Dr.Pulley sliding rolls in the 20x15mm format, weight 11 grams, 6 pieces / package.
Dr.Pulley rolls produce a much better acceleration performance than regular roller weights. They are precisely manufactured from a special nylon material that is characterized by particularly good sliding on aluminum (the material of the Vario). The abrasion is minimal and the dreaded one-sided flattening of standard roles are not possible. Unlike normal vario rolls Dr.Pulley rollers have an up to 15x longer life.
Dr.Pulley recommends that you choose the weight of the SR role sliding around 10-15% below the weight of the series role. Then a significant powerful acceleration results in an almost unchanged top speed and fuel consumption. If the weight is chosen to equal the original weight, the acceleration is slightly stronger, but may slightly increase the maximum speed for the same or even slightly reduced consumption.

Ordered as part of an upgrade and followed the suggestions here to replace the original part with about 10% less weight.
Measuring the original roller weights - 72 grams (6 x 12 gram) replaced with SR2015/6-11 - 66 grams (6 x 11 grams).
I have to say I am quite pleased with the purchase since Dr.Pulley rolls allow the engine to rev higher (sounds great too) when accelerating harder and I have not noticed a considerable change in fuel consumption in my daily commute of about 25 miles.
The upgrade included new roller weights (SR2015/6-11), and sliding pieces (SP2015-K), also a new Malossi kevlar belt and Dr.Puley Hit Clutch (HiT181401), hope that helps when picking your parts.
