CTR ShunTai vs CTR Shimano 105 — Shifting & Braking System Comparison
| Feature | CTR ShunTai Version (2×12 Speed) | CTR Shimano 105 Version (2×12 Speed) |
|---|---|---|

| 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. |

Taste good
I like the flavour, not too sweet, the only thing is they take a while to dissolve

Weird taste...and no fizz....
I presume these do what they are meant to do...replenish electrolytes (although how completely you need replenishing, meaning needing other minerals besides what are in these Idk)
However, the whole reason I would not repurchase is the taste is ...OFF. For some its not that strong, but for me its TOO strong, I want a subtler lemon lime taste (or any other flavor) basically a sugarless Sprite taste. And if you're looking for fizz to truly make it a flavored seltzer water experience, Nope.
