There’s no doubt about it, I always wanted a maintenance stand. A couple of years ago I got one for Christmas (after lots of droning on about the exact one I wanted – started in October if I remember correctly).
Everyone should have one, yes you can manage without, but it’s a joy to have one and fiddling with gears (if you are derailleur person) or brakes is much less, errr, fiddly.
My stand can hold the bike at any angle and the height is also adjustable which is lovely. It can hold the bike via the seatpost or the frame (which is a nice feature for step-through “girlie” frames).
The stand I have is a Park Tool PCS-9 Home Mechanic Repair Stand.
Last night I fitted new brake pads and I was reminded how nice it is to have a stand to lend a hand.
