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. |

Great little boy blazer
Color: Dark Blue, Size: 8, Color: Dark Blue, Size: 8
Too adorable and good quality. My picture doesn't do it justice. A nice dark blue with a subtle pattern. Will go well with many outfits. Fits well and not too snug with a shirt or light sweater underneath.

Long sleeves
Color: Dark Brown, Size: 14
Looks so good on my boy. I bought a little big (size 14 for my 11 year old) and turned the sleeves in a couple inches, which requires moving the buttons, but I think he might get a couple years wear as he is probably about to hit a height growth spurt. It doesn't look cheap - the material is thick enough to drape nicely.

Surprising quality, excellent attention to detail, and satisfying shopping experience
Color: Light Grey, Size: 4
This shopping experience was fantastic. First of all, its quality definitely exceeded its price, and the texture is very good
Very thoughtful, great attention to detail, absolutely standard suit!!!
What I love the most about it is its fabric. It makes me feel at ease when my child wears it, and it won't be uncomfortable to wear. It's very child friendly
I have no doubt about the size, its waistband is adjustable, at least for my son, it fits well

Look and feel awesome!
Size: 11.5, Color: Optic White/Opti
These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!
