I thought so! Dave said you'd be at this round. Sounds like I missed you in Bham last week.

LTrumpore Added a comment about press release HotBars Introduces the World’s First Heated Bicycle Handlebar

Can confirm they actually work really well, and heat up enough to feel in about a minute. I was on a couple cold and wet Bellingham, WA group rides this weekend and there were two people running later-generation Hotbar prototypes and standard lock-on grips. Had no idea what they were until I asked about the plastic housing bolted to the bars - figured it was a mount for a storage bag or something - turns out it was a battery so I got curious. With my riding gloves on, the bars were in fact quite comfortably warm. I have no...

As a company, we prioritize performance and durability over weight. We could offer a fork that would be competitive in weight, or lighter than the European version you're referring to. I've said many times that they make a good product....it's just a different category than what we're building for. If we wanted to reduce weight and make an equivalent product to what they're building, we would have to remove the following items: - Coil Spring based spring system - Independent Hydraulic Bottom Out Damper - Sub Chamber with external adjustment - IFP based sealed damper - High Speed Compression with...

Oh interesting. Had no idea this was already done. @PUSH Industries I'm interested to what tolerance an effective "oil bushing" is to? Isn't that a great way to develop premature bushing play? Also what this is effectively doing is having a "burnished bushing" and filling the void with oil. In many cases burnished bushing can create more friction on heavy compression since the station has more wiggle room in the lowers/bushing and can go off axis easier. Would this not be the same for an oil bushing since it's easily movable? Yeah enjoyed that video. I really like what Henry...

The hypothesis-yet unproven-would be that while the difference in unsprung mass is too small to matter, especially when factoring in the weight of the wheel and tire, a targeted increase in sprung mass might be beneficial. Cycling in general has always been adverse to any weight gain, and as a result maybe we’ve overlooked where it might actually be of...

The sprung/unsprung mass is more of a factor in motorcycles than in bicycle forks. As you pointed out, the die-cast lower legs found in MTB forks are very light already. As for lubrication, there is a massive advantage there. With a conventional fork, ideally, the bushings are "sized" to provide the tightest fit to the the stnachion tube without binding. Suspension tuners often refer to this as "burnishing" the bushings. The reason this process exists is because of how difficult it is to keep fluid "splashing" between the stanchion tube and fork bushing. Our NINE ONE is different in the...

If memory servers me correctly (big if), the original 2005 era Fox 40 bushing/stanchion interface was claimed to be designed this way. They felt loose if you locked the front brake and rocked back and forth but felt solid when riding and fluid filled the gap. Given that this was over 20 years ago it may have been a positive...

Didn’t the RS-1 use a proprietary hub?

Probably one where the fork manufacturer designed their own proprietary hub to precisely control all tolerances and optimize the hub/dropout/axel as one system rather than separate ones. As far as I know the closest anyone has come to doing that was Foes with their 30mm axel - and maybe some of Sunn era custom Boss forks - but even then...

Again, coming from the manufacturer's perspective. You mention that "outsourcing a step will add a ton to the price". In reality, it's often outsourcing a step that saves considerable time and money. One specific example I'll share would be our shock shafts. We used to machine our steel shafts, complete with in-machine diamond burnishing process to the critical outside surface. The burnishing process was slow and required constant monitoring of the coolant ratio used for cooling and lubricating this process. Now, we outsource this step using an OD grinding operation to achieve the same results at a much lower cost...

Could for sure. But generally speaking, if a manufacturer is outsourcing a portion of the process it's not because it's going to add costs.

You're not going to find someone who knows more about the granular details of manufacturing than Darren, and he is correct here as well. I'm currently looking at cost breakdown of several part I'm having made with a supplier in Taiwan and it tracks with his experience outsourcing certain processes in the US. The additional costs related to surface finishing...
