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. |

Worst item ever
Color: White, Size: 16in
Set up shelves and not sturdy at all. Followed the instructions perfectly. Very poorly made. I don’t have the box and now I’m stuck with the item.
Garbage can here it comes.

There are better floating shelves
Color: Rustic Brwon, Size: 16in
Doesn’t feel very sturdy like other floating shelves I’ve bought, and they slant a little. The anchors and screws that it came with all broke so we had to get our own for it to feel more secure on the wall, but still feels wobbly. Overall, it looks good on the wall after the fact, but won’t be adding too much weight on it.
