Ah right ok thanks, will that give me the missing travel back?

it should do yes.

I seem to be sitting at the 10% sag marker on my 160mm pikes giving less than 150mm travel

Flippin kipper moving the top cap spacer will not adjust the travel, the spring rod is too short. You need to contact Richard and ask him to send you the 160mm travel rod. The same thing happened to me, I ordered a 160mm kit and when I assembled it I realised I only had 150mm of travel. I emailed Richard and he has dispatched the 160mm travel rod. I haven’t received it yet but I have been running the fork at 150mm and I’m very pleased with it. It’s far more supple initially, has better mid stroke support, doesn’t have that “dead” air spring sensation and ramps up to full travel nicely. In short it feels like a smaller version of my Boxxer Team which is exactly what I wanted. Once I have the 160mm spring rod and have ridden it for a while longer I’ll write a proper report on here.

Thanks stompweaver, have emailed Richard and he replied saying to ensure the editing is correct (whatever that means?), but he agrees the overall length is controlled by the spring shaft so hopefully he can get a new one sent out.

Sorry to head that guys, but Richards seems a top chap though. He seems like an engineer that’s just getting used to the sales side of things, probably got a few rods mixed up in his workshop.

Hope it all works out.

Hi, thanks Tom – bit of an update, Richard gave me the length of the 160mm spring rod (213mm). I took it out and measured it and it was correct, this was also evident from the fact I could extend the forks 10mm or so by pulling them before the spring rod stopped further extension.

I then figured out there was quite a large 10mm gap between the top of the spring and air cap, even with the white preload spacer so the forks sat 10mm into their travel. To remedy I cut down an air token to fill the gap and now they are sitting at about 155mm available travel with just the weight of the bike. Hope that all makes sense!

The forks are a 2014 pike rc, maybe these have a slightly bigger air chamber than later models?

That sounds like the spring is too short!

Pretty sure that the 2014 pikes have no difference in air chamber size.

The later models have a different -ve chamber seal head but i think that’s it

The later models have a different -ve chamber seal head but i think that’s it Spring is 29cm long, bit I would have thought they would all be the same length as the travel only depends on air shaft length and the air chamber is the same size no? Anyway fork feels good, looking forward to riding it at the weekend!

Thanks for making this known Tom !

First ride out last night, so far so good, seems to work well with the charger damper.

Had a bit of a rattle round the back end though, this was due to leaving out the hub spacer on the cassette.

Finally received mine today after much waiting, my original order was lost/stolen in transit – Richard sorted this out with no fuss. Looking forward to getting it fitted up at the weekend.
Props to Richard for top service

First blast in the peaks since the mod was done, I can confirm they have passed 😕

What’s up with the confused emoticon then? 😛

This doesn’t sound right, my coil extended a good 5-10mm out of the fork so I had to press down on the coil before threading the top cap in.

Odd. Have you somehow ended up with one of the OEM 170mm Pikes making the rounds on the used market?

Interesting topic , Has anyone put a coil conversion in to a solomair yari and how does it work /will it work well with motion control ? Thanks

I’ve taken delivery of a spring set for a 160mm Pike just as the bleeding thing developed a creak from the CSU.
Will the kit fit directly into a Lyrik fork and give the same travel?

I’m not sure, you may be able to sell it on here or ask Richard nicely to swap it with a Lyrik model if it’s unused. Pretty sure the Lyriks have thicker stanchion walls – not sure if that will make a difference.

Have you tried re-torquing the top caps on both sides?

I’ve actually had a very quick reply off Richard about this, the Pike version will fit in Lyrik/Yari forks with an extra ‘wedge’ on top of the spring as the stantion is slightly longer. I was thinking that a bottomless token would do the trick with a bit of fettling.
I’ve not tried retorquing the top caps, I’ll give it a go cheers.

Try doing them up a bit tighter.

I’ve read this and Tom’s other review thread with interest. Currently have Pike 29 RC with 150mm travel. Used to have Pike 27.5 RTC3 with 160mm travel and the current RCs feel much more damped, certainly in the low speed department. I’ve got the dial as low as it will go and they still don’t feel anything like as supple as the RTC3s. Both are/were 2015 models.

Set-up currently is 3 tokens and 30% sag. 2 tokens with 30% sag wasn’t giving me the nice supple feeling and grip that I had on the RTC3s. Only problem is now (as indicated by a few here) is the less than satisfactory mid-range support.

So, you had me at hello…

The CRConception coil conversion sounds like it will make the forks perform much better. But, will I be better off going for less sag, say 25% rather than current 30%? A few here seem to run quite a low amount of sag, but I’ve been a 30% man for many years now. And how will I know what to aim for, or does Richard sort that out?

Thanks in advance…

Youre going to get less bottom out resistance by running a coil at 30 percent….so yeah I would highly recommend running a minimum of 25 percent. It wont feel much harsher on cobble type stuff as the fork will be more sesnitive. I dropped from about 23/24 to 21/22 and gained a bit more grip and reduced a bit of the buzz. Of course stuff that takes you into the midstroke may be a bit harsher as you have more support there although I havent noticed it – I suspect the fork is reacting faster and riding in a hugher softer part of its travel – whilst the latter third of travel will only have a little bit less support – given the drop in sag. So youll get a bit more blow off on really hard hits.

Ask around with some suspension tuners for advice though….eg Craig at Avalanche….hes a coil fan so may be able to help….if hes not too busy.

Richard can try and get close to the value you ask for – if not – I guess ask for his professional opinion on what will give you the best ride characteristics.

[list]If you really want to run 30 percent….and youre very particular about sag….Id suggest the virsprung mod plus a damper tune.

Again – Id recommend against running 30 percent sag though.

I don’t want to be responsible for making people spend money on something they arent hapoy with, coils are great if you can focus on ride chacteristics not pre existing ideas of what sag values should be.

I’m nowhere near as knowledgeable as Tom but I’d 100% agree that a coil with 30% sag would be bad. I’d put money on it bottoming out all over the place (based on being very happy with a coil in a 160mm 650b Pike at around 22% sag)

No, I get that, hence asking for a bit of advice, but will even 25% be too soft at the top? Think I’ll have a word with someone and get a better idea. Thinking of trying zero tokens this weekend to see what that does too.

Zero tokens will give you a better idea of how the fork will react with a coil – as you can run less sag to get the same bottom out and have more midstroke support. So you can find a sag setting which will be closer to giving you the desired bottom out on a coil spring.

However the midstroke still wont be as good, nor will the grip.

But it will give you a much better idea of what you might like. Just tryvto imagine what your setting would be like with a more sensitivy and support in the midstroke.

Aye, it’s my search for grip and sensitivity that takes me to 30%, but I sense some experimenting coming on. I’ve heard through a riding buddy the Jake at Sprung reckons zero tokens and 25% sag is the way for Pikes.

Cheers.

thats what ive just got after fitting a luftkappe, previously 20% sag and 2 tokens, without the luftkappe that woudve been far too divey

I found that with the FAST damper I could run 23/24 percent sag and one token (before the FAST damper I was running two tokens) – without the vorsprung – less sag didn’t have enough grip – without one token it was still a bit divey. But yeah, more linear with less sag and more sensitivity is the way forward I reckon – whether that means going coil or to a larger negative spring depends on what your priorities are – both systems have their positives and negatives.

Home made spring kit at 20% is miles better than air at 25-30% with or without tokens.

This is at 160mm, 650b chassis with 26″ wheels.

Rickos, the Pike RC compression shim stack is supposed to be much more restrictive than the RCT3 one, something to do with OEMs wanting the LSC dial to offer a complete lockout (allegedly). That might explain the differences you are noticing.

Ah, yes, that does sound likely based on my experience. Cheers, bacon.

Hello, i have been pretty disappointed with the conversion kit from cr conception. Spring weight seemed to be correct. Around 23% standing sag at 88 kg naked. Unfortunately i had harsh bottom outs on minor impacts. Pretty much only tolerable for cruising. In my opinion the coil conversion is not working due to the lag of a bottom out device (like the hydraulic bottom out of a Marz. 55 RC3 for example). I think the fork is just designed for the ramp up of an air spring. The top out felt pretty harsh too. Unfortanetly CRC refused to exchange spring weight after purchase. In fact there was no support at all. Messages are ignored meanwhile. Poor customer service and therefore absolutely no recommendation from my side!

is bottoming out even with the compression ramped up?

Yes, compression one click from closed (pike rc) and still bottoming

Yes, compression one click from closed (pike rc) and still bottoming

Are you sure your damper is in good working order?

Nope, not had harsh bottom outs. Probably need to get a lighter compression tune on my FAST damper and a faster end stroke rebound tune tbh – as Rick says – your damper is probably shot. The conversion keeps the standard rock shocks bottom out bumper assembly located in the bottom of the stanchion, doesn’t it? You filled it with enough oil?

One click from closed would have had my old RC pretty much locked out.

Shame to hear your messages haven’t been returned, but he barely speaks English – so hopefully a case of lost in translation. If however, he feels your damper is borked and he sends you a new coil – and that doesn’t help either – then that is a waste of both his time and money and your time. At least I hope that is what is going on – get the damper looked at.

Oh and

worth a read

Thanks for your opinion but my Damper is working fine. Oil Levels are as recommended and I tested the system in 3 different pikes. All the same. Cant be the dampers fault. Im now on a AWK double floating air chamber (similar to Manitous IRT). Best compromise between air and coil so far. Hate to say it but CRC is no more an option for me. And yes i think we understood each other quite clear.

I had a conversation about these springs with TFT when my forks were in for a service last week. They were less than complimentary about the build quality of them. They did say they would be offering their own coils conversion very soon.

You could argue that they were putting down another product in favour of their own but it didn’t sound like that to me.

I’m still waiting for the TFT option before doing anything.

So as I read it the CRC kit has worked for loads of people within this thread? But for you it bottoms out, your dampener is fine and you have tried on three different sets of pikes? Seems a bit weird to me.

The TF Tuned option has been coming out soon since last summer. The last launch was meant to be Sea Otter. Nothing wrong with the build quality imo, it’s simple stuff
