Tubeless GS1100

[Guest]

Well I finally got around to changing the way old Dunlop rubber on my 1100. Thanks to everyone that chimed in on the tire size questions I had a week or so ago. I went with the Bridgestone Spitfires and removed the old Dunlops via the wanky harbor freight jig.

I thought these diecast rims were tubeless? To my surprise, I found tubes.
Is this common?

I drilled out the rims with a step drill and popped a stem on the rim, slipped on the new rubber (which weighed like 6 pounds less than the old dunlops)
and everything is peachy.

Just wondering if anyone else runs tubsless on these diecast rims?

have run tubeless, just need to watch the rim to make sure it is clean as corrosion has developed and caused slow leaks on mine.

That's good to know. I rubbed the rims down (where the bead would be) with some good sandpaper and made sure there were no big dings etc. I'll keep a lookout for corrosion.

This thread is a recent discussion about running tubeless tires on the old cast rims. Lots of info about making this decision.

While lots of people do it, there are two things of concern:

Safety of tubeless tires on rims not designed as such, and,

Insurance companies possibly denying a claim or insurance if properly certified and compatible tires and rims aren't used.

Where I live we are seeing increasing scrutiny of bike crashes and mention about safety issues. This is one example
