- Rear Suspension.
Ok this is a proper question. My bike rides as most 6″ bikes probably do and smoothes the trail a bit too much. As I have coil suspension finding this out will cost money so Im asking on here.
I want my bike to ride a bit more like a hard tail with the suspension there for insurance. If I get a heavier spring for general trail duties will the bike have less wallow and be easier to bunny hop and generally throw off small trail features or will it just be more bumpy and no fun at all? Obviously if I had an air shock I could just pump it up a bit or turn up the propedal to find out but I dont. And I know the thing to do is have one bike for everything but I just cant afford that right now so I want to see if my bike will do the job for now.Posted 9 years agoOllyMember
propedal SHOULD, do exactly what you want.
its stiff for general pedaling, but gives way like a softer shock when you impact something.
a stiff spring would certainly make the bike more hardtail like, but would also be more hardtail like on the downs, and without sufficient weight on it,it will probably spike quite harshly?
i would suggest an RP23 air shock, but as you say, quite an expensive experiment.
how about trying out (borrow or at a test day) a 6″ bike with propedal on it, to see how it feels in comparison?
what bike is it?Posted 9 years ago
I would like an RP23 but unfortunately I have a silly sized shock on my bike and they dont sell them in a size that would fit aftermarket but some Santa Cruz frames run a size that would fit so there is a faint possibility I could get an OE one.
My spring is the correct weight and my shock has been custom valved by TFT but apparently they cant put much of a platform on my shock because it doesnt contain enough oil so it would overheat. After tuning it was loads better and I can actually pedal up hill instead of bouncing up it.Posted 9 years agomolgripsSubscriber
Fox DHX air could help you. Tuneable.
I don’t think running it harder will help. Presumably you’ve tried increasing the preload on the shock by turning the collar? Of course, don’t to it to much as the coils get too close together which means that the shock bottoms out too early with an expensive bang. Running it harder will also give you less sag, which will in turn mean steeper angles. Which you might not like. If you had an air shock like the DHX 5.0 you can (I think) tune the spring rate – so you could have it quite soft in the first bit of travel, where you’d sit normally, and then have it ramp up hard at the end which could give you the firmness you are looking for.
You could try running with less rebound and then bouncing it to get into the air. Some bikes can be run very active without kicking you off big hits – like my 5. On the other hand, my GF cake, whilst riding nicely no normal stuff with the shock set really active, would really kick me up in the air on bigger hits.
To be honest tho, if you want a more hardtail feel you might just have to change the frame. A 6″ bike needs to be appreciated for what it is.. dig that smooshy travel, let rip on the rocks and aim for the bigger obstacles for air. When I’m riding mine, instead of plonking down the drops and over rocks I just hit them and fly. Usually the right way up 🙂Posted 9 years ago
You need to add some preload – is there a preload nut on the shock? Just wind some of that on and you should find that the initial force required to get the bike bouncing is increased, but the shock will still do its stuff and go through its travel when subject to a big input.Posted 9 years ago
The 5 does ride very nicely my mate has one and rarely lets me have a go because its so nice.
I do ride it like a big bike but it is my main bike and the normal stuff around here doesnt really justify 6 inches (mrs). Im trying to come up with a shorter travel solution and transferring all the bits from my seldom used Kona onto it, its going to be a bit of a frankenbike. The wife will then get the Kona after a facelift (the bike not her shes only 25) as its way too small for me.
MrNutt where can I get such a thing TF dont seem to have any.Posted 9 years ago
Sorry I_Ache – thought you didn’t realise. Adding preload will effectively use up the very soft initial part of the suspension – it is true that it is a somewhat crude way to tune but it is definitely worth trying because you already have it there and I’m pretty sure it will do some of what you are looking for. Certainly I think you’d be crazy to spend on something else without trying the preload setting, because it wsii so quick to try. And Free!Posted 9 years agowwaswasSubscriber
what you need is another bike as any sane person on here will tell you.
6″ bike for mucking about
4″ bike for getting the miles in.
you know it makes sense.
In reality I think you’re always goign to be hampered by the type of bike the enduro is designed to be (ie. it’s not a hardtail with a bit of extra cushioning for the bumpy bits).Posted 9 years ago
Be interested to know the result.
I don’t think a heavier spring will be ideal, because you’d need tons of rebound damping to keep it under control and your ride height will be increased even more than with extra preload.
Another suggestion (and this isn’t a joke!) – something as simple as using a firmer saddle will change your perception of the way the bike pedals, as will using slightly slimmer tyres (if your current tyres are big’uns).Posted 9 years agoAndyPaiceMember
I’ve got a DHX 5 coil on my 06 enduro, and the propedal doesn’tmake that much difference. I’m not sure however if my shock is set up for the enduro as it was a 2nd hand shock. even with the propedal on max it does still feel like a ‘big’ bike, it doesnt magically tun into a nice light and lively bike 🙁
I think anything with that much plush travel, and a frame that weighs nearly 9lb with a coil shock is going to struggle to be a lively XC/trail bike unfortunately. When I switch between my subzero and my enduro it is a big differnce even though the subzero is built up with similar weight kit.
I also tried running a higher air pressure in the DHX5, and it did stiffen things up, but it felt as if it raised the BB height and the bike lost the nice planted feel on fast downhills. The ride also became nasty and harsh.Posted 9 years ago
Oh I can justify a lot more than 3 bikes even if they only get ridden once a month each I just cant afford it.
Dont get me wrong the Enduro is fantastic at what its supposed to do I just want it to be able to be the light stiff flickable bike too thats still tough and will take the hits.
But I know it will never be that and I should just dig deep and buy another bike.Posted 9 years agomolgripsSubscriber
Just wind some of that on and you should find that the initial force required to get the bike bouncing is increased, but the shock will still do its stuff and go through its travel when subject to a big input.
I don’t think it works like that, unless it’s a progressively wound spring. If it’s not (I didn’t think most were) then it would just increase the rate across the whole stroke.
To be honest mate, you could get a 456 frame for much less than the price of a new shock, and transfer the bits. It’d be way nicer. You really can’t change a leopard’s spots that much. If you want it lively then you can save some weight on the bits but even then it’s going to cost you and it’ll still just be a lighter bike with 6″ travel. Won’t do what you want – just not designed that way.Posted 9 years agoTandemJeremyMember
Increasing preload cannot affect spring rate unless its a progressive spring – all you are doing is increasing the ride hight. a 120lb / inch spring is a 120 lb inch spring throughout its travel. Thats what spring rate means. every 120 lb of load on it it compresses an inch. Preload it an inch and it take 120 lb to move it off its stop. put another 120 lb on it and it moves an inch.Posted 9 years ago
I think anything with that much plush travel, and a frame that weighs nearly 9lb with a coil shock is going to struggle to be a lively XC/trail bike unfortunately.
I’d have to disagree there (sorry), my FXR is a 6.5″ single pivot and came with a coil shock (that I just swapped out for an air shock) and it runs rings around all the 5″ bikes I tried out (and there were a lot of them) pretty much everywhere. I think it really depends more on the design than the amount of travel. But that’s just IMO of course 🙂
If you’re just wanting a cheap(ish) air shock then the Manitou range comes in some pretty odd sizes so should have you covered and the SPV shocks are surprisingly really very good – and importantly very tunable.Posted 9 years ago
