https://www.bikeradar.com/news/add-weight-go-faster-orange-bucks-the-li… WHATS OLD IS NEW AGAIN. Chris Porter has been not-so-secretly adding weights to world cup DH bikes since the early 2010s, apparently. https://m.youtube.com/watch?v=myFJTO8mdtw Then there's this from nearly a decade ago, TLDR Stott and Porter find that weights make average Joe's faster, but not his hand selected Pro riders (at least for this track)

I would also add, after spending most of my last rides thinking specifically about my tires feel, subtelties in conditions, rider's energy and mindset can change how a tire feels. For example, using the gen 1 Schwalbe Albert Gravity 2.5 US front/rear, mostly dry rides. Early in the season, not in the best shape, I was cautious but gaining confidence in the tires. I settled on the best pressure after 5-6 rides and just enjoyed them afterwards. Then I reached one ride where I was tired and the tires seemed skittish and less predictable. The ride after, they felt great...

I think it was mentioned a few years ago in a Pinion equipped bike review on Pinkbike. That's all I remember but this was specifically mentioned. Also this was in the days of gripshift only, before they made the electronic shifting option. @TheKaiser mentioned the same thing. As I remember it (or as I expect to be) their EOL testing servo motor is probably in the range of Nm, which you can't package in the smartshift mechanism. If I remember correctly there's an allen interface in the middle, maybe it would be possible to implement something like a suicide shifter...

You’re not the first to assert Leaf is winning in spite of the gearbox… instead of wondering if the benefits to unsprung mass might outweigh the loss of efficiency. Is it that hard to believe Lief might prefer the Vanth? Last I heard he demoed the bike before signing with Priority. They didn’t hold a gun to his head and make him ride the bike… it’s very possible he could’ve found another sponsor if he wanted… Let’s not forget Enduro is timed only on the downhill. And there’s clearly an unquantifiable benefit to having weight under the BB…as demonstrated by...

Yamaha actually bought Brose pretty much a year ago today; announced in March but completed on August 1; https://www.bicycleretailer.com/industry-news/2025/03/31/yamaha-agrees-…

Giant Syncdrive motors are not produced in-house. The center drive motors are rebadged Yamaha units and the hub-drive likely bafang produced . I would describe the product development as “semi-custom” with unique user interface, software and tuning. Having them branded as a Giant product has advantages for the consumer as they become the source for tech and warranty support and distinguishes the product from other companies offerings. This is similar to what Specialized has done with Brose and Mahle made products.

So, I actually fill out those customer surveys that SRAM sends out after you register products. A few weeks ago, I got one related to ebikes. After I filled it out, they reached out (presumably also to other people) to see if I'd do a research interview. I said yes in hopes to read between the lines on what stuff they're considering. Based on the questions they asked, I'd say they're considering various motor options. Everything seems to be on the table from conventional to eCVT. Lots of questions regarding weight, range, power, durability, and aesthetics. Pure speculation on my...

A 170 with burly everything and a 120 or 130mm true trail bike with medium-weight everything. If I can have one more, it's a dirt jumper, and if I get four I'm adding a DH bike. But medium is as light as I can go. I can't have light things because I break them.

It's physics. The braking torque applied increases linearly with the radius of the brake disc. Torque = Force × radius Ignoring other variables (like brake setup, applied force on the lever, same disc design, equally bed in brake pads and discs), increasing the brake disc diameter from 200 mm to 220 mm corresponds to a 10% increase in braking torque. This, in fact, feels for the user like "power is more easily accessible" and "you don't need to squeeze the levers as much". It's actually 10% less squeezing 😄 Then there are other benefits like a generally cooler disc and...

If someone in here wants to go down a whole new dimension of rabbit hole regarding power optimizazion and heat management through "rotor and pad optimization" I recommend this thread in a german emtb forum. Tirolbiker63 has gone to absolutely incredible lengths to compile what is probably the most comprehensive database of just about every brake disc and pad combination. Hats off to him! Just check all the links in his signature of his posts and use a translator. Here's an example of a test with 8 different discs in combination with "Sinter green" pads. https://www.emtb-news.de/forum/threads/bremsscheiben-design-vs-funktion… This thread is pure...

"Wider casing overlap under the tread" to me sounds like a less supple tread area. Isn't this also what Schwalbe did with the updated radial gravity casing in order to dial back some of the lack of support? I don't think its as easy as having 2 zones you can independently control that don't influence eachother much. My takeaway from radials is that there is no escaping the support/suppleness tradeoff

Idk whats going on in this forum lately. Amaury: I'm using radials. Schwalbe: our riders are all using radials. Us: no one's using radials. My personal experience, riding them in every condition imaginable, including snow: the biggest improvement in mountain bike technology since we figured out 64 degree HTA could apply to non DH bikes.

Is it just me or do DH casing Conti Kryptotals last 5x longer than Maxxis in the bike park? I'm currently on 20+ park days and these tires still have life in them. I don't think I'll ever buy another Maxxis tire.

Oh look here's ballz criticising a penis joke Sorry guys I couldn't help it.

If you Ugga Dugga....video it.

Its a shame UST never really took off. Sealant-less and tapeless rims would have solved a lot of the last decade's tyre related problems for me and many friends.

The M2S is a little bit better than a Bosch on virtually every aspect: weight, size, noise, efficiency, software, overall package (screen, controllers, lights), price of the bikes. But much more importantly, just look at the bikes, take any Bosch bike like the commencal, crestline, orbea, then compare their Avinox equivalent, they are just so much better looking. On top of that, a lot of brands have released sub-5k ebikes with the M2, some are even carbon. There is also the fact that they are releasing things much much faster than the other brands. This is coming from a happy...

Remember, there are alot of people who are what I've heard referred to as "Speadsheet Shoppers".. And with them, bigger is better. More watts, more better.. Bigger battery, better.. Avinox has done a good job at delivering more without a huge weight penalty. And from what I've heard, the new motor has done a good job addressing issues with the first motor. Refer to the podcast with Jeff and Robot. They are a tech company addressing things the way a tech company does. But, with all that said, I'm really interested in the rumors of a full power TQ motor...

Currently there is a material difference in traction control due to the number of magnets in the wheel sensor. Avinox also leads with 3rd party integration such as heart rate controlled assist and the whole system is cleaner in general with wireless remotes and a really solid touch screen display.
