TheKaiser Added a reply to MTB Handlebar Diameter Debates - 31.8 vs 35 and more
1/26/2026 4:17pm The Vibrocore bars are supposed to reduce vibration, but counterintuitively, that doesn't necessarily equate to more flex. If you think of a tuning fork, it vibrates/resonates after being struck. Now imagine sticking a piece of soft foam between the legs of the tuning fork and striking it again. The vibration/resonation will be hugely deadened. That's essentially what the Vibrocore foam...

8/23/2025 2:13pm Wow, you are really doing it right...No corners cut here! That is interesting that your thought is that a shock with more of a compression damping platform is advantageous to control the linkage. Intuitively, I tend to think of links as being more supple, due to decreased bushing bind, so I would have thought maximizing that strong suit by keeping...

8/21/2025 2:34pm Wow, that is a very slick and professional-looking one-off prototype fork...it almost looks like a sellable product as-is! Looking forward to ride reports and updates!

I wrote a lengthy post on another forum back in the day when they gave up all their US production and predicted that would get them in trouble. Previously the arguments for them were short turnaround times because of in-house production (early production 29ers, 27.5ers), constant evolution of "same model year" frames (small modifications between batches when they found a better solution, e.g. additional/differently placed cable stops), and made in the US. They had a unique selling point in "made in the US" that they gave away because of the wish to grow and go carbon. Now they have to...

Can we get some insight on how intense happened? From what is literally the hottest bike (the old M1) to now. Have a soft spot for them, thought about buying the new M1, but this feels like decades of bad decisions leading to this point.

To be fair its not like the other manufacturers have vastly superiour policies or reliability. Plus people like to shit on shimano but they actually have kept the same motor mount for almost 10 years now. This means if your motor craps out or you're dissatisfied with the power on your old e8000 you can get a new or lightly used more powerful motor for relatively cheap. (lightly used motors start from 300-400€, new starts from 600-700€ in europe) But yeah, they should offer cheaper replacements or spare parts. Its simply uneconomcal and not at all environmentally friendly to basically...

Damn! Did we work together? :D Only bit I would add is pull the lever slowly/lightly. If there's an internal leak, it may hydrolock under fast/hard pulls and give a false negative for the internal leak. A couple pages back I listed out the steps for diagnosing a mc piston leak, hose leak, or reservoir issue. Situ can be modded here on by setting the lever in the bleed position and popping the cap off to observe what the fluid is doing.

7/22/2025 10:33pm Not claiming to have any sort of magic solution, but if the increase in lever throw followed a sustained pull (for example, on the steepest part of the trail) then it could be a cracked inner liner in the hose. That can lead to fluid leaking into the braided reinforcement layer, without any visual indicator, other than perhaps a slight...

7/24/2025 5:12pm Yeah, and Shimano seems to be doing something interesting with the overrun too. In the previous few posts, we were discussing how some people find the Bosch overrun in EMTB+ mode can be a little excessive. If I'm not mistaken, Shimano has either an option or a default setting on the EP801 whereby the overrun is cancelled by a slight...
TheKaiser Added a reply to E-bike talk: not tech rumor derailment
7/19/2025 9:31pm Is there not an adjustment to lower the overrun in EMTB+ mode, independent of the other settings? I guess even if it does exist, you might not want to lower it if you happen to like the overrun in other terrain and just want to turn if off for switchbacks and whatnot.

7/12/2025 5:03pm I like both your thought experiments and proposed real world experiments. I did not know that brake fluid was such a poor conductor of heat, that is really interesting. Having said that, am I crazy to think that getting even a small layer of the fluid up to the boiling point could be problematic? In other words, these hypothetical hot...

5/16/2025 3:32pm Pinion MGU bro! Also, Cavalrie has something coming out and there are a few other prototypes out there, but Pinion is the one getting traction and spec on actual bikes you can buy currently.

This thing is WILD! We really need more info on all manner of aspects of it, as it brings up so many questions that aren't answered in the inclueded info. Why the "skip tooth" sprockets on the secondary drive system, and are those magnets or springs I see on the 2ndary chain tensioner? How about doing an article/interview with the owner or maker to talk about this machine's inception and manufacture?

The trails I ride aren’t overly technical- loose over hard surfaces with a few short sections of rock gardens. I find 130mm mode is sufficient and really efficient for the flatter sections and climbs. 140mm mode allows more speed on the technical sections without too much drawbacks on the the flatter sections and climbs. 152mm mode is faster still on the technical sections, but I notice it doesn’t feel as sharp on more mellow parts of the track. I’ve only used 170mm mode twice and it’s definitely overkill for my local trails and to get the most out of it...
