Persist Fox 40 Crown and Integrated Stem

Feb 24, 2008
by Mike Levy  
To say the Fox 40 is a popular fork would be a touch of an understatement. The crew at Fox had a hit on their hands right out of the gate and have made only a handful of small running changes each season to keep it working like the champ it is. For whatever reason, one thing the 40 has never had is an integrated top crown and stem in stock form. Thankfully there are people out there with the incentive and know-how to deliver the goods.




Persist is a UK company that is producing a jewel of a crown for the Fox 40. Checking it out on their website had me thinking that if the guys at Persist think something is worth doing, then it's worth doing right! I was convinced of that fact when a tidy little brown box was delivered to my desk one afternoon. Sleeping in a bed of wood chips was the new Optimus top crown/stem combo.


You don't need me to tell you that this bit of bike kit is ridiculous, just look at it. There is no shortage of companies putting out after market goods for your bike but this thing looks to be straight out of a dirt bike catalog. The CNC'd crown and stem are made from blocks of 7075 T6 aluminum and anodized your favorite color, black. As if it wasn't trick enough to begin with Persist installs twelve gold titanium cap head screws instead of the boring steel versions that merely do the job. The 'goldanium' screws are nearly half the weight of their steel brothers, but far more importantly is the fact that they look great against the anodized black aluminum.


Each stanchion clamp uses two screws instead of the stock versions single screw, as well a much larger clamping surface area. This can only make for a far more secure arrangement and prevent the dreaded 'stanchion slip' that can happen on the biggest of big hits. The crown and stem are two separate pieces with the stem being attached via two screws from underneath the crown, as well as an additional steerer clamp screw. There are no reach adjustment options. This may put a few riders off but I can't think of many people that don't run 50mm stems on their DH bikes anyway, which conveniently is what you'll get with the Optimus. It also gives it a very clean look with no surplus holes or overhanging extra material to jab into any unprotected knees. It is seriously low also, only having 5 mm of rise. Total weight is 464 grams, which is a few more than the stock crown and the Easton stem I had been using up until now. If you are counting grams the added mass will be more then made up for when you saw off the extra steerer. The Prime stem is attached using the 888 bolt pattern, so if you were so inclined you have the option of installing a stem from a few other companies.





Installation was pretty straight forward, as you would expect. The tolerances were perfect with the crown sliding on smoothly like it should. Persist recommends using a torque wrench so if you don't have one it wouldn't hurt to head down to your local shop and get them to bolt it up. If it looked great in the box, then it looks even better on my bike. There is really nothing wrong with the stock crown but the Optimus looks far more ready for action.







I would not expect to have any issues with such a high quality piece of work and I never did. I am of average size but tend to crash a little harder than the average rider. Not once did I need to pull out the multitool to straighten anything after an off or especially hard landing. In fact, I brought the Persist crown with me on our annual trip to the RedBull site in Utah for two weeks. I spend more time in the air while in Utah then the rest of the year put together. If it was going to give me any gripes then that would have been the time. It didn't of course, it just did its job while looking great. I have noticed that some integrated stems have a bit of slop between the screws and the unthreaded side of the stem or crown. This is no doubt one of the culprits when you get up from a crash and find your bars twisted. There was no room for the titanium screws to move around in the Persist crown which means that everything is that much tighter. Unlike some bolt on stems on the market there was no sharp edges or overhanging material, something I really appreciated on those 'no pads' days.

I'll be the first to say it: £170.00 is a lot of money to be spending on a crown and stem. On the other hand, if you have a Fox 40 and can appreciate nice work then Persist may have what you need. Do you have a Boxxer instead of a 40? No need to feel left out as there will be a Boxxer unit available soon!

 Nice! I want a Fox 40 and one of those!

 Check my buysell! selling white ones with an integrated crown stem similar to this by burgtech

 I guess I'm not the only one who thinks integrated stems are stupid. What happens when you smoke a tree with your handlebar going Mach 2? I'd rather my bars just misalign than having bigger problems to deal with...
  • + 1
 I know. I throw my shit out of line on almost every run on my 888's. The only set I havent managed to throw off so much that I had to stop is on my shivers tall upper. People who try to cut weight just pay for it in the end. Im tired of having to hit the shit out of my bars to get em straight again. It costs me more time in the end. I went down at chdh and spend atleast 10 seconds kicking my bars until they were straight. Kinda shitty. Still made 17th being I was on the ground for more than 30 seconds. HA.

 The only thing that pisses me off about regular stems is when you take all the time to align and you are still off by that 1/32 of an inch that just irritates the crap out of you. I have the go ride top crown with built in stem, and it solves all those alignment problems. . .

 Everyone can yell a each other about how their fork is better and what not. The truth is all forks perform for the same purpose and it all depends on your preference or riding style. I have both a 888 and a 40 and I love both of them
  • + 0
 which takes more tech time. The whole point is to not have to baby your forks for them to work. Foxes take love. Zocchis can be left out in the rain / snow and still work just as good as they did before. Both are good... just one needs more attention to the other. After all bike parts are chicks are they?

 honestly t3h1337r i've scrolled down the comments and i've seen your name pop up like ten times. do you have no life or something? you keep arguing against everyone saying like oh 'looks dont matter' and cutting people up when they want to make their bike look good. you sound like you're one of those people who think they are so hardcore for not caring about style and making fun of the 'i care about looks trend'. you are actually a hypocrite cause trying to be the hardcore rebel is just as much of a trend as caring about style and looks. how about you just don't comment about stuff like that. honestly i really don't care if people want make their bike look good. i care about looks just as much as function.
  • + 0
 the funny thing is you had to comment back on it and not mind your own buisness. YOU yourself need a life my friend. The whole fact you took the time to type all that when really I could care less what you or anyone else has to say.

Its been raining here for 2 weeks straight... so computer it has been. Unlike you where you can go riding... I cant. Who has more of a life now?
  • + 0
 actually there's about three feet of snow here. the only thing i ride is skatepark pretty much every night. the only reason i commented was because i wanted to tell you what i thought. i've been stuck riding concrete for the past two months and i probably ride more than you.
  • + 0
 Lol why do you assume that you ride more? This isnt a pissing contest.
  • + 0
 does it make you go faster? No. does it make you a better jumper? No. does it make you have a smoother ride? No. if its $340.00 can. my answer is no I don't want one.

 The upper part looks a little small on the fork-side. I dunno if I´d trust it just that easily. But the lower part looks very nice, though it´s far too expensive for normal riders. Some people pay less for their whole fork.
Dear people at Persist: Please take a trip to britain, visit Hope/Orange/Burgtec/whathaveyou and ask them how to do it for an affordable and reasonable price. They know that stuff. Smile

 haha marzocchis can be left out in the rain and snow and and still work the same because they work like SHIT in the first place!!!!!!! HAHAHAHA

 the whole idea is a fork that dosent have to be rebuilt every year. You know the funny thing is if you rebuild a zocchi on the same schedule as a 40 the zocchi will still out perform any 40. May I also mention parts are more readily available.

 340 for a crown??? HA, or i'll just save a bit longer and go buy a 40 in the first place... some people just have WAAAAAAAAAAAY too much money

 dammm thats wayyy to much for a crown maybe if it was top and bottom

 damn thats a kickass crown. im riding the 40 and its probably the best fork made. idc what everyone says the 888's suck balls. all of them.

 nice man i got ta get me one of those

 the go ride combo is 50% cheaper and does the same thing I am sticking with that.
  • + 1
 I've got a Go-ride, I'd be willing to bet the weights are close to the same but the lines on this one are way nicer to look at. Given the choice, I'd go with this one.
  • + 3
 Heck the risse crown is good enough for me. With the kind of abuse i've thrown at my 888 risse crowns I'll swear by them. The only thing risse and go ride need to do is offer a 4130 steer tube for us that bend and break our aluminum ones.

And bullitxl seriously... way nicer to look at? Either you are full of estrogen or you are gay. Its a f*cking crown home boy... is it really that big of a deal how it looks. People today and their Ill buy it because it looks good rather than Ill buy it because it might make me a better rider.
50% more cost isnt worth the better looks.
  • + 2
 With the additional cost you could maybe put some money into some better tires, getting wheels trued, forks / rear shock tuned etc. Those will make you faster... not some snazzy cnc work. Save the cnc for your vehicle to drive you there. You wont get chicks by how your bike looks. You will get chicks by how your bike looks in your ride.

 "t3h1337r" you're so damn right!
Save money for repair on car and parts for bike, not for a good looking stem.

 haha the new 888s will crush the 40's in every way. Not only are they now lighter, they are stronger, stiffer, more reliable, cheaper, and may I mention sexier. Looks like fox is lagging yet again.

 what are u talking about??
marzocchi sucks now...the last time they made a good fork was 2003...now they take over a year to break in, and they feel horrible.
  • - 1
 Lol. Shows what you know.

Ive ridden their old and new forks. I havent taken any care of either my shivers or 888's. Same oil as the day thy came from the factory. Runs like new to me. And a year to break in? Thats better than a year to have to rebuild.

Fact is my 888's have taken 0 work and 0 repair since I got them. Try that with a 40.

PS how are the forks they made in 03 any better? Anything 03 and earlier are out dated. My 03 shivers dont have near the adjustment my 888's do. The shivers are dope but the 888's are still better.
  • + 0
 i had an 06 66, and i rode it every day, and it still hasnt been broken in, and the adjustments were really shitty. i had an 03 monster, and i still use that fork to compare everything else to cuz it was amazing.
  • + 0
 A monster isnt even in the same category as the 888 IMO. The weight alone makes it such.

You cant compare the adjustments on a 66 to that of a 888. Just because they share technology dosent mean they will work the same. Plus the whole fact a 66 is not a dual crown... no wonder they felt shitty. Single crows do that. (except totems. They have revolutionized single crowns.).

Might want to hack away on the 888s before you judge. I doubt you would go back.
