drillium

The density of grease is surprisingly close to aluminium🤔

I remember well the state of my hollow-pin chain half way round a mtb race🤣 but at least steel has a bit more weight to lose.

Drilling fell out of fashion when aero became king.

If your race was entirely uphill, the weight savings might exceed losses to air resistance😉

Who said anything is greased?!* ;)

Love drillium, but it's more of a look for me than weight saving. Always feels good to get expensive bike parts and chuck them in a lathe/clamp on a milling machine or drill press to modify them... as long as they don't come flying out of the chuck or work lose mid machining! 🤣
