Tubeless - extended bolts

 As opposed to the tubeless SIP rims for Vespa, the Lambretta tubeless need extended bolts to work. Test fitting the drum confirms this.

 Reverse side...

 The tubeless rims are supplied with the necessary extension bolts. Now for the original rear drum I will have to machine out the existing bolts. On the new front diskbrake drum, I was able to unscrew ("links"!) the bolts by hand.

Extension bolts 10-15mm longer...

I will most likely leave the original bolts in before paint, and replace them with the extended ones afterwards.
