CTR ShunTai vs CTR Shimano 105 — Shifting & Braking System Comparison

Feature	CTR ShunTai Version (2×12 Speed)	CTR Shimano 105 Version (2×12 Speed)
Shifters	ShunTai integrated hydraulic shifters with a slightly heavier, mechanical feel. Shifting travel is longer but crisp and reliable.	Shimano 105 R7120/R7170 dual control levers with refined ergonomics. Smooth, light, and highly precise shifting response.
Shifting Mechanism	Traditional cable-actuated system, with minor delay between front and rear derailleurs.	Advanced Shimano mechanical or electronic system (depending on setup) for faster, more accurate gear changes.
Brake Type	ShunTai hydraulic disc brakes using mineral oil. Strong braking power but firmer lever feel.	Shimano 105 hydraulic disc brakes with mineral oil. Smooth, linear braking power with excellent modulation and heat control.
Brake Calipers	Aluminum dual-piston design, simple and easy to maintain.	Shimano BR-R7170 (or similar) dual-piston calipers with high heat dissipation and consistent braking.
Brake Pads & Hoses	Uses standard mineral oil and compatible aftermarket pads.	Shimano original mineral oil and pads, offering longer lifespan and higher compatibility.
Maintenance	Easy and low-cost maintenance.	Longer service life but higher maintenance cost.
Riding Feel	Suitable for daily commuting and entry-level riders.	Ideal for intermediate to advanced riders seeking superior shifting and braking control.
