So, after roughly 40.000 shifts of flawless performance, my groupset is finally showing issues: I'm experiencing battery drain. I came home from a vacation trip and the bike was stored on the wall for a week. The RD was dead because the battery was fully drained. I recharged it to 100%, went out on a 90min ride and it was down to 82%. After leaving the bike for another day it's now at 59%.

Has anybody with these kinds of issues found a cause and/or solution? The batteries have given me zero trouble so far. I doubt that that's what's causing the problem. I'm gonna clean the plugs and connectors and weatherproof them and see if that does anything.

 have you tried replacing the batteries...  they can get weak and break down from constant drain... Kinda like phone batteries dont last as long as they used too after a year or more.

I should still have my 2 from my frames since both bikes are AXS. I'd be willing to ship if you are USA

Velobuild send me the hose through piece  that I already have and not the stop.. If you have the hose stop. I would like it please.

SOLVED!!!!

the type wasnt seated quite right!!!

I was reading that tubeless sealant might contaminate the pure nitrogen, so you won't really benefit from the longevity it'll provide from pressure loss. There's also the possibility the sealant won't react properly sealing punctures since there's less oxygen in the tires. Though I'm no chemist, so for all I know everything I read was just BS and it'll work great!

Though if you can get free nitrogen at Costco and the container only cost like $35 USD, I'd get it as a cheap way to have pressurized gas for beading tires. I'm too cheap to get a compressor so I usually just bead my tires at the gas station pump.

Omg  "tubeless sealant might contaminate the pure nitrogen thats rich"... the air we breathe is 78% nitrogen.

as for "There's also the possibility the sealant won't react properly sealing punctures since there's less oxygen in the tires." That sounds more likely but there is the outside o2 that causes hardening. Sealant actually has lil fibers that form the structure of the patch. and then hardens.

One way to fix this is "set" your seatant with normal o2 and then after a ride of 2 switch to nitrogen... Because then its already ready. but then it does then leak out the tire... so who knows.. I would think if you set it it would be fine... but I wouldn't do it.... maybe if I was top athlete in the world trying for any edge... but day to day riding its silly.

Oh thats an option....well I was looking at making it in brass of something. I would to need to re do that design to make it better.

I was also looking at these as an insert... https://www.amazon.com/Saiper-Bicycle-Housing-Ferrules-Derailleur/dp/B082YBN86J

I was also hoping vb gets back to the email I sent them too.

I am running a sensah system.... I dont know how will shimano  work... this is a more budget built. There is a scram on there right now

how do I mount the front shift cable at the derailleur??? you know to stop the housing to it shifts? anyone have pics...I feel like I have a missing part. the housing just comes out of the bracket of the seat tube... its whats holding up my bike... I should have asked before but I am very adhd and there was no more dopamine in the project... so I have to wait to recharge.
