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.

Firm and comfortable
Item Package Quantity: 2, Size: Standard
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

Full, Fluffy & Perfectly Supportive Euro Pillows!
Item Package Quantity: 2, Size: European, Item Package Quantity: 2, Size: European
These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!
