    Really easy to install as long as you have the correct tools.
    Feels very nice so far but only riding outside of my house – maybe need the 40lb spring instead of the 45lb – There is one issue but I’m not sure whether it’s normal or not until I’ve spoke to TF or Vorsprung tomorrow – there is a noticeable topout knock/noise underlight movement of the fork, this is not noticeable once your full weight is on the bike and you are moving. Slowing the rebound to too slow does not remove the noise but full rebound damping does clear it.

    Any ideas greatly received 🙂

    What’s the top out spring like? Don’t think I’ve noticed it in any photos

    Quite small, you can see it on their website.

    How many preload washers have you got on the spring?

    two x 20mm = 40mm for 170mm travel
    Just added the 2mm x 2 to see what happens – it’s the same.

    You got the 9mm of shaft showing when you fitted the spring?
    If it doesn’t top out when you’re actualy riding is it a problem?

    9mm showing, not noticeable when riding.

    I’ve seen the video in pm, likely it’s a blown shim or leaky damper looking at the rebound speed at 6 clicks from fully closed.

    Not a real problem then.
    Coil forks are always a bit noisy.
    Edit.
    Not seen any of that so my comments are pointless.

    They don’t visually top out that loud, it’s as loud as my PUSH when I open the damper fully – but at 6 from closed. Fully closing the low speed ports fixes it and finally slows the fork downn, but the setting at 6 from fully closed is crazy fast to me. So IMO, bent high speed rebound shim.

    Raybanwomble – Thanks for your thoughts on the video I sent you, just got a reply from Steve at Vorsprung (great customer service on a Sunday!) so a few things to check with regard to pre-load etc. Will let you know result 🙂

    Interested how you get on with the 45lb spring, I was unsure between the 40 and 45 but went 40. Waiting for some tools to arrive in order to assemble mine.

    TF tuned via email seemed to suggest that the spring alone weighs about 400g so 600g extra weight all in fitted to the fork

    Minus about 100g from the the airspring – which is what my 170mm Fox 36 air shaft weighed. The Spring kit for my ACS3 weighed 400g as well but only added about 300g to the total weight. The extra oil will of course add a bit more.

    250g to 450g of extra weight depending on the spring rate sounds about right to me based on my experience with the ACS3.

    45lb spring in the bag is 337g.

    Anyone got a 29er 150mm debonair shaft they’ve taken out they want to sell?

    Needs to be 100% scratch free obvs.

    how is it? mini review?

    So, it’s sorted now! Very critical that you do not pre-load the spring at all, just snug the spring collar up to the spring to stop any vertical movement, the spring can move laterally on the collar and spacer but that’s not a problem.
    Feels very smooth so far but I’ve only managed a blast round my cul de sac 🙂

    Will report again once I’ve been into Wharny.

    Think I may need the 40lb spring not the 45lb I ordered.

    What grease did you use for the spring? I’ve got sram pm600 military grease which I’m hoping will be ok.

    I used SRAM Butter, you don’t want anything in there that may swell the seal, bushings etc.
    RSP stuff for forks from TFT or the recommended Slik Honey.

    Anyone else keep reading the name of the product as ‘spamshot’ ?

    I’m really liking mine after a couple of rides. A bit of noise from the spring but grip is fantastic and fork feels really plush.

    Really pleased;

    Much more comfortable through rocky sections, as I’m able to run less compression damping but able to control the amount of travel used off drops and heavy landings with the “Bottom out” adjuster. Plenty of mid stroke Pop for hitting jumps as well – can’t go wrong! Haven’t noticed the weight increase so far to affect my enjoyment of trail riding.
    Got a bit of noise from the top out spring preload but that’s getting cured – Steve at Vorsprung has been great at responding to questions and setup and TF are providing their usual excellent service.

    Get one – forget the weight increase, it’s the ride characteristics that count.

    cheers. I have got one, just not fitted yet!

    cheers. I have got one, just not fitted yet!

    Before assembling the parts(and covering the shaft with heat shrink) pay particular attention to the preload on the top out spring – make sure the top out spring turns easely, otherwise you’ll need to fit a different preload spacer to the top out spring (a kit will be available from TF very soon). In the meantime making sure there’s no preload at all on the main spring reduces the noise/clunk to hardly noticeable.

    I think I may well fit one of these to my Hightower soon, £100 less than Push makes it more appealing, though it’s about 140g heavier than the Push.

    My 29er came with 150mm forks rather than the standard 140mm, so I may take the Smashpot as an opportunity to set it to the factory 140mm to see if it makes the bike more manageable on steep technical ups. Easy enough to set it back to 150mm with this kit if I prefer the longer travel.

    @cyclelife someone else is fitting it for me 🙂

    To be clear for the others, I did not think that the top out on your fork when I tried was any worse than my ACS3’s – you hear it if you depress the fork a few mm but not after deep compression.

    how are we getting on my smashpot brothers and sisters?   I’m taking mine for a super quick test on saturday morning before leaving for finale where i can really test it.

    Anything to think about? How many clicks from fully closed are you running for bottom out? and changes to other settings? any changes to tyre pressure? Damper settings?
