Have done a couple rides now with my un-bent hanger and re-adjusted derailleur. Not a single missed shift or popping off a sprocket. Lesson learned: If you’ve adjusted your derailleur and still have problems, check for a bent hanger. It’s really hard for derailleurs to overcome that...

The SRAM GX wireless derailleur is under $530 now at Amazon. The blurb claims: Is this really true? On my Ultra bike, I've got a Shift Sensor installed to pause the motor when shifting. Obviously, with wireless the Shift Sensor has no wire to connect to, so I won't have that. BUT, if it's...

The SRAM GX wireless derailleur kit is now $528: https://www.amazon.com/SRAM-Eagle-AXS-Upgrade-Kit/dp/B091TJ3CJL But, a bent hanger will mean that somewhere along the travel the derailleur is mis-aligned and whether it's shifted by cable or electronically, especially if the cable is simply...

Yeah, I added a Park DAG-3 to my cart earlier.

Took another more strenuous ride this morning. Had it pop out of gear a few times. So, back home, just looked at the cage relative to my wife's almost identical bike, and yeah, the cage was tilted compared to the wheel. Put a big wrench on the hanger end with the derailleur still attached and...

Hmm. Technically, your hub, suspension pivots, motor & battery, and anything else that gets hit with a 1500psi pressure washer needs an IP56 or IP66 (second digit is what matters for liquid) rating. I'd be concerned that not all those components are up to that spec. Muc-off sells a...

I was doing some testing on Pedal Tab's "Slow-Start Mode" setting, confirming that for my setup changing the value from "2" to "7" and back had no effect on start-up power. In the Torque Tab thread, I postulated that Mike/Frey's Bafang Ultra Programming / Bafang Ultra “Smooth” tune claim that...

Back from my 16 mile ride. Shifting was crisp overall. Between wind noise and Bafang Ultra motor noise, I couldn't hear any clicking.

SRAM 12 speed GX drivetrain (mountain). After several off-road rides, one of which included some pedal strikes, noticed my bike wasn't shifting well. The usual cable length tweaks didn't solve the problem. So, cleaned the bike, re-oiled the chain, and proceeded to setup the derailleur as if from...

Most sources quote ranges from about 10 watt-hours to 25 watt-hours per mile. For instance, this. Let's say 20 watt-hours per mile. Let's say electricity cost you $0.20 per kilo-watt-hour, which is more than even CA according to this. Let's say your charger is only 85% efficient. (20/1,000 *...

Good point, but the real answer depends on the specific geometry and how much stuff you're carrying. A Specialized Tero X 6.0, for instance, has a rear rack mounted to the rear triangle: While this bike is designed for rear panniers, you can see that if you figured out a top of the fender...

It will be interesting to see what programming you end up doing after your previous participation in the "Ultra Tuning" threads before you owned an Ultra.

If you don't want to wait for a shipment from China, you can try these US/European-based sources: Luna: https://lunacycle.com/luna-750c-full-color-display-for-bbdhd-and-bbs02/ ($90) Varstrom: https://varstrom.com/products/display-750c (they have it with and without Bluetooth for $90 and $70)

But, it does actually say that in the manual, even the the US: bolding added. Whether this runs afoul of the US's "Right To Repair" laws is another question.

This is pretty basic, but dropper posts were invented for mountain bikers to lower (or raise) the seat using a handlebar-mounted quick release. Many like to lower the seat for downhills to let them have more control and use their legs as shock absorbers, but want the seat higher for level ground...

Hard to know exactly what you're saying here, but I'm guessing: 1) Front axle screws into threads inside the axle hole of the fork. 2) Rear axles has a separate nut into which the axle threads. The procedure for removing the front axle is to loosen the lever, then rotate anti-clockwise to...

100 posts and not one mention of the alternative of using a dropper post?

For many of us UART Ultra tuners, it's not about raw power, but a finely tuned delivery of that power that is controllable mostly by applied pedal torque. I personally would hate a bike that lifted the front wheel as you describe. I want my bike to take off smoothly and evenly, and have the...

Just a note that I've been doing more and more off-road riding lately. Here in NorCal, on the John Nicholas trail and the Aquinas trail up over Montevina from Los Gatos. I continue to be happy with the spacing of the pedal assist levels I've outlined. And so far don't see a need to change the...
