BIKE CHECK:
Brendan Moon's
Bilt Eight
WORDS: R. Cunningham

| I felt that the bike rolled noticeably faster and had more grip, which allows for faster cornering and exit speeds. The wheels seemed to allow me to float over the top of holes and skim through rock sections that I was previously getting bogged down in using my 26 inch wheels. - Brendan Moon |
Brendan Moon, or "Moony," as he is known on the Australian DH circuit, is one of the better downhill racers on the island continent. The bike he rides, the Bilt Eight, caught our attention in the pits at the DH Nationals in Bright, as did the
recent video that featured Moony testing the aluminum chassis with 27.5-inch wheels. The Bilt Eight is the brainchild of founder Bill Dengate, a former DH racer who once imported boutique bikes into Australia and later decided to design and market his own brand. With long and low geometry, simple lines and a bullet-proof, linkage-driven single-pivot-swingarm suspension, the Bilt Eight has been earning a cult following among Aussie DH riders - including Bill's son Benjamin, a ranked Junior who posted a fifth place at the Nationals last weekend. We asked Dengate about the origins of the bike and about the motivations that led to the present design.
The CT-Link rear suspension is a basic, single-pivot swingarm
that hinges close to the top of a 38-tooth chairing to minimize chain
growth. Parallel "push links" drive the shock rocker and allow for
a straight seat tube. The Eight has no special adapter for 27.5-inch wheels. Both
sizes fit between the stays and it is up to the rider to tune the head
angle and BB height to suit. The Hans Dampf rear tire fits snug. Dengate says that quick-release through axles work loose, so
Bilt uses a 12-millimeter aluminum bolt. Simple and effective. Moony switched the stock lowers of his Fox RAD 40 fork to the
27.5 models to obtain the correct tire clearance and fork offset. Bill Dengate: Is the frame on the bike that Brendan Moon rode this weekend a stock Bilt Eight?Yes, Moony runs a stock off-the-shelf Bilt Eight frameset. It comes as a package with a Cane Creek Double Barrel shock and Angleset
Is the 650B option a conversion, or is it based upon the fact that the different wheel sizes will both fit the frame?Yes, When we developed the Eight, we did it with a view to running larger wheels and making it compatible with both wheel sizes (basically future proofing it!). The only real issue is bottom bracket height and we found most guys' actual setups put the Eight's bottom bracket at a very low, 13.1 inches ( 332mm) when running 26-inch wheels (we advertise 13.4" or 340mm). When you run the 650B hoops, it increases the bottom bracket height by approximately 12mm, which is still very low and puts the bottom bracket around 13.5 inches (344mm), which is still on the low side of things and keeps it riding like it should.
Are their plans for a dedicated 650B design?As the frame sits at the moment, we are pretty happy with it. We may tweak things a little for the next production run, but nothing massive. We will probably increase tire clearance a little, as there wasn't any 650B DH tires available when we were in the design phase three years ago. To be honest, I'm a bit lost with some of the banter being thrown around about "650B dedicated geometry." I mean, I've seen bikes with wheelbases that would cover two zip codes and all I can think is that it would make it ride like a boat and magnify the sensation of running larger wheels, which is something we've found our customers really don't want. Most want the chuck-ability of a 26-inch bike, with the benefit of larger wheels. We tried stretching it out, but found we lost a little of what makes the Eight such a fun ride. The frame also comes with a Cane Creek Angleset and three adjustment cups, so there is scope there to further dial your ride if you feel the need.
Describe the leverage rates of the CT-Link suspension.The leverage ratio is a fairly linear rate. Basically, it runs from about a 2.9 to 2.4:1 ratio. This gives it a nice bottomless feeling as the leverage ratio falls off, while still keeping small-bump compliance. There's no hard ramp-up but there is enough there when you want to mash on the pedals and sprint for the finish line. This, in conjunction with the main pivot location, means the bike pedals very well when you want it to go forward without jacking or squatting or doing any of that funky stuff.
What is the primary reason for the unusual linkage?Wow! I didn't think it was unusual, but we'll take that as a compliment. It's pretty normal stuff really, except we decided to go for a push link around the seat tube rather than design another interrupted seat tube design. The linkage is the brainchild of our designer, Christian Tucker, who developed a number of different linkage sets before we found the sweet spot and had the bike riding the way we wanted.
Will the Bilt Eight be available in Europe and North America?Sure, We will ship worldwide. We are currently also working with a number of agents in Europe and Asia, which should speed up the delivery process. We currently send via air freight, which is fast and we do our best to keep the cost reasonable. If you are in North America and interested in selling some frames, email me!
What motivated you to strike out on your own and start a bike brand?Besides my riding, I have imported different brands into Australia (Turner, Da Bomb, Keewee) and eventually I just decided that I should do my own thing.
Did you design the Bilt Eight from scratch? Where is the frame manufactured?The frames started out as a Taiwanese off-the-shelf design, you know, like the ones you see at the Taipei bike show. We thought it looked OK until it got here. We ended up pretty much redesigning the whole thing, and after three prototype versions and four linkages, we ended up with something that we were happy with. They are manufactured in Taiwan by a reputable factory and to date, we haven't had one breakage, which is something we are extremely proud of. Most of our team guys are still on frames which are now over 12 months old - and have now done two National series without a hitch. They are hammering them. Each frame is pulled down, checked and prepped before it leaves here, so it is ready to build out of the box. It isn't the lightest bike on the hill, but will easily build up sub-38 pounds with an affordable, real-world kit.
We understand that you also raced downhill. Yeah, I raced for years, reaching the dizzying heights of mid-pack in sport/veteran classes. Much more focus on having fun with the guys on weekends away, than really trying to hammer out great results! My son is currently racing on our bike as well and he has just snagged himself a fifth in juniors at the Aussie Nationals on it. At this time, Benjamin is a hopeful for selection on the Australian National team, which would be great.

ComponentsMoony rides a conservative component kit. His front tire was a Maxxis High Roller II and the rear, a Schwalbe Hans Dampf. Cockpit controls were a Shimano XTR shifter and Saint brake levers (Moto style) on a Renthal Fatbar, clamped by a direct-mount Twenty6 stem. No telling where the Cane Creek Angleset was adjusted to, but a look at the side shot of the Eight suggests that the head angle is raked as far as it can go. Odd combination, the Shimano Saint brake calipers clamp Hope Sawtooth rotors. The crank is Saint, but the chainring is an elliptical Rotor Q-Ring, and behind them, a Shimano XTR mech shifts a nine-speed cassette. Moony's plastic SPD pedals makes ya wonder why Shimano has not produced a decent DH pedal to compete with the Mallet.
Below the Twenty6 stem and high-rise Renthal Fatbar is a Cane Creek Angleset that is standard kit with every frame - including three different lower cups. Saint calipers gripping Hope floating Sawtooth rotors is an unusual sight. One of the oddities of DH is that, at present, over 75-percent of the leading pros ride Moto style (front brake on the right grip). A look at Moony's drivetrain suggests that he likes a quiet ride - minimum chain length and lots of rubber on the swingarm.If you want your own Eight, Bilt will sell you a frame, complete with a Cane Creek DB shock, a fresh bolt and axle kit, and a Cane Creek Angleset for $1999 plus shipping charges.

You mean 75% of pros have their bikes setup the RIGHT way
DUCKS>
The front brake SHOULD do most of the heavy braking but if you try to use it to control the bike in the corners you will crash.
i couldnt pair the front brake with the rear shifter pod.. id always think it was the rear brake.
Also, who makes that front fork? I couldn't tell.

It's not exactly the same, I know. Nicolai dropped this model because of its weight but I've no doubts that the system will rock. I've had a Nicolai Ufo_ds and it was brilliant, I've tried the Nicolai M-Prime and talk about plush and low center of gravity, so I'm sure this one should rock as hell. With this, I'm sure this new bike will most probably work very well being based on the Nicolai, it's the same way with the Norland Project (www.pinkbike.com/u/annimaxdh/blog/norlandcyclesstealth.html) and the Brooklyn Machine Works Racelink.
In the end, if you're going to do something new based in something old, than use the good examples, and that is what these guys are doing so we can enjoy good bikes .
A) new.
B) old.
C) different.
D) expensive.
if they rode it they might still bitch BUT I'd they happen to OWN one it's the best thing ever made.
E) if it's not 26'
75% of leading pros? That's simply because many of the fastest guys are from Commonwealth countries - South Africa, Australia, New Zealand, UK. Not sure how Stevie runs his brakes - Canada being an anomoly in their bikes are generally set up non-moto since they followed the good ol' USA (where 'moto' style is an informed choice, as commented above).
Whether or not these laws are known about these days or not is irrelevant, as the habit has been set. But when I was a kid the cops that came to my school even told us that it's against the law to sell a bike setup wrong. You can do whatever you like once it leaves the shop.
Almost everyone that craps on about being 'oh so moto' just ended up that way by default; it has nothing to do with you being cool or, more likely, otherwise.
So for control, it can be an advantage to be faster rather than having power from your dominant hand.
I ride left for front brake although I'm right handed and feel it's better for me.
I tried moto style in the past and it was ok too but I'm no motorbike rider and I play guitar, so even if I'm rigth handed, I usually use my left hand.
In the end I think it's just personnal preference, none of the two style is better than the other, just ride what works for you.

I am right handed and have FAR better fine motor control with my right hand. Writing with my left hand looks like the scribblings of a sleepy 5 yr old. I assume the same will be true of my braking control. Motor skills can definately be learned. The first time I tried left foot braking in my car I had very little control of power modulation, but with practice I have improved. My right foot is still far better even after extended periods of using ONLY my left foot.
All I could find is in French, hard to know technical vocabulary in English to find articles you can read, except if you read French, sorry...
But basically it was just a poor argument (but true) like saying "Moto style is better beacause it's Moto".
And of course like you said, if you usually don't use one hand or an other, it will feel less confortable than with you dominant hand.

Ironically our esteemed RC is mentioned in a different lawsuit (as the designer though he wasn't named as a defendant of the lawsuit) involving derby corp that had to do with a defectively manufactured rigid fork failure. The basic problem then was RC designed the fork to use a certain grade of tubing, the brand contracted out its manufacture and the factory in taiwan substituted in an inferior tubing and then made things worse by introducing a crack during the welding process which meant failure inevitable. The ultimate judgement totaled less than $400k which for 1997 and the type of injuries were quite reasonable.

This is not my video or vimeo so don't give me credit for this amazing work.
WTF? LOL
Has RC considered that a great deal of guys that ride pedal bikes also ride motor bikes?
And just how many vids have you seen that shows our fav DH'ers on motor bikes?
I'm willing to bet that motorcyclists have a greater tendency to DH and FR then XC, which would explain why the lycra crowd is always so
shocked that anyone would do such a thing.
Moony rode the 26 size for a while and decided to test the 650b, this is not a marketing line this is how he felt on the bike, he was open to ride the 26 if he wanted to, I don't believe there was any pressure to do so as the frame runs both. . He also has said that the larger wheel size might not suit every rider in other reviews. flowmountainbike.com/post-all/video-testing-a-650b-downhill-bike-with-bilt-and-brendan-moon
Sorry Bill but that rear end is going to suffer from SERIOUS brake jack/squat whatever you do with the main pivot location. You making mention that it doesn't does little but make me want to search the rest of the interview for other marketting bull. Shame, as if it rides anything like a mission 9 it ought to be a good little bike. Cut the marketting bull. People are growing tired of it.
On a side note that pivot location will lead to a bit of bob when pedalling as there will be no pedal "jack" to counterract the downward inertia of the riders bodyweight. Placing the pivot a little higher will improve pedalling alot but cause lots of pedal feedback over bumps. Your pivot location is indeed very good for a burly dh rig as there should be very little pedal feedback from the suspension, but unfortunately this goes hand in hand with poor power transfer to the ground. This is why I commented as claiming the bike will pedal well is a bit misleading as there are many other frames out there that will transfer power much more efficiently. I do not really care about power transfer so would probably really enjoy riding your frame. I just don't enjoy people trying to extract my money by telling me stuff about their products that isn't true.
Maybe you didn't quite deserve my comment as much as I thought previously, but there is a whole load of utter bull floating around in the MTB world right now, and instead of trying to filter it out for the consumer as they should, many mags and websites are joining in and parroting on the same lies in their articles. I am very sensitive to these things these days as the more they get spouted, the less good MTB becomes. I plan to be riding my whole life and don't wont to be forced into buying some shit piece of marketting crap next time I need a new bike. Your frame however will most likely be on my list next time I'm looking. As long as it still has 26" wheels by then. I like going round corners you see. Much like power transfer, I care very little about straight line rolling resistance.
I don't work or have any affiliation with bilt btw, although some of my comment might seem so
Bahahahahahahaaaaaa!!!!!!!!! OMFG!!!!!!!!!! ROFLMAO!!!!!!!!!!!!!!! Is there anything these salespeople won't say?!!!!!! Too f*ckin' funny!!!!
Now the sad part, some of you dumb as dog loaf retards actually believe him!!!!!!
Oh & that bike looks like a rip off of a Knolly craptraption.
We are absolutely happy for people to run whatever size wheels they like!
I'm guessing you ride 26 inch and haven't actually ridden 650b for DH?
Bill
complete and utter bollocks. marketing hype 101
if sheeple believe any of this toss, they are even more gullible than I thought they could be
unbelievable crap
