    Tubeless Blues

    At times it seems completely random what tubeless tires will work with a given rim. Yes, there are standards but my experience so far is that the standards are at best a starting point for working out what tires and rims are compatible.

    FLIR is a company that makes thermal sensors at varying price points.

    The Future of eBikes: How Fast is Too Fast?

    Well, precisely, some modern winter base layers. I often think that merino wool is as much marketing hype as technical performance. Merino wool, on the average, can absorb more water than synthetic technical fabrics and sometimes takes much longer to dry out when it does become wet. Merino...

    The Future of eBikes: How Fast is Too Fast?

    There is a lot of technical gear nowadays that uses wool. While it isn't as stinky I find even the very best wool to be a lot less durable, especially for very thin or very light layers.

    The Future of eBikes: How Fast is Too Fast?

    I'd argue nearly all outdoor sports do to one degree or another. Take hunters and camo. They even wear camo under the bright orange vests they are required to wear to avoid being shot by other hunters who might mistake them for a duck. A lot of outdoor sports have a pretty specific dress...

    Bosch discontinue features.

    I'd argue that in 2017 or 2018 they were something special. But their designs really haven't moved on from what they made back then and the state of the art has moved on. So yeah, kind of like an old iPhone.

    The Future of eBikes: How Fast is Too Fast?

    You jump to a lot of conclusions about how much spandex I might own and wear. Based on my experience, inevitably in a larger group someone ignores or stretches the limits of courtesy to other people. And what happens then is that other members of the group see that person doing it and...

    The Future of eBikes: How Fast is Too Fast?

    Let's just face it, it is hard for any organized group of cyclists to not completely hog whatever road or trail they are riding on. Best to do this activity in very small groups or solo.

    Wireless Earbuds for cycling

    If you look at the trainingpeaks app it kind of does that. I often use a polar HRM and their companion apps can call out pace and heart rate zones while I exercise. Through the same headset that I am listening to music with.

    Wireless Earbuds for cycling

    I'll give an upvote for the Shokz too. Usually I only wear them on quiet grade-separated bike paths and gravel roads. They do make long uphill grinds go much more quickly.

    E-Gravel Bike…Looking for Advice

    Yeah, but some of them are pretty predictable. Most of the compute grades by sampling the elevation profile periodically. So if they sample every 100 meters they will obviously average out a steeper section shorter than 100 meters. I suspect most of them sample less frequently than every 100...

    E-Gravel Bike…Looking for Advice

    Most cyclists and most bikes will be pretty much defeated by any grade over 25 percent, even for fairly short distances. I'd also point out that very long sustained grades that are "easy" in short doses knock the stuffing out of most cyclists. One route I sometimes ride near me climbs over...

    From Concept to Prototype: Ultra-Light Ebike Kit for Road Bikes Now in Development!

    The purpose of a torque arm is to keep the axle from rotating out of the dropout. With a through axle you don't have a dropout. You have a threaded hole the axle goes into. And it is threaded so that even friction from the wheel rotating in a forward direction will tighten the axle, not...

    E-Gravel Bike…Looking for Advice

    My short answer is if you'd find it scary to ride down it is probably pretty steep. Sustained climbs of over 1000 feet per mile (so around a twenty percent grade) are pretty tough even on e-bikes that are the stoutest climbers. Any climb of that grade longer than a few hundred yards is going...

    Anybody tried Clik tire valves?

    This is my own opinion. I think there is zero justification for running with tubes (outside of an emergency when you ripped your tire and are limping home) on low-pressure high-volume tires. So generally on any tire of three inches or larger tubes make zero sense.

    I suspect you wouldn't need a torque arm if your conversion has a through axle. And if you did it would look really different than conventional torque arms. Also, it is 2025 not 1975 and the way you attach a wheel to a bicycle is with a through axle.

    Anybody tried Clik tire valves?

    I'd watch Schwalbe's web site. Where last I read clik valve tubes were "coming soon". My own feeling is the really huge win with Clik valves is for tubeless and since most Clik pumpheads will still inflate Presta valves you can get buy with a Presta valve tube to limp home when your tubeless...

    The Future of eBikes: How Fast is Too Fast?

    That is a completely idiotic straw man argument and doesn't even appear relevant to our discussion here. And a lot of countries out there are doing far better about motor vehicle safety than the Untied States. And doing it without banning cars.
