RockShox Turn Coat Review

Oct 6, 2010
by Mitch Chubey  
For dirt jump and slope style riders there has always been the issue of figuring out how to route the front brake line. You could run a really long front break line; I have done that before, and have a complete mess of cables. The usual alternatives are to use a BMX over sized star nut or modify a regular one and route it through a narrow hole and have the line stick straight up out of the steer. RockShox has come out with a solution, enter the Turn Coat.

These other options are not that bad if you are running a mechanical up front brake as the lines are simple to route and relatively cheap to replace. With today’s bikes and brakes very few people run mechanical brakes, nearly everyone runs hydraulic. With the hydraulic you have to cut, remove the line end crimp and re-bleed the system every time you need to get your fork off or change something in the cockpit, which is time consuming and can add up in costs. With this system you still have to detach the line at the lever, but you do not have to cut the crimp on the end to have it fit through the narrow hole, saving time and money. Also after one too many cuts the brake line may need to be replaced, as it is no longer the desired length. If done carefully and correctly the line can be detached and reconnected without having to be bled.

The device itself is simple. Consisting of an aluminum tube, 4 bolts (2 long, 2 short), and 2 caps. It tightens the headset by pulling up on the bottom of the steer and pulls down like a normal star nut cap on the top of the steer, compressing everything. For those who remember the headlock system it is very similar or how Chris King tensions their 1.5" headsets.

I originally ran this system as just a headset retention unit on a new bike with a new fork and headset. Most of the time a new bike's headset will become lose as everything breaks in. I never had to touch or adjust anything after my initial set up. During the course of a month I rode everything on my 6-inch travel Morpheus Loki. Downhill, jumps, drops; even 50/50 cased a few things. Never had my head set slip. Craftsmanship is top notch and everything lines up and threads together beautifully.

The system itself is simple and clean. Without the break line routed in a standard fashion, I've had several people ask me what it was hanging out the bottom of the steer tube.



RockShox Turn Coat Details:

-Two caps and a rod eliminate the star nut and create a smooth interface for the front brake cable to run through.
-Bar spin and tail whip friendly
-Available for 1 1/8", 1 1/2" and Tapered Headtube set ups
-Availability: August 1, 2010
-$30 USD msrp



At just over double weight, 68 grams for both caps, center rod, and bolts (one short, one long) of a standard star nut, bolt and cap, (29 grams), and nearly the same as an oversized star nut, bolt and cap at 59 grams.

Installation can either be one of two ways; easy and not quite as easy. If you are installing it on a new fork, you are golden, as it will easily mount. The system will not work with a star nut pre-installed in the steer. I installed the Turn Coat on just that style - Star nut already in and it can be a pain to remove the star nut. With some forks the star nut can simply be pushed down and out through the bottom of the steer, which is not a huge head ache. With me this was not the case. I had to remove the star nut out the top as my steer tapers on the inside and is far too narrow at the bottom and the star nut would become lodged. The easiest solution I found is to drill the center threads out until the middle has been removed leaving you with the two round stars. Tap one side of the first star with a punch and hammer, turning it on its side. Once on its side it can be easily extracted with pliers. Repeat for the second.


The installation of the actual device is simple; much less complicated than installing a new star nut. Have your fork in the frame and have all your head set parts and spacers set the way you like. Once installed it will be difficult to remove the spacers and change stack heights as the front brake line will be routed through them. Pre-install the bottom bolt to the center rod, and place it up the lower steer. Depending on your steer tube length you will have to figure out either to use the long, short or combination of the short/long bolts (both included) to secure it in place.


The system worked as intended, looks clean, and is simple to use. There is not much you can knock on it. You can always knock the weigh as everyone wants parts to weigh less, but RockShox has done a great job with this product and it’s a must for any slope style or dirt jump bike.

 cool concept, but your other cables still have to be long so its kind of a pyrrhic victory

 nice use of the word pyrrhic on pinkbike!

 awesome indeed

 easy realy realy easy way to remove a star nut instead of pushing all the way down (and scraping marks down the steerer tube Frown )
drill the rivet lip off the top with a big drill bit
with a punch (allen key, screw driver) knock the nut down a bit aboot 1/4 inch
push the top star sideways an pull it out with needle nose pliers
do the same to the bottom star
job done in about 3mins

 and is the BMX star nut - the same idea ?http://www.chillengrillen.ru/webscript/published/publicdata/CHILLENGWEBASS/attachments/SC/products_pictures/fsa_bmx_starnut.jpg ???
seems that anyway the hydraulic line must be made inside the steerer tube of fork?

 Excellent write up and review. I'm gonna get this to replace my Gusset boat anchor "headlock" system on my Glory. Of course I'm not doing barspins with my 40 but I HATE the star nut. What ever happened to Azonic's headlock?
  • + 1
 Azonics headlock is still alive and kicking. I grabbed one for my dh bike a lil while back and it still pwnz imo. No slop whatsoever, and I tortured that bike at the local bike park.

 I have the gusset headlock. I just drilled a hole right next to the bolt on the top cap. job done.

 FSA has already done this with just a top cap its just rock shox gets all hyped up. Your gonna have to disconnect the cable anyway no matter what system you use.

 Sorry if this is a stupid question, but isn't this product kind of pointless on a setup that also uses a rear brake and derailleur? If you were running single speed, front brake only, then you'd have a really clean setup for barspins, etc. But if you've already got a mess of cables for rear brakes and derailleur, then why go to through all the pain of installing, and living with, this system? As you can probably guess, I'm not a dj'er, so I'm really just curious here.
  • + 3
 the rear brake and derailleur cables can go around the headset/head tube but the front brake cable cant
  • + 0
 Why not?
  • + 3
 because it would need to wind the same way as the rear, and since coming from the opposite side, you would need to bend the cable way back and around, which in turn would put a ton of stress at the hose mount point on the lever. It just takes a cable out of the equation. The less shit in the tangle the better. Now, you can just man up and run mechanical's front and rear and just run a proper gyro. Heck they even make a gyro for hydros. If your tailwhipping that much you would probably already have one tho.
  • + 3
 Or, just attack your existing cap with a Dremel and cut the slot for the brake line. Job done.

 Yeah, this is a solution to a problem that never existed. How many people actually bars and whip their fully's? Most of them will probably run this for poser points
  • + 3
 actually lots of people bar spin. Not that hard dude. Now whips are diff. A good buddy of mine is a tailwhip whore, but then again he came from a pretty solid street bmx background. Ever see what the bmxers are doing these days? There are tons of em that are crazy. And many of em are coming to mtb thx to sites like pinkbike and ridemonkey.

 yeh and so what do u think a slopestyle bike is..??... somehow i think its a 'fully'.. so yep i think people do b-spin & tail wip them.
  • + 1
 I know barspins, trust me. Still, most people won't do barspins while hauling the mail down some freeride trail. People who want to do barspins and tailwhips will pick a rear brake only hardtail.. How many people have big ass slopestyle courses to ride? No one, except whistler people.
  • + 3
 Nice being a complete know it all combee. I'm glad someone on pink bike knows exactly what everyone wants on pink bike. Look, to keep it simple, rock shox wouldn't have put the time into going into production on something if it wouldn't sell or be used.

Point is, many people are breaking away from hard tails. With bikes like the Blackmkt coming out etc it's WAY more common to see fully's than hard tails now at many places.

Also, what the hell does slopestyle have to do with bar spins? lol. You do realize that "slopestyle" bikes are heavily ridden as DJ & 4x bikes, + free ride bikes. You think that just because something has a name "slopestyle" bike that means it HAS to be ridden ONLY on slopestyle.

Yet again, epic failure for know-it-all pinkbike users.


Its ok tho, I was just as ignorant when I was 18...

O and btw, if you think only whistler has a slopestyle course, your missing the hundreds of ski resorts world wide that have similar.

 You are missing my point, and you don't need to call me all sorts of names. You are the know it all, and your last post is just as worthless as this one is.

 Care to highlight where I called you names?

Care to highlight where I put you down?

You do realize the second to last 2 comments were directed at pinkbike as a whole?

Know it all... def not. But I have seen the bike world for longer than you have been alive... and that is enough to get a general idea about how things work, and why people market the things the do.

 why on your triples? going to be doing barspins and t.whips with DH forks???

 Dual crown forks RaleighVoid! There are only 2 crowns on DH forks.

 Or dont run a front brake. whats the point if all your doing is riding slopestyle is there any need for two brakes?

 Triple Clamp or Dual Crown, same thing..."triple crown" is a misnomer.
  • + 2
 That comes from motorcyle lingo. "Triple Tree" is what you call either of the two crowns. Also sometimes called "triple clamp", because of the three clamping areas (steerer, both legs). Never "Triple Crown" though. He's just a little confused Wink

 Camom!
No 1.5?
I got a new brake set, and the front hose is too short! It keeps me from x-upping, but my steerer is 1.5...
And x-up is one if the few tricks I know how to do "/

1 1/2 = 1.5

 Why not run hydro gyros? When you take it apart and let go of a cable some fluid is gonna come out meaning bleeding it. You will need to rebleed it unless you pretty much have your shop organised as good as NASA
  • + 1
 Because a 30USD top cap system is peanuts compared to a gyro, and a lot more reliable too.
  • + 3
 Gyro is intended for the rear brake, not the front.

 If only they could make wireless brakes.... maybe in 10 years i hope
  • + 2
 You could quite easily, but it wouldn't have the same feel or responsiveness and would probably weigh quite a bit more, not to mention the total faff when something went wrong and the fact that you'd need a PHD in computing electronics as opposed to your handy 8mm spanner. I sure as hell wouldn't want my brakes to run out of battery halfway down ft william either Razz

 How does it handle fork compression? Does it just bend your line between the lowers and the bottom of the steerer? Or does the line suck back into the head tube? Because with a DJ fork that wouldn't be a huge deal, but I could see that wrecking a line after a while on a DH fork.
  • + 0
 A couple Zap straps will could handle that problem...^^
  • + 4
 this concept is to keep the front brake hose from tangling during barspins/tailwhips, which doesn't happen on bikes with 2 crown forks.
there would be no point to do this on a dh bike.

 because the hole is smaller and you need to cut the cable and re crimp it, as it said in the article.

 do you guys think the wheel would hit the bottom cap when you bottom out or is it not even close?

 Doesn't defeat the point of having to re-bleed a brake or what not, but it make it clean and fresh. I like it.

 if your carefull, you wont have too rebleed the brake..

 cool unique idea im down
  • + 1
 Is it thought? Isn't it just a headlock with a couple of wholes in it much like many other companies already make. The only difference i can see is the angle the cables go in and out. Neat but nothing new. Unless I'm missing something.
  • + 1
 the caps allow the cables to run in at an angle.

IMO like you said, going to the hardware store and getting a rubber grommet and drilling hole makes more sense, but this is a do no work and bolt on ordeal. Whatev, this will in the end help push people still running star nuts to switch to a headloc system. Most never venture to em because of the cost (30ish+) all the way to laziness. Maybe these will increase Answer's sales for theirs once people realize the answer is better in every way. (haha no pun intended)
