eMTB Round-Up: FSA Riva Bike Festival 2026
@justridingalong1: Same. Now I just zip tie brake hoses to the downtube. It's not pretty, but resistance never is.

Review: Motion Instruments System 2 Data Acquisition Kit
It would be impossible to do a ton of runs in one day and ignore the role of fatigue - so instead you'd be relying on timing results in variable trail conditions from different days, which isn't fair for each tune. It would also be impossible to hit the same lines every run - but also note that one tune could give you the confidence and control to hit different lines than you might with the other tune, which is overall a win. More sensor data would really help tell the story beyond timing results. 28 runs is a lot. If one tune is definitely better than the other, you may be able to get statistically significant results with way fewer. Either way I love your thinking here!

First Look: Look's X-Track Power Meter Pedals Cost a Cool $1,099 USD
The development time for electronics/power meters is insane. That side of this product was easily 10x+ the time to develop a pedal (which this also is).

Nerding Out: Why You Shouldn't Worry About Pedal Kickback
Good article mate. Nice and to-the-point. Pedal kickback or not, sure sounds like there are some merits to riding down hills without pedaling :)

Review: RockShox' New Flight Attendant Suspension System
Neat! I see a cool opportunity here to make the pedal sensor power-based using a power meter (and I'm sure they do too), and grade the compression based on how hard the rider is pedaling. The added bonus is that the rider can record and analyze their power with just the one sensor. The new Rival spindle pm would do the trick nicely.
