2012-02-03 initial post
If you have been a good boy (or girl) and have read through my blog you might remember that before I started my "let´s see how many rollers we can remove conversions" I was thinking of getting light Dr.Pulley sliders and see how they would work out. Sadly Dr. Pulley sliders have to be mail ordered from overseas and even that proves a challenge because of the limited weights at that time and virtually no dealers.
Now some years later and with 2 sets of the once reliable Piaggio rollers failing horrible it is time to look for safe alternatives. As it happens I stumbled across a Dr.Pulley seller in Germany who has a lot of different weight sliders from the original 21 gram down to 14 gram and you can even order 13 gram.
After some considerations I decided against the 8x13 gram and will see how my favorite Colt Conversion works with Dr. Pulley sliders.
I ordered the 2517 8-21 for the quite steep price of 45 Euros ($60) plus a moderate 3.50 for shipping.
This will be a long-term test to see if they are as good and reliable (37000 km) as the original Piaggio rollers once were. (In case you are not familiar, nearly every European scooter has an engine made by Piaggio and the OEM parts like belt and rollers are also all from Piaggio.)
