Road Bike Frames, Wheels & Components / Re: LTWOO ER9 & ERX - Electronic groepsets

My ER9 brake calipers are solid. Instead of doing a full bleed, for regular maintenance I always do the top-off method by placing a funnel on the hydraulic screw port, fill it with mineral oil and then pump the brakes to remove air bubbles. I repeat the process on the other brake/shift lever.

I run the V1 ER9 calipers, the V2/V3 EGR calipers and a pair of GRX calipers with Ultegra levers on another gravel bike. I do the same method on all bikes. No issues. It's nice to have mineral oil compatibility across all platforms. This is the reason I'll never ride SRAM and their DOT brake fluid nonsense.

Do you attach the funnel on the break calliper port or the shifter itself?

I’m 179/75 and use a L. Got muscly thighs but they fit well. Haven’t thought of them being too tight.

ER9 user here. The 2mm hex screw in my front R shifter keeps getting loose after a couple of hours of riding. I set it up perfectly before i leave and while out on longer rides i have to push the brake lever further and further in to get the same braking power… Anyone else had this problem, if so do you have a fix or any idea what to do? I have bled the brake multiple times and i can always tighten the screw to get it to work perfectly again. But it would be nice not to have to do it… My left shifter works perfectly.

Got the Cheji bibs with the red pad. Very comfortable and great great value. Will never pay more for bibs. Just ordered 3 more pairs.

Road Bike Frames, Wheels & Components / Re: Xmcarbonspeed CS-R01 build
« on: June 27, 2025, 04:00:19 AM »
I built up this CS-R06 with 50/33 carbon rims from Xiamen Carbonspeed as well. Very very happy with the end result. I’ve done around 800 kms the last couple of weeks and it rides like a dream. Peter was a pleasure to deal with as well. LTWOO ER9 group set (works very well and super easy to index with the app), 11-28 11SPD 105 cassette, GP5000 30mm tires, 160 rotors, Magene PES crankset with 50/34 (might go for a 52 next time).
Only trouble I had during the build was to fit the LTWOO RD cable trough the chain stay. But that’s more of an LTWOO problem than XCS. Files it down for 10 minutes and I popped trough. Remember to ask for the carbon rail seat mount. I forgot to but sourced one trough Ritchey. Rose bikes use the same saddle mount system.
First bike build and it feels like flying around 40 km/h. Very happy. :)

Maintenance, Mechanics, & Tools / Re: Which immersive wax are you using?
« on: May 10, 2025, 06:37:34 AM »
You’ll need a fully refined Paraffin wax. Oil content lower than 0.5%. https://www.petronaftco.com/semi-vs-fully-refined-paraffin-wax/
You can get it in Europe here. https://dwoil.de/en/shop/paraffin-waxes/paraffin-wax-52-54-c-solidification-point-as-granules-fully-refined/
From 1kg and up. Shipping is expensive though. I’m ordering some.

Hey Sebastian
I’m very interested in buying it. Can I shoot you a DM? I live in Denmark so if you’re fine with sending it to your neighbour country it would be awesome. :)
