BOX ONE RACE PREP EXTERNAL BOTTOM BRACKETFor years, pro BMX racers have modified their bottom brackets by removing the seals and replacing the grease with oil. This results in free spinning cranks, but also significantly shortens the life of bottom brackets. The Extremum RacePrep bottom bracket is the first external BB designed for BMX racing. Unlike mountain biking where bikes are exposed to mud and water, BMX racers typically ride in relatively clean environments (dust not withstanding).

Despite all the positive reviews, I believe this product is subpar. There are genuine sheep skin Hydes but this product is NOT it. There is no leather embossing showing authenticity, and many signs of strong chemical treatment. Smell is lingering and I've aired them for over two days. Not very comfortable since the fur is very thick and coarse, you would expect it to be softer for the price as well. Not premium quality. I ordered this for my children to sleep on at long evening Church services but now I will look to more niche sellers for a higher quality product.
