| 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. |

Solid bamboo board set for the price
Color: Carbonized, Size: 3-piece
This bamboo cutting board set has been a nice addition to my kitchen. I like having different sizes available, and I especially appreciate being able to reduce how often I use plastic cutting boards. Mine did have a strong odor at first, but after washing them and letting them air out, that went away. They also seem good for the price

Awesome Boards….BUT the Smell!!!!
Color: Carbonized, Size: 3-piece
I’d love to give these 5 stars, they are heavy, well made, smooth, deep juice grooves, just nice….but the smell! I washed them, then used vinegar on them, set them outside over night, washed them again….its better but still present. I’d love some guidance on this. I’m hoping it goes away in a few days. It’s like a very strong woodsy smell that actually made my whole kitchen smell like these boards!
Edit: Ok, here's what I did. Washed, let dry, coated and scrubbed with apple cider vinegar, set them in a high air flow area for 24 hours (I put mine outside on the patio over night), washed and scrubbed again, let dry, scrubbed with lemons and salt, let dry, washed again. Finally, there is still a slight smell if you push them against your nose but that seems to be fading as well. So, great boards if you want to go stubbornly go through the smell removal process. I don't think it's a chemical smell, I think it's processed bamboo that is shrink wrapped in air tight packaging too soon after manufacturing. Anyway, I'll move this to 4 stars....but lots of work involved here!

Economical and descent for price
Color: Carbonized, Size: 3-piece, Color: Carbonized, Size: 3-piece
Pleased with price, style, color, and the 3 sizes of these carbonized bamboo cutting boards. Based on the reviews had the expectation of the "smell", which is the oil used to seal the cutting boards. (I suspect linseed oil was used based on the lingering smell, as the off-gasing process is longer. It's also cheaper than Tung oil and food grade mineral oil.) I work with wood and various oil sealants so the smell is a non-issue. As there are natural ways to speed that process up and minimize the smell. In addition, I will be using fractionated coconut oil or food grade mineral oil to seal cutting boards on a regularly basis (monthly or more frequent). As we live in a dry climate, hard water, and frequent use.
Appreciate the other reviews which lead to our purchase and reasonable expectation of these cutting boards.
