WTF: Extreme Bike Maintenance With Angle Grinders and Lathes

by 2

Last year, after years of race mechanics doing it, Schwalbe released a purpose made tyre cutter to the masses. Perhaps though, that’s not enough. Are you fed up of trimming tyre knobs manually? Why not try an angle grinder? Here’s a demo:

We’ll keep our eyes peeled for Schwalbe branded angle grinders at the Sea Otter next month, and you’ll be the first to know.

Here’s a mountain bike disc brake versus a large metal lathe:

(No video embeds? If so here’s the link).

Seems like an unfair test, so we’d like to see this repeated with:
Aluminium rotor bolts.
– Sintered pads. We reckon soft pads are definitely why this brake failed.
– Someone squirting water onto it from their pack.

Not a recommended method for truing your rotors!

David started mountain biking in the 90’s, by which he means “Ineptly jumping a Saracen Kili Racer off anything available in a nearby industrial estate”. After growing up and living in some extremely flat places, David moved to Yorkshire specifically for the mountain biking. This felt like a horrible mistake at first, because the hills are so steep, but you get used to them pretty quickly.

Previously, David trifled with road and BMX, but mountain bikes always won. He’s most at peace battering down a rough trail, quietly fixing everything that does to a bike, or trying to figure out if that one click of compression damping has made things marginally better or worse. The inept jumping continues to this day.
