I have been bashing away on a set of the Continental Rubber Queen 2.4′s for around 4 months now, and I must say this is “Meaty Beaty Big and Bouncy”. These are big suckers, that is just a blast to use, and they love to haul ass through the meanest territory you can throw at them. Yes, with these babies size does count!
UPDATE: Continental renamed the tire Trail King instead of Rubber Queen
The Rubber Queen is a new tire for Continental, and it joins their other existing Downhill, Freeride and All Mountain tires the Der Kaiser and the Rain King. The Rubber Queens come in a 2.2 x 26 inch and 2.4 x 26 inch size in both a normal and UST version. The normal version is made with the proprietary Black Chili compound and have the Apex sidewall treatment, and all versions are handmade in Korbach Germany (the Mothership).
The Rubber Queens casing is comprised of nylon fabric, which has an extremely high tensile strength, and can withstand the abuse the real world tosses at it. The normal version is constructed of three plies of 60 tpi (3/180) bias cut material that make up the casing under the tread and two plies compose the sidewalls, while the UST version uses three plies of 110 tpi (3/330). Tpi is the number of threads per inch, a finer fabric is more flexible and puncture resistant while a coarser fabric is more rigid and cut resistant.
The proprietary APEX sidewall treatment puts additional material above the tire bead to help protect, stiffen and stabilize the sidewall for better control and cornering. The stiffened sidewalls can take more abuse and allow you to bash the tire around with abandon. It is supposed to help reduce pinch flats, but I got plenty of them anyway, so minus 1 for that attribute.
The Black Chili compound is a new tread mixture, which blends newly developed synthetic rubbers with proven natural rubber. They contain ‘nano’ (10 nanometer) sized rubber particles that have surface properties optimized for use in bicycle tires. These smaller particles enable the tire tread to deform around surface objects more quickly, improving grip. They also form a tighter bond with each other, thus improving compound strength for improved tread life, and fewer chances for lugs to rip, and tear. The way in which these particles interact with each other also lowers rolling resistance.
Out on the streets for a living
Pictures only begun
Your day is sorrow and madness
Got you under their thumb
Whoo, black chili, yeah
Whoo, black chili
