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. |

YOU CANT ALWAYS GET WHAT YOU WANT, BUT THIS PRODUCT DEFINITELY DELIVERS. GLAD I PURCHASED IT.
Size: 1 Fl Oz (Pack of 1)
I've been using a $49 bottle of retinol serum and found this to be just as effective and at a much lower cost. I could tell a difference in my skin in approximately 4-5 days. I can't smell any scents or fragrances and that's a plus for me. I thought it would stay greasy on my face, but it dried within 1-2 minutes. I'll definitely order again.

The Safe Sunscreen You've Been Searching For!
Size: 3 Fl Oz (Pack of 1)
5/5, 10/10, search no longer for the perfect sunscreen, you have found it! If you know someone fair skinned who will burn in the sun while swimming, this sunscreen keeps you covered. If you are at the waterpark, just reapply as noted on the tube. This sunscreen smells amazing and keeps you from burning. The lotion isn't too thick or watery, it is just the right consistency. You will not be disappointed with this sunscreen and bonus, it is reef safe so it is environmentally friendly. I have been buying this sunscreen for years and years and will buy it again this summer!
