talk about proprietary spokes...we ordered a single, black Xyclone spoke for a customer...took 10 business days for it to come in.

Nice that you can figur eout the flex of a wheelset simply by a picture.

I have the Xyclone Disc wheels on my XC bike, and I cannot say a bad thing about them. They are more then stiff enough for me (210 lbs) and they have been, to be quite honest, dissapointingly good. I say dissapointingly, cause they make for a boring review as I had nothing toc omplain about, other then cost and replacement parts cost.

i've got a buddy that's been running these for a couple years now. they've been bombproof so far - not a wiggle out of them. they use doubletrack rims, so it's not entirely unsurprising. they do look cool:

i did give him **** for not aligning the michelin logo on the front tire.............................................................^^ the shame!^^

Im about 99% sure he meant that the spokes are 'flexy' in comparison to a regular metal spoke, not that the wheels are not good.

I'd certainly be willing to try a set. They seem like a pretty solid product. But they should definitely come with replacement spokes.

would their fiber spokes not stretch like traditional metal ones? would this eliminate the need to retension after the wheel is built?

The Spingergy road wheels that have a very similar design are really good. My buddy is pretty porky and has put about 5k on the road wheels and they're still really straight.

Buy a few extra spokes from day one, and those could be some killer wheels. Still too expensive though.

I had the XC versions and never noticed any extra flex...they road really nice. The road versions ride nice, but i did notice some flexing in the read wheel under full power in springs.

I don't entirely understand the dynamics of a bicycle wheel but I did read some book that was in the university library that had lots of neat equations and freebody diagrams. I understood that when loaded the spokes are not actually in tension but compression, it's been a long time so don't quote me on that. A flexible spoke theoretically shouldn't work as well as a ridgid spoke, it seems that the reviews attetst to the contrary.

Bike wheels work entirely in tension. Under compression the spoke simply pushes the nipple away from the rim transfering no force and often poking a hole in your tube.

Something like an old wagon wheel probably worked more in compression as the joints probably couldn't hold tension as the assembly was held in place by a metal ring compressing everything together.

it's seems counter intuitive, but theory / modelling indicates that the hub is supported by the lower spokes under compression, rather than the upper spokes under tension. here's some fea analysis for the geeks:

I didn't read it but I would guess the folks doing the analysis didn't take into consideration that the standard spoke mounting in a wheel does not allow compression. Here is a little test for everyone. Take a rim and mount a single spoke with a nipple. Now push on it and get back to us on what happens.

Jenson claims the weight at 2540g and spinergy claims the weight at 2150, anyone know for sure how much they weigh?

And they really aren't all that expensive. 823's on hadley's with DT spokes would weigh more and cost about the same amount.

i've had a set of the XC discs for a few years now. they've taken a serious pounding and haven't been anything less than great and light.

caveat: i'm 155lbs soaking wet.

The only way I can think of a bicycle wheel so that it makes sense is to consider a single spoke, if you stand it on end and try to balance a cinder block on it you'll most likely buckle the spoke and smash your fingers. Now you anchor one end of the spoke to a strip of metal and the other end to the cinder block and tension the spoke while maintaining a fixxed distance between the strip of metal and the cinder block with some mystical force. Say the spoke has 20 lbs of tension, that means that it will take more than 20 lbs of force to buckle the spoke, or make it push through the strip of metal it's anchored to. If your cinderblock weighs less than 20 lbs it won't buckle the spoke and it will not push through the rim because you are not overcomming the tension in the spoke, but you are compressing it relative to its starting state.

I know that doesn't make much sense either and I'm not sure it's entirely a valid explanation, but it's the only way I have been able to pretend to understand how a spoke can push up on the hub.

it has to work on tension... no way compression... like the other dude said, look how spoke nipples just sit in rims...

besides, force comes down from your body weight, into pedals/handlebars, through frame, into axles, pulling down on the spokes, which are dangling from the rim above...

looking at the finite element analysis of the loaded wheel (in the link), the bottom spoke contributes 15x more lift than the top spoke - ie, the spokes under the hub provide all the support. hard to wrap your head around (because a spoke/nipple interface with no tension offers no resistance to pushing out), but in the context of a tensioned wheel, the compressive forces from the hub never exceed the tension of the individual spokes, so the lessening of the tension (negative tension = compression) of the bottom spokes is what provides the resistance to the forces imparted from the hub (in my mind, anyways - we need some brainier folks to step in here).

Another classic RM E-engineer moment. :)

The wheels work, end of story. Of course, the spokes are far easier to damage (rocks, dropped chain) then standard spokes, but they're also ridiculously light. Spinergy uses custom rims that are slightly beefed up at the inside to withstand the highter tension of the spokes. They also use a Hadley freehub, with your choice of contact points.

The only thing that sucks for me, is that they don't offer a Lawwill version so I could stick them on my Rotec. ;)

the aerodynamic profile of spokes has been modelled (mostly for road bike applications) and as you'd expect, thin spokes rule in that department. thick spokes create a whiffle ball effect.

Stupid question but since they use Hadley hubs wouldn't it be feasible to use the Hadley adapters say for instance if I didn't want the 135 qr rear, I could change them out with 12 mm t/a adapters and use them on my DHR?

My bro in law reps these wheels and he didn't know since he on the road side. I gunna try and weasel a set for my roadie bike to try.

small review:

Spinergy Fall Line (FR) Wheel Set:

The Product

Spinergy manufactures their own wheel sets and claim their FR product line is "Tough, Indestructible and built for abuse". Built using custom CNC machined parts and their own patented PBO Fiber Spoke Technology; these rims are light and have a custom look. The customer can select rim and spoke colors to match their mountain bike. For the complete OEM specification, please visit this direct link to Spinergy FR product line.




The Test

We at Dieselbikes plan on punishing these rims riding them on some of the toughest trails local to the Boston area. Whether they survive our 90+ day challenge, you will know below in our Final Verdict Statement. Out of the box, the rims are surprisingly light but stiff. The rear hub is solid and has a sounds/feel like it's a Hadley. In either case, looks are great but performance and durability is what we are looking for. We began our initial test at Bruce and Tom's going easy just to get a feel of the wheel set on the trails. After hitting a few small drops and blasted through technical single track with complete control, the rim's performance surprised us with minimal flex even through a few rock gardens.

Again this is just the beginning and we plan on switching riders and bikes with these rims to give you an accurate report.

We will post further information about our testing as we take these rims to Lynn Woods, Nam and Highland Mountain. If you have any questions and comments, please feel free to drop us an e-mail.




The Final Verdict

Well here is the final verdict... the rims held up! I must say we at Dieselbikes are surprised these rims did not fail during our testing. We took them to Lynn Woods, Bruce & Tom's and Vietnam. We hit drops to FLAT, some with transitions and rode the rear wheel with a flat tire down some of the nastiest trails Lynn has to offer. Throughout all that, the rims survived.

Among the normal scratches due to rocks and a few crashes we lost a little tension with only one spoke on the rear wheel. Aside from that, both wheels stayed true with no flat spots and or additional wheel flex.

Both hubs are Spinergy products and we have nothing bad to report about them. I have had freeride hubs in the past that began to loose up and/or bind on the axle after a few big hucks. I can only compare the Spinergy hubs to Hadley's or Chris King hubs. Smooth action, little flex and quality machined components with little to no play.

We had many riders comment on the looks of these rims. 9 out of 10 said the wheels look sick and the white spokes were sexy. Another comment was that the spokes were so thick yet the wheels were light. The reason for this is because the spokes are fiber (like plastic) and not metal (steel). When you go to feel the spoke tension, you may think at first they are loose, but as you begin to feel the other spokes, you realize this is by design. The spokes were one of our biggest concerns. We really thought they would flex so much, their performance would be comprised. But they did not... they felt just like all steel spoke rims and were not light riders!



We love these rims, but do have one aspect we disliked. Everything related to performance, durability and quality parts can be said about other quality rims. With this in mind, the most frequently asked question regarding these rims were; "How Much Do They Cost?" Compared to building a wheel set consisting of Hadley's and Sun Mag30 Rims with steel spokes, you will pay more for the Spinergy set. But if you're looking for a light weight, strong, custom looking (spokes come in many colors to match your bike) wheel set, Spinergy Fall Line Wheels are the way to go.

We understand why these rims cost a pretty penny, but light weight combined with strength comes at a premium price. In addition, this wheel set is a fairly new product with new technology (PBO Fiber Spokes) on the market providing the rider with an array of colors to choose from to create that one of a kind look on your bike.

Regardless of these statements and or opinions above, the Spinergy Fall Line Wheel Set did the job they were designed for and that is the bottom line!

That's not exactly light for a DH wheelset, my Hopes on 721s are 1.9kg and cost around half that of the spinergy's. Based on looks though, i'd run them anyday, but in the real world i'd rather save the money. And the weight.
