2025 RockBros ATS

I like this bike because it represents 100+ year old design in a modern machine. It's frame, wheels and brakes are virtually unchanged from old styles but with updated materials and component technology. Lots of aluminum, weighs just over 22 pounds.

Aluminum

Fork/Headset:
Aluminum / Threadless headset

Crankset/Bottom Bracket:
Aluminum single 45 tooth crank / Sealed bearing BB

Pedals:
Aluminum

Drivetrain/Cog/Chainring/Chain:
Sunshine 10 speed cog / Aluminum chainring

Derailleurs/Shifters:
10 speed rear derailleur and shifter / No front derailleur needed. Brand is SENSAH. Not familiar with it but I'll see how long it lasts.

Handlebars/Stem:
Aluminum

Saddle/Seatpost:
Simulated leather / Aluminum post

Brakes:
Aluminum dual pivot side pull

Front Wheel/Hub/Tire:
Aluminum wheel / Sealed bearing hub / Innova 700x28C tire

Wow. That's a pretty big chainring. According to a spec sheets I found, the lowest gear combo is a 48t to 28t. Yikes. Most folks would be walking that bike up any moderate to steep hill. Love the color...and the fact that it doesn't have disc brakes!

Chainring is 45 and low gear on cog is 34. I climb hills just fine.
