on this however I thought it would be best to ask as well. I will take a look and see how many / what spacers are currently in the shock. I will also increase the HSC a little. I plan on getting out to Glentress again this weekend so I will be able to get a good feel of things then. Cheers guys . |

Precision eh !? It's 20% sag of maximum travel, this has to be on all shock settings for example trail and descend on fox.... pressure settings are highlighted on the Manufacturers website, Cane Creek have a large database containing setting info and tuning. Sag needs to be set at full rider weight including helmets and backpacks. |

To set up my suspension, i set the air to the recommended pressure for the fork and shock, which being Rockshox, was printed on the fork, and i found the shock data online.
Then i set the rebound to the middle setting (counted the clicks)
Next up, i went to this local trail. Its a short run, about a minute long, and has everything. A pedalaly start, some varying corners (berms, flat and off camber) , plenty of roots, a few jumps and a couple of small drops and bombholes. I session-ed the trail, done a fair few runs, and each time i made small adjustments, whilst recording the changes so i could revert back if needed.
That way, i got them running a fair bit better than the standard in the garage technique which most people do! I still havent got them performing how i want, fork bottoms out way to easy (its way to linear for my liking), and the rear shock has too high compression tune, so i cant bottom it out. I have to drop the pressure ridiculously low, like 40% Sag, to get it anywhere near full stroke
Ideally id go for a coil rear shock and Fox 36 forks but im not made of money!

I'm too heavy to run 40%.. I'd trash the shock or forks..30% perhaps.. but I'm no hard hitter at 20% I use the majority of travel... |

Its sitting just below 30% at the moment, and its working alright, however the only time i've got full travel out of it at that sag is when hitting a fuck off drop and also when i cased a jump pretty hard. I think its down to the H Compression tune, im not heavy, something like 11 stone, so maybe a medium would have been better on my bike... If you're like me and into the technical side of the suspension, some Portuguese chap has uploaded loads of videos on how the different settings work, and compares the different suspension designs e.t.c Was quite an interesting watch |

I'm 17 stones.. tried a few variety of setting methods..manufacturers guidance and YouTube.. plus other riders settings... I'm happy with a general set up... not a specific discipline set up, such as a DH set up. I'm able to ride everywhere with this general set up, ND it feels adequate to me... being not the biggest of hitters... I think I manage with it pretty OK.

Thanks for the comments troops, with being new to this game the comments have helped to gain confidence in setting up the shock as it was a bit daunting to start with. I have been out on this shock at Glentress twice now and I feel I am getting to grips with it. I still want to play with the settings more (HSC) but I feel that I have a decent starting point now regarding air pressure. Thanks for the help on this one |

I'd love to know a bit more about all this setup malarkey as I have to admit to being a bit in the dark about it all.
Anyone got a 'Duffers Guide" link I could check out that covers the basics with further links to more advanced stuff? Just a general overview of what impact changing the settings should have. I've googled but there a million links and my little brain gets a bit overwhelmed!
TIA
