Should You Put A Coil Shock On Your Trail Bike?

[@ish474]

makes me happy I didn't buy a coil. When I go to the bike park I get in my head about getting one. But, I only get 1 or 2 bike park weekends each year. I prefer the pop and support of my Air shock on the stuff I ACTUALLY ride ,vs what I want to be riding. Sometimes that is a hard perspective to keep.

[@DazzaDirect]

i used the ACTUALLY method for my tyre choice , watched a video that said buy tyres for 95% of your ride, still ended with Marathon Plus MTB rear and Magic Mary front , GMBN is an amazing channel though ;-]

Coil is good if you like to ride some rough stuff, downhill tracks etc and thats it.

[@ebifurai415]

i have coil and i ride it everywhere. no reason you can't put a coil on a trail bike.

[@ish474]

@@ebifurai415 I totally get that. But I am a rider that has the biggest volume spacer and my sag set at 25%. And I also just built a hardtail. So for 90% of the stuff I ride I'm looking for the poppiest firmest backend I can get away with. But like I said when I'm riding fast downhill bike park stuff I really do long for that downhill bike feel. But I'll ride any bike anywhere I can, it's always fun!

[@SnowShackboy]

Got offered a killer deal on a new Push Elevensix and couldn't say no... so far Im loving it and super impressed on how I can tune it. The shock really doesn't suffer from a lot of usually drawbacks that affect most coils. Its set up to lock out perfectly and improves my climbing better than my dpx2 or RS super deluxe. Super fun through the chunky sutff and jumps too. Very impressed so far!

[@neildaniel8232]

I've got both types of shock for my trail bike. Air for normal rides and coil for uplift days, takes 20 mins to swap them over and essentially means I have 2 bikes for the price of a shock!

I recently fitted a Cane Creek DB Coil IL to my Cotic FlareMax, just to experiment. So much more grip, that "glued" feeling, but does feel like it sits back a bit compared to air. For what I ride, coil is the better option. If I were to do more jumps, I'd switch back to the DBAir IL instead. It's great having that option, takes 5mins to swap the shocks over.

Excellent presentation. My take on it: the bigger (rider, travel or terrain) you go, coil performs better. Conversely, the smaller you go (rider, travel or terrain) air will perform better.

[@mrvwbug4423]

As a bigger rider myself, I'd add the caveat that in general a bigger rider wants MORE progression on the back end not less. I actually put a cascade link on my bike to increase the progression curve, which allowed me to drop from 5 volume spacers to 3 on the air shock. I also tend to prefer a poppy bike over a planted one, so personal preference.

[@robvanduren761]

My bike is now rideable with a coil. Heavier and faster riders need them. Also can't understand the poppy /lively bullshit. People from Moto background will tell you a poppy bike will throw you off the track into a tree and kill you. To much fashion and not enough factual data.

Citroen cars used gas pressure spheres acting as springs. The sphere had a diaphragm across the centreline (equator?). Top was gas pressurised. Bottom contained hydraulic oil. Damping provided by valves in the bottom of the sphere. The oil was pressurised by the suspension strut underneath allowing ride height to be adjusted. Only one seal (like a bike coil shock) but on the fly ride height adjustment and the gas spheres added zero unsprung weight. Check it out.

[@nathanb101]

I’m running a progressive coil on my Santa 5010 at 100kg rider weight. Absolutely dialed - plush but poppy - coil on trail bikes for the win. Have own both air and coil on many bikes - will not purchase air anymore

[@ABHORRANCE831]

Which coil shock do you have on the 5010?

[@waynephilbert]

Coil shock performance as you state depends massively on the bike you fit it to. I've compared the same version (Cane Creek Kitsuma Air vs Coil) on my bike and very much prefer the coil everywhere. It doesn't compromise climbing in any way. The lockout, if you want to use it, is almost hardtail firm, and the descending performance is just stellar. Well worth whatever weight penalty there will be.

[@sageambrosek5206]

I weigh 260 pounds of mostly muscle and I can confidently say that bike weight matters very little to me. But when my 130 pound girlfriend is riding my overbuilt steel hard-core hardtail the weight does have a noticeable effect. I think weight as a proportion of total weight of rider and gear is far more useful than just weight. A half a kilo spring on a coil shock is just half a percent of the body mass of anyone over 100 kilos or 230 pounds.

[@MichaelAverycarhauler1969]

Bought a Push 11.6 on sale last year for my Ibis Ripmo AF. Bike originally came with a DVO Topaz air shock with Ibis' "traction tune" which lacked any support deeper in the travel from mid-stroke to bottom out, regardless of air pressure, sag %, volume spacers, or bladder air pressure. The Push 11.6 changed how the bike rides so dramatically that I don't think I'll ever ride another air shock. It climbs better, it descends better, it eats the gnar, chews through chunky tech, and begs you to go faster than you probably should. And this is on a bike that most people will tell you is too linear with it's 19% progressivity throughout the travel. On a bike known for it's climbing prowess with the DW Link suspension. IMHO the Push 11.6 is THE WAY on the Ibis Ripmo, period.

I first tried a coil a couple years ago on my Niner RIP 9 RDO. I could never get the stock DPX2 to feel good on choppy fast terrain with lots of continuous quick impacts. Once I put on a coil, the bike was transformed and was light years better everywhere when traction and control was needed on rough terrain. I never noticed the extra weight climbing and it only lost a little pop on jumps compared to air. I love the coil so much I made100% sure my new bike was designed to accommodate one. I do run a air shock on my 2021 Stumpjumper, which I use on smoother and less gnarly trails where the air shock still shines.

Coils are great. They're smooth as butter to the point you can't even feel the trail, you don't have to pump them up and they're always consistent....but I only use them for downhill and freeride. You lose so much energy pedaling as the coil absorbs everything, including your energy. So much more of your energy goes into spinning your tires and you get a great platform with an air shock at the expense of small bump sensitivity.

Doddy, nice to see you riding :) It is very unusual to see you riding in last videos.

I think each rider should choose what serves their purpose.

[@bradholmes4]

I went with a air shock when I upgraded my yeti sb130 to the lunch ride edition. Ive got fox factory 38 and float x2 giving me 160/140mm travel perspectively. the yeti's in general have a more linear linkage system with the switch infinity link so the air shocks balances that out quite nicely although you can easily get a 210x55 eye length coil shock in there. Heres the contraverial thing is that I race that bike myself being 6'6" that's 198cm for you metric people out there. I love the bike and although the sb150 has 10mm more travel my bike suits me well for racing because I can ride it on everything every day. not saying you cant do that on the 150 but the 130lr gives you a little bit more of a lively feel and makes you work a bit harder on your skills on the bike instead of letting the bike do the work for you. its fun for me might upgrade my frame sometime soon but for now I love my bike and it's great at the races!

How about maintaining both shocks? Is air less reliable and does it have to be rebuilt more often than the coil?

Do you think having a coil fork would better match the coil rear since both would sit into their travel more (compared to air shock/fork). If both fork and shock remain balanced, the geometry should be more stable.

Provided the suspension progression rate was sufficient for a coil, wouldnt it work better for heavier riders rather than having to run at or near max pressure in an air shock to set the sag to spec?

I weigh 250 pounds and the 500 lb coil is far better on my santa cruz bullit than all air shocks I have had for the last 2 decades on several other bikes. I would need to push the air up to 300 lb ( shock limit) to get the sag right on my focus jam 2 and have to check it every ride because it never would hold that high pressure ( drop 10 lb in two days) reliably for more than a day or two since new. same on Focus with Rockshox deluxe, Trek top fuel, SC tall Boy and Haibike all mt 7. I had max air spacers in it and i bent 3 pedals and 2 crank arms with pedal strikes in 2 years due to sagging rear end on big hits. the coil shock is far superior supple feel and not bottoming out or sagging & trolling for pedal strikes. I will never go back..

All very well for factory supported riders who can endlessly test at each round and have the factory play around with multiple springs to find the perfect one for the riders weight. Joe public need to know just buying a coil shock doesn’t mean it’s automatically going to be better without a lot of messing about. Then you go to the next event and repeat that process all over again. Rider weights dint change but how the spring reacts to the course does. And for that, you need support.
