While most BOS sponsored riders opt for the French company's air shock in the rear, Andrew Neething has been testing a Stoy with a custom spring from Ti-Spings.
When you bleed brakes everyday you come up with a few hacks of your own to make the job easier and more accurate.
Lots of fork and shock rebuilds going down after the beatings doled out by Fort William, and due to the drastically different style of track here in Leogang.
RockShox's shock tech has his own homemade, portable service station that allows him to travel and operate in any race or testing environment.
Aussie Junior, Remy Morton and his dad have been touring around in this do-it-yourself van. Not a bad way for father and son to spend some quality time together.
Everything Remy needs to ride is crammed in out back.
While living quarters take up the whole front end. It's not glamorous, but in the end it's all you really need.
This is what being a privateer looks like these days at the WC level. While there are still the odd gypsy vans here and there, the majority of privateer are living the RV life here.
That's not say all privateers are on a super pro and dialed program...
Adam Brayton keeps what he needs and discharges the rest on this personalized chain guide.
Wouldn't we all like to know what's in here?
Take a close look at the top guys bikes and you'll see titanium bolts where they make sense. Again, it's all in the finishing details.
You know you've made it when you have a shoe drier in the pits.
Galfer is a force in the moto world and they make some pretty high end rotors and pads for MTB as well. This particular batch were hand delivered and custom etched for the Polygon UR Team. At the top level the devil is in the details.
Mud fenders were the first thing being mounted to bikes being taken back out of the box after Fort William. There may or may not also be a custom shorter carbon swing arm on this bike belonging to Tracey Hannah.
Aaron Gwin led Claudio on a chainless course preview today.
Claudio's bike all set up for his track preview run.
So, based on the schedule above, the bong ripping session is for only one minute?! Everyone knows that the UCI rules specifically state that bong rips are to be at least 10 minutes in duration.
Until you realise that you probably dont bleed brakes as much as whoevers doing that bleed and ruin your pads by getying fluid all on them...lol.
Then again, avids bleed procedure would make that pretty hard. No experience with saints.
@drummuy04: ahh. Just thinking of the old hope mono m4's i had at one time. Miss the master cylinder, accidently take bleed screw out half turn too far..overfill cylinder(pouring right from bottle) seemed like no matter what some fluid was going where I didnt want it.
Right? I've been running my Hope V2's for 5 years plus now. The only time I had to bleed them was once or twice when they were overdue for service. Sent them to Hope for a rebuild and haven't had to mess with them since. So.... Like two or three bleeds in 5 years. Hope's are the sh*t!!!!!
Lol. Thease guys just live the dream. Fresh bleed, new tires, fixing shox right at the base of the mountain. Plus, they geg it dor free. Talk about getting that new bike feel on the daily.
adjusting the rear shox, switching springs to the terrain for each course should be all you really need to do. taring it apart seems just a little bit too much unless you are moving shims around. what else would you be taking a rear shox apart for? I guess if ur around with not much to do but wait with a bit of anxoity before a race, i can see myself just reviewing every detail over and over.... hopes for life!
how can you get the spelling (brakes/breaks) right the 1st time then not the second?? Actually, 'breaks' is correct in my experience of Hope units... As you were.
@nfa2005: from a guy who does it all himself, it's really alot easier then people think...avid are a bit strenuous due to degas sing the brake fluid, but its still easy. There's a lot to learn, but it's all relative. Every fork(almost), has a service manual somewhere, follow it. Brakes, same deal. Derailleurs, tuning is all the same.
www.sheldonbrown.com, this guy's teaches all, alot is more in depth then you'd ever need.
Parktool has alot of instructional stuff on its website, as does pinkbike, and finally youtube can be helpfull...the odd time instructable has some good info...
It's just screws, nuts, bolts, brings, seals, lockrings, air, oil, brake fluid, grease and chain lubes.. alot of these don't really even have to be "bike specific". I repack my bearings with run of the mill all purpose grease, and some brakes allow the use of regular old dot 4 from crappy can....
PM if your really lost, never mind helping a rider avoid 35$ an hour shop fees. Plus when you're confident in what you're doing, you can go under table with other peoples bikes (friends, friends of friends and relatives etc..) downside is, you have to invest in a fair amount of tools, wich again don't need to be "bike specific" for the most part, they're are some though...
If you've ever bleed shimano brakes after a season you'll notice how it goes in a nice pink clear colour, and comes out black. Shimano recommends regular fluid changes.
I don't get that galfer rotor. Why are the rivets leading the disc? Why are they positioned in such a way that they wont really allow for heat expansion? Why are the surfaces that take the braking loads angled like that? The normal rivet style (as used by hope and most moto rotors) makes so much more sense in my eyes. Perhaps there is good logic behind galfers design, but I sure cant work it out.
Weirdly I just looked at some rotors galfer make for motorbikes and they all have a much more normal design. Only mtbs get these wierd rotors it seems. Wonder why??
The braking pressure rotates in and distributes the forces more evenly.
Or maybe the forces involved in mtb vs moto are so small, they can just design them to look pretty without worry about exceeding the forces required to fail...
There is a long contact area between the the two pieces behind the rivet, and the angle would have them driving tighter together as braking force is applied and distribute the force over the long contact area - the rivet is simply to keep them connected. If the rotor was run backwards it would probably fail spectacularly, and quickly as the two angled surfaces would be separating, and only the rivet, and thin backing of metal would be there to hold things together.
- I think.
yeah I see that. Just don't see any advantages over a more traditional design like Hopes. The rivet placement is odd in the Galfer rotor as it wont really allow for heat expansion unless the rivet is very loose. If the rivet is loose enough to allow for expansion then the angled surface is going to get very loose very quickly. Just seems not as good as the traditional design to me.
These are some great behind the scenes photos. The attention to detail in some of these bikes is amazing, granted that's probably where the high prices come from!
based on the Ohlins sticker at the bottom of Braytons fork, its likely and air spring. So I suspect one of those top cap screws hides an air valve. Or maybe both (1 pos. 1 neg). Or one is a bleed screw for internal unwanted pressure. very common in the moto world.
Its just a boxxer with a ohlins cartridge. They work with coil and air springs and no it doesn't have extra springs. you can already buy them for 40s they just aren't out yet for boxxers. you can check out feature here www.ohlins.com/product/stx22-for-fox40
I'm wondering if it's actually an Ohlins chassis with a boxxer sticker to help cover that up. From what I know the inner stanchions of the Rock Shox products are not held to tight enough tolerances for Ohlins to make a cartridge kit that they are happy with. The inner diameter of the Fox 40s are consistent enough.. that was at least the case last year, but who knows, maybe something has changed.
@nismo325: Except the top cap is visibly different than what they show on the website. Theres zero need and financial justification to change the layout of the top cap unless they've changed something internal that corresponds with the top cap.
@cthorpe: fox and boxxer run different size stanchions so they may have have had to adjust layout to work on both forks. If you look both forks still have two screws on top that look exactly the same. Also they aren't going to give the boxxer version different features than the fox version what would be the point off that? its just a cartridge replacement like fast and avalanche. This is all kinda old news.
When bleeding a brake, you'd usually remove the pads, push the pistons all the way back and then use a generic brake/piston stop. Once the bleed is done you have to pump the brakes to re-engage the pistons to come into contact with the rotor again. Guessing that using a rotor instead of the generic brake/piston stopper, saves a step and maybe even allows for a slightly more accurate amount of brake fluid into the system.
@adrock-whistler: yeah you'd definitely get more fluid in the system that way for less freeplay before bite point. basically the same as advancing the pads with the rotor out of the brake (as has been mentioned by the writers on pinkbike many a time) except with keeping a full reservoir.
Keep in mind if you bleed this way with worn pads, you'll rub with new ones until you bleed again. These guys probably throw new pads on for every bleed, but for me, I'd rather bleed with a known dimensional bleed spacer, like the bleed block.
You're also running a much higher risk of getting mineral oil or DOT fluid on the pads, which would negate bleeding the brakes in the first place. I'll stick with the regular bleed block but do a lever bleed when the rear brake is back on the bike.
Yes you have a greater risk of pad contamination, but if you where the kind of wrench to do that you wouldn't be working a WC pit. Less free play at the lever, more power and bite at the caliper.
yes. in-bath rip using a traffic cone bath bong
Brake fluid still needs to be changed regularly. It can absorb moisture from the air. It can loose it's ability to absorb heat. Etc

True. But water can still enter the system.
