DIY preferably.

Tied to a screw in the rafters in the garage. saddle through the noose. MTB-ing since 1989, and it’s served me well all that time.

I fashioned one out of wood that slotted onto the top of a wheelie bin. It was shit.

Good for cleaning and most maintenance jobs

That last one is very neat. I have an old Park one. It’s been fine, except with dropper posts and modern hydroformed tubes, it can be hard to find somewhere to clamp it.

I use a Thule Frame Adapter 982XT for bikes with droppers and top tubes that can’t be clamped.
