Any of the upgrade options out there that work with the Dual Position Pike?

Do you mean you want to keep the ability to lower the travel? If so, no there's not a coil kit that will currently do that

You could try to mod a Lyrik Coil U-turn spring. I converted a set of U-turn Dual Air Revs to U-turn coil using U-turn coil bits from an old set of Psylo SL's.

Only did it after I accidentally put a tiny scratch in the air tube.

As others have pointed out, try torquing the top caps up more to get tid of creaks in Pikes and Lyriks.

You dont want to needlessly slow the rebound down, you want it to stay higher in its travel and not pack down into its deep stroke brcause this means the fork is staying in the softer parts of its travel. Only slow it down to the point where the front isnt fighting you in rock gardens, pushing you out wide in berms or giving you a bucking sensation.

I use a bit more travel on single hard impacts, not much over a two spacer air setup. But in tock gardens I actually use less - despite the fork feeling more compliant - I can only assume the fork is reacting quicker and riding higher due to less seals and more midstroke support.

Be methodical with setup as well, try full slow and full fast rebound and move inwards, trying a click or two in from open and closed in an alternating fashion. Do this on a single track/section and note down what you notice about each setting.

I assume, given the free length of the spring, that it doesn't get close to coil bound. So, in theory, could I order a 140mm kit for ,160mm pike and put a 20mm spacer on top of the spring? Then, if I want to shorten the travel, move the spacer to the spring rod? Pretty much like the original Fox vanilla forks?

The theory there is probably sound, just so happen to have been reminding myself of how to lower an old set of Fox 125s the other day. No idea about the spring length part of the assumption though.

I do think you'd struggle to use the same spacer when you switch the travel though, as there's not much room to make sure you hit the negative spring

This is all purely speculative as I'm in the process of selecting a new frame, but an Airdrop Edit with cc coil IL is in the lead right now. Feels better with a 150 fork though.

I've been keeping an eye on the Super Alloy Racing 'PSP' coil conversion, apparently a press release will be out tomorrow, but release date likely not until spring, not sure I'll wait that long, I have a few more token variations to try and see if I can find what I'm after before I bite the coil bullet.
The hydraulic bottom out does sound interesting, but is likely to add more cost over a CRC conversion. Does the CRC kit have anything in the way of bottom out protection?

It alludes to it in the pictures - but I'm not so sure - it has something to do with that ring at the bottom of the lowers that is left in the Pike - it's the standard bottom out bumper I think. Maybe someone should ask Richard.

Although it wouldn't be hard to put an elastomer in there, like coil shocks have.

I'm looking forward to seeing this one, which I recon is the one TF are talking about:

Has anyone on here got a crconception kit to hand? I'd like to get the pike kit measurements, (spring length and also the lower leg rod length too) if it's not too much trouble.
Just want to compare with my lyrik kit.

Cheers

I put on a bit of weight last year, didn't bike much for various reasons, so I'm a fair bit heavier than I have been when I'm fit. I also often ride my bike with no rucksack and sometimes with a heavy rucksack for a big day out. So there's quite a variation in my riding possible weight...

I reckon that the lightest I'd be ready to ride is 80kg and the heaviest is 94kg.

Am i right in saying a 17.5% increase in riding weight = a 17.5% increase in sag (in mm)? So 20% (32mm) sag at 80kg = 23.5% (37.6mm) at 94kg??

Not unless you ride a unicycle 🙂

Though I suppose it will still be proportional so you could be about right

I'm tempted to try a DIY coil conversion using coil Lyrik parts. Have read on mtbr that it works, only sticking point would be getting the right length and rate of spring.

In my head I need a Lyrik 160mm spring shaft (cut down and threaded to give the right travel) 11.4015.421.020 (or a 170 cut down more), a Lyrik top out spring 11.4015.458.010, Lyrik spring sleeve to protect the inner stanchion 11.4015.205.000 and finally the difficult bit, an appropriate length, diameter and rate spring. I guess I'd have to fit the other bits then measure the spring length required? All the above parts excluding spring would be ~£60 then i'd hope I can get away with a cheap off the shelf spring

I would say that going from 20 to 23 percent sag is pretty unnoticable. 20 is still going to feel more sensitive than 23 with air and I reckon 23 with coil will still feel more supportive than 20 percent sag with air. I dont think that is enough of a margin of variation to outweigh the performance differences of coil vs air.

That's kind of the conclusion I've come to. I wouldn't want less than 20% sag or more than 25%. So the coil looks a goer now rather than in 6 months after I've lost a bit of weight.

No need to rush - lose some weight if you want and have the coil as a prize for doing so. Or if you do lose it and you find yourself wanting a new spring, I would say it would be quite useful to have two spring rates. One for racing or jumping and one for all day riding, seeing as the springs are so easy to drop in once the lower assembly is installed.

That's going to end up close to 100 quid isn't it. For not much more, you can choose out of 10 spring rates instead of 5.

I could probably save £20 and skip the lyrik top out spring and use the rubber one out of the Pike? Or, go full DIY and turn down the pike air spring piston diameter .5mm or so, bolt something through the top of the piston to make it a top hat shape to retain a spring and just find a spring and some acetate?

Joined the coil revolution today when I picked up a mint X-Fusion Vengeance....at 170mm travel I can't decide whether to run it on my HT to make a brute of a thing or stick it on the front of my Trance giving me an Enduro-tastic 170mm front and 156mm rear.....decisions decisions.
Also arrived today was a saddle weighing less than 100gms....gonna weigh the Trance later with its air suspension and see what I get, I'll be disappointed if it's over 30lbs.

Just by way of some proper feedback on the coil conversion.

Installation is fairly straightforward, so I won't dwell on that, relatively easy to do, just take your time and make sure everything is very clean etc.

Today was my first real ride in anger.
Rebound was a tad slower than I have had in the past, just felt a little better like that for me.

Sag is at about 25%, my Pikes have been altered to 140mm.
Played around with the low speed compression damping , couple of clicks out, about 5 from fully closed.

Impressed, much firmer feel without being harsh, doesn't go through the travel as easy, although I almost achieved full travel at 135mm.

The biggest thing for me is how much more in control and firmer the fork now feels.

Anyone sitting on the fence should really consider this mod.

I have another bike with a dual travel Pike on it. Will be doing this mod for the Pike, don't use the travel reduction thing anyway.

Any tips or feedback on the ordering process? The website looks a little light on info irrespective of the language barrier.

I emailed Richard directly, he was very helpful in pointing me in the right direction.

Just include the details of what you want in the email.

Ask for whatever info you'd like and I'd expect someone can help, there are a few of us have the kits now.

Edit: have you got the order spreadsheet? It covers all the detail about weight etc

So I went on another ride, this time with 0 tokens and 120PSI, it gave about 11% sag. Mid stroke was improved on anything I had when running tokens, and small bump wasn't [i]as[/i] bad as I was expecting. I certainly could live with what I've got, and my Lyrik is better than a friend's Pike, but I still think I'm on a compromise, and since there's a mod out there that will give me even more sensitivity with the support I'm after, and it's not super expensive, I think it's a no-brainer, so I'll be sending off an order form sometime this afternoon

Also when the install instructions say add 10 ml of oil, does it matter what weight oil is used? I have a bottle of Fox 10W Green and Fox Float Fluid hanging around in the garage

I stuck with the same rock shox oil I'd always use for a lower leg service

Given that the spring leg becomes one large volume, I guess the 10ml isn't that critical. I might be tempted to add a little more.

Ok late to this but, I've got a pair of 27.5/160mm pikes with a few scratches on the stantions and the damper has a bulge near the bottom of the rubber bellows bit.
Could these be used for a coil conversion or not???
Was planning to e bay as Spaire or repair but fancy try as coil if this is a possibility.

Don't see why not. The rubber bladder part of the Charger damper is available as a service item AFAIK.

I hope all the coil upgrades worked out well for you lot this weekend.

Hows the rattle issue legend?

I've just been comparing two FAST equipped forks, my coil equipped Pike and an MRP Ramp Control equipped air 170mm Lyrik. The difference in grip and feel is a little bit nuts actually - it's more noticeable when you go back to air. The longer legged Lyrik, has only what I can describe as a more rounded feel to the information that is coming through the bars - yet it doesn't grip as well on the wet hardpack on the steel city DH at Greno. The coil gives a bit more feedback (but not the kind of harsh feedback that causes hand fatigue) - and more grip, it's hard to say how much - but it is there and pretty obvious to boot. The coil seems to be better at keeping the front wheel tracking the terrain, whilst the air can feel a little softer until you ride through repeated hits where the fork doesn't react to the terrain as well.

The more I'm riding it, the happier I am.

I'm hamstrung by the lack of top cap at the moment, Richard can't source one, but ended an email with "stay tuned" whether that means he's got a plan to make custom machined top caps himself I don't know. I'm seeing if my LBS can get their hands on one.

Unfortunately I think it means I'll be riding BPW next weekend with air.

After running 0 tokens and 120 PSI to get mid stroke support this weekend, my hands were blown up and I was feeling the front wheel skipping instead of tracking. Might have to revert back to wallow-y tokens just for a bit of traction next weekend.

Coil can't come soon enough

No rattle, just a gentle occasional squeak. Have had the spring out, extra grease, flipped upside down, re-seated, etc, etc and it's still there. It's a non-issue tbh, think I only ever actually hear it on climbs. Also cant make it do it with the spring out, so 99% it's just flexing off the inner wall of the stanchion.

Let me know if Richard decides to make his own topcap though, I wouldn't mind one anodized purple to match my FAST damper...because...I'm a tart.

Tom, the lyrik uses a different thread pitch to a 2014-16 Pike.

Ahhh, forgot he had a Lyrik.

In that case

😆 😛

Not sure that's the right one though, googling the part number brings up images of a much older design.
