BMC - tickling your fancy?

Dear all, I have a problem with the Streampost of my BMC SL01 model 2011: it slips down. I wrote to BMC and they suggested me to go to Evans (the guys in Evans even don't know how to unlock the streampost) and "First of all, the basic adjustment must be correct in order to have the right clamping tension. Also carbon paste can be used to avoid slipping down. This should definitely solve the problem."

Do you have any suggestions?

Thanks

Mine has a layer of that sticky screen protector film you can buy for Your Ipad, and then some carbon paste. Belt and braces.

No longer using the Bebops SF?

Never had the Bebops on the BMC. They where on my commuter untill I broke them, and went back to crank bros.

Running Ti Keywins. Very light, very low, very solid feeling, and With a selection of axle lengths (mines a short). The float is between pedal and axle, so the cleat Connection always feel solid through the pedal stroke.
