Press Release: Reynolds

The Reynolds gravity wheels have become somewhat of a gold standard in the industry and amongst athletes due to their nearly indestructible nature and race-winning performance. The collection’s universal praise was earned as much through numerous victories at the world’s highest stage as it was by single wheelsets competing and winning over the course of complete EWS and UCI DH seasons. The Reynolds engineering department, steadfastly dedicated to continuous innovation, felt there were opportunities to build even more performance into what was already hailed as the competitive standard. The fruit of their labor comes in the form of the new Reynolds 307 and 309 Gravity wheel collection that represents a whole new level of performance while maintaining the Reynolds calling card of durability.

In developing the new collection, working closely with the world’s strongest athletes in both DH and Enduro proved integral not only to identify areas where performance could be increased but also to test all iterations at the absolute highest level for approval and validation. Feedback from prestigious athletes at the pinnacle of sport such as Pivot Factory Racing, whose palmares in both DH and ENDURO speaks for itself, would prove integral to the overall design direction and development of the new wheels. While conventional mindsets were looking for stiffer wheels, the testing with Pivot Factory Racing highlighted that adding compliance to the wheelset actually increased tracking capabilities and control, translating to better handling and faster overall performance.

The groundbreaking revelation in performance through compliance resulted in a wildly different rim design when compared to previous iterations. The rim design of the new BL307/BL309 is visibly different, even to the naked eye, as it is markedly shallower and slightly wider. The new profile is 5.5mm shallower, going from 26mm in the previous version to a vastly shorter 20.5mm which aids in vertical compliance to the tune of nearly 40% in the IDM/Black Label version (30% in the TR version). The 30mm wide internal channel (37mm external) makes for a better tire interface and adds additional compliance through better overall tire performance. The new, low profile rim design is also slightly asymmetric which allows for more equal spoke tensions which result in an extremely robust and reliable wheel build.

A race-winning wheel is an efficient one and the Reynolds BL307/309 wheels ensure that rider input is translated into forward movement. The asymmetric nature of the rim profile ensures a better transfer of power. The Pro version of these wheelsets use the Reynolds designed, Industry Nine produced, proprietary Black Label Hydra hubs are fully CNC machined and offer an instantaneous .52 degree engagement for efficient and immediate power delivery. The Expert and TR level wheels transfer power precisely as well via Ringle Super Bubba X and Bubba hubs.

As important as added compliance, better handing and more efficient power transfer might be towards overall performance, they mean little if the wheel is not reliable. The caveat in the development of the new wheels was that no design element was sacred but both performance and reliability could only improve. The all new BL307/309 wheels represent the absolute fastest wheel solutions available for DH and Enduro but also lead the industry in terms of impact resistance and durability. Such reliability derives from the Reynolds IDM Matrix which is a combines the highest-quality carbon fibers, a unique resin with exceptional impact dispersing characteristics and meticulously studied layup and orientation of the two. The IDM matrix technologies allow Reynolds to develop wheels that stand alone in their strength to weight ratio…making for wheels that not only are extremely reliable but represent no compromise in terms of weight.

Available in both 29 and 27.5” versions and also separate models for Enduro or DH competition. The enduro wheels receive a 28 hole build in an effort to further increase the compliance and lower weight. The 28 hole build tends to be a bit more forgiving and necessary for the longer descents and lighter as the enduro athlete must overcome the rigors of long climbs as well. The DH version on the other hand gets a 32 hole build as the downhill athlete requires a slightly stiffer, more precise performance, with less emphasis on overall weight.

Such a complete package was a difficult feat to achieve and while the role of the athlete feedback was integral to the development of these wheels, their success and approval was absolutely vital in determining validation of the final product. The Pivot Factory Racing team certainly tested yet also competed on this new rim for an entire season of UCI DH World Cup racing and the results were amazing. Overall team success, Bernard Kerr’s best season of his career and a World Champion jersey for Jenna Hastings would serve as all the proof necessary that the new Reynolds gravity wheels were ready for launch.

The previous version represented the most durable DH and Enduro wheels available, capable not only of surviving entire seasons underneath world-class riders at the highest level in the most extreme racing circumstances…but winning also and were considered game changers as a result. Using this industry-leading durability and performance as a foundation upon which to build more compliance, better handling and, consequentially, more speed is redefining what the pinnacle of competitive gravity wheels should be. Reynolds BL307/309 gravity wheels: industry leaders for durability, compliance and control…and as a result, speed.

 So many words.. So. So. Many. Words. And not a single one about warranty

 Its lifetime for anything riding related.

 @Daaaaaaaan: only for manufacturing defects. Text from their site below. Contrast that with the text of Santa Cruz's Reserve Wheel warranty below that.

Reynolds:

To the original owner, Hayes Bicycle Group (HBG) warrants Reynolds carbon rims against manufacturing defects with a limited lifetime warranty. This limited lifetime warranty covers the Reynolds branded carbon rim if damage occurs while riding in normal and intended use. Within the first 2 years of purchase, spokes, nipples, labor, and return shipping will be included when a rebuild is required and when received at the factory or authorized distributor location with a valid proof of purchase, freight prepaid. All other warranty claims not included in this statement are void. This includes assembly costs (for instance by the dealer), which shall not be covered by HBG. After 2 years consumables, spokes, nipples, labor, and return shipping are excluded. In the event of a non-warranty or non-riding incident, the original owner may qualify to receive crash replacement pricing.

Santa Cruz:

We'll repair or replace at our option any Reserve rim that is damaged or destroyed by riding. The warranty will be in effect for the lifetime of the rim and is available only to the original owner.

 @djjohnr: 'at our option' leaves infinite leeway in their choice to actually honor a claim. 'only to the original owner' pretty much invalidates ''lifetime of the rim' and should not exist in the same warranty disclaimer, imo. Just sayin.

 I'm assuming based on price these are carbon, but does it say anywhere in whether or not they are?
  • 13 0
 Yes, the phrase “highest quality carbon fibers” appears in the middle there.

I’m personally more curious about the i9 produced, but “proprietary” black label hydra hub is all about.

 You mean "MR5 IDM TSS" isn't completely self explanatory?

 Building your own wheels for enduro is pretty much the way to go. Street price is roughly the same, and can build 32/32 spoke sets that handle hard riding much better. More spokes is significantly better in a mishap where spikes are lost as well

 good to see brands talking about vertical compliance with carbon wheels, many companies carbon wheels are just to stiff and lead to terrible handling and flats

 Which wheel did Bernard kerr destroy at hardline? He tested that to its limit!

 I don't remember about their DH team but I think I remember Reynolds wheels lasting an entire EWS season. But I agree, its hard mentally to not think of that crazy wheel explosion and resulting crash even when I know they are strong wheels

 110 feet gap to flat, doubt lots of rims would survive that kind of impact!

 @IsaacWislon82: if you look closely the ews wheelsets were j bend 32h like the dh wheels, and never 28 spoke straight pull offered to the public.
  • 5 0
 Why has 28H straight pull become so "popular" anyway?
  • 5 0
 @boozed: straight pull spokes are technically stronger, but it takes a ton of skill to build them properly. if they aren't tensioned properly, you get float, meaning on compression the spoke head will actually lift momentarily out of its seat, before slamming back when the wheel unloads. this leads to rapid failure of the spoke.

28H vs 32 is simply a weight/cost saving measure. less spokes, less nipples, less drilling, less build time. 28 is fine for an enduro build if you are under 150lbs, past that, if you are a charger, always go 32 on the rear....28 on the front if you wish.

 @Mtbdialed: I'm not convinced a 28h straight pull hub is less work that a j bend hub.
@boozed: idk maybe people think straight pull is cool and 32h straight pull are more difficult to make and (therefore?) less common than 28h straight pull

 If I remember correctly, BK said that he had probably cracked the rim before he hit that jump.

 @englertracing: I thought straight pull was cool until I tried to source replacement spokes...

@Mtbdialed: So from that I assume truing a slightly bent rim is a PITA with straight pull?

 @boozed: well working with round straight pull is annoying, but bladed is nice, you can buy or make a bladed spoke holder
  • 2 0
 @englertracing: they make a pretty effective tool for holding rount straight pull. $20 or something. I find it easier than than bladed really....

 What does the rim alone weigh?

 Good to see they no longer use their own hubs because those were utter crap. Loved the rims though. Always straight as an arrow, never needed truing.

 This top model has quite high hub engagement. Isn't that supposed to lead to significant kick-back on a full suss bike?
  • 2 0
 Think about it like this...
When you're pedaling uphill, and your rear suspension compresses, do you notice it and say, "wow, my pedals are getting kicked back" Most likely, you don't.

It's similar going downhill; barely perceptible, and assuming you can keep your feet in position, kickback translates into torque at the rear wheel that will propel you forward.

My experience is pedal kickback is mostly marketing hype.

also.. someone on one of the big MTB websites has done the math on this to determine how far rearward the axle path would need to go to get a given amount of kickback. It's a thing, but it's probably not what's holding you back from being a better rider.
