gonna reach out and see if he’ll sell me these

PSA if you’re still paying out the ass for thumbies: shimano bar-ends fit and work on these microshift jawns Universal Cycles -- MicroShift Road Pull Thumb Shifter Mounts [Y-BS204]

[Dr_Jart_Attack_PhD]

Yeah it sorta had my attention when I was thinking “oooh this could be nice for a flatbar conversion on my LHT” but as with only a right hand shifter it’s not that useful or economical shartmo

[Crustradamus]

is this thumbie porn?

@JUGE_FREDD

core maximum lighting setup is:

USB-C battery → special USB-C PD cable + barrel jack → german ebike headlight

for extra bikepacking credit also add:

Dynamo → USB charger → USB-C battery

is there any reason one couldn’t run a regular dynamo on a usb battery pack? i’m thinking about this for a second, non dynamo wheelset on a bike with a dynamo light

[Face]

Dyno is AC, e-bike lights and batteries are DC.

You could probably use an inverter, but then probably be better off with an e-bike light.

[karl_dandleton]

doesn’t the front light have a rectifier?

[crowding]

Generally yes, you can run a lot of dyno lights off a battery but since batteries aren’t inherently current limiting like dyno coils, you need to be careful figuring out a safe voltage, maybe use a lil dc-dc converter board to fine tune the voltage… At which point you’ve really just recreated an ebike light.

[JUGE_FREDD]

The LEVAL gimbal shows up having an interesting little legal addendum slipped in

The manual explicitly gives instructions on how to wire it to a power bank, especially for powering the gimbal separately from DC with an AC dynamo light — but the addendum says that’s illegal in Germany with a stub website saying that it’s only for e-bike lights wired in a fully StVZO fashion Leval - Bumm

basically “mommy and daddy are fighting”

[karl_dandleton]

hmm i thought the voltage limiting happened at the light. but i also don’t know a lot about this. i’ve seen dynos put out a lot of voltage on a meter just spinning them in a vise. but that’s not really current all by itself

ITT: Fred plays the game long enough to become a villain.

@karl_dandleton

two things- i’ve long dreamed of an stvzo gimbal or a switch and two dynamo lights- stvzo for the road and other for when the pavement ends. also holy fuck 300lux jesus christ i need it

I love these bikes but the named-after-prisons part bums me out
