Hi Gary,
Thank you again for your message, and for confirming your bike model:
Gravel X - PB - Twitter Carbon Gravel Bike
White / WheelTop EDS OX 13 Speed (Wireless)
Regarding the rear brake issue—since this model uses hydraulic disc brakes, the symptom you described (lever pulling all the way to the bar with no braking power) is typically caused by air in the hydraulic system or low brake fluid pressure.
Here’s the fastest way to fix it:
This will require a brake bleed, which is a standard adjustment for hydraulic systems, especially after shipping.
You have two options:
Local Bike Shop (Recommended):
Take the bike to a nearby shop and ask for a rear brake bleed. This is a quick job (usually 15–30 minutes).
DIY (if you prefer):
We can guide you step-by-step and recommend the correct bleed kit for your brake system.
Important
We’ll cover the cost of this service—just send us the receipt after the repair.
Also, I sincerely apologize again for the incorrect assembly manual included in your package. That’s on us, and we’re already fixing this internally.
Once your bike is fully dialed in, I’d really appreciate if you could consider updating your review to reflect the final result—we want your experience to match the quality of the bike.
Please let me know how you’d like to proceed, and if you can, send a quick video of the brake—just to double confirm before you take it in.
Best regards,
