Tyre Pump question

    There are a few tricks to make it easier on a typical bike: first of all, put the bike in top (smallest) gear at the back; secondly, once the wheel's between the stays, position the axle so it is inside the bottom of the chain run and hook the smallest gear into the bottom run of the chain; then pull the wheel up towards the dropouts (where the axle normally sits and is tightened against). If it doesn't pass the derailleur gently (which happens mostly on some bikes which are fitted with smaller tyres than their maximums), then don't force it, but push the front of the derailleur, which is attached to the upper jockey wheel (the cog that the chain runs around "inside" the loop, if you see what I mean) towards the back of the bike and the wheel may then move easily into the dropouts, or you may need to push the bottom of the cage by the lower jockey wheel down towards the ground too.

    It's easier than that description sounds but I didn't find a good youtube video showing it clearly. Most of them used bikes without mudguards (which means you don't have to lift the bike so high) and all of them used derailleurs which don't need the cage to be pushed. This is better than many but I think you can usually hook the gear on the chain without grabbing the chain like he does:

    (edited to fix punctuation and added a comment about which bikes don't need you to push the derailleur)

    Thanks for the video. There's a lot to this cycling malarky!
     
  3. There is and there isn't. Some people just ride their bikes and do just fine and dandy.

    So I guess there's not enough room in my saddle bag for a co2 pump what with the other stuff in it? So I perhaps I need a mini pump to attach to these two free bolts I have on the frame? 20180123_151951_1516720892808-1.jpg 20180123_151959_1516720893385.jpg
     
  5. I have a pump that sits next to a bottle cage on the frame a bit like the image below. The CO2 cartridge, adaptor and spare inner tube are in the saddle bag.

    Thats neat! So I need a hand held mini pump (not bothered so much about co2 the more I think about it) and attach it to my existing water bottle cage or to the front on those bolts?

    Whatever sort of pump you like, attached wherever you like :smile: I put mine in my saddle bag, but it's almost as big as @raleighnut's

  9. Correct. But don’t dismiss co2. It’s super quick and can sometimes get you higher pressure than a mini pump can.

    So how can I tell it will attach to the bolts on my bike or behind the water bottle? I have the same query with others I look at or is it a given it'll work? I can just see myself faffing around with cable ties for a wrong 'un

    Bottle cage mounts are pretty standard as are bottle cages and the side pump mounts that accompany them and generally one hole is a slot to accommodate slight variations.

    I think I need a new bottle cage mount then that can accommodate the pump as well. The one I have below is too simple?

    The mount goes under the cage, it is possible you may need slightly longer bolts but the ones you have may be long enough. You only have about 3/8th"- 10mm of engagement before which the bolt is simply poking into the frame beyond the fixing (and not doing anything) though so often it will be long enough.

    I've got a topeak pocket rocket and a specialized air tool on my bikes. Both are mounted on the bottle cage bolts.
