    make sure there is 5+mm free space between the bottom bracket cup/flange/sleeve and the crank arm now

    I don't follow that - as long as nothing fouls anything else, isn't that enough? Why is there a need for an extra 5mm between the cup of the bottom bracket and the crank arm?

    After a lot more puzzling and searching, I think I am able to answer my own questions: BC1.37 x 24 is just the specification of the thread, and most 68mm bottom brackets conform to that.

    So I should be looking for a 103mm spindle width bottom bracket, and it seems simple enough.

    I have a bike with a Shimano bottom bracket fitted; its label says:

    BB-UN54 [part number]
    68 [bottom bracket shell width]
    BC1.37 x 24[what do these mean?]
    LL113 [113 is the total spindle length, what does LL mean?]

    It's just about OK on the bike, but the chainwheels (a Sunrace R90 Road Double Chainwheel - 50/34T FCR96) are further out than is ideal. They could easily come in 5-8 mm. So, I'd like to find a bottom bracket that fits better.

    What specifications should I be looking for?

    I guess I can say goodbye to the paintwork under the Tubus clamps. At least they look like they won't be moving much.

    And that AR-1 should be exactly what I need... are racks like that simply not made any more?

    I could have sworn that I'd asked about this here already, but I can't find any sign of it, so here it is.

    I have an old Dawes Galaxy. It doesn't have seat stay bosses to secure a pannier rack. The best option seems to be some sort of bracket that will use the rear brake bolt, and provide mounting points for a rack.

    I have a rack already - it's just the bracket I need (otherwise I'll need to use P-clips I think). I previously made one; it broke.

    I can't find such a bracket anywhere. Does anyone actually make such things? What are they called?

    (A seatpost clamp with rack mount points won't work on this bike, so that's not an option.)

    Hey, I'll gladly take the saddle if you're willing to post to the Netherlands

    I am travelling to Leiden from the UK on the 20th June - if that solves a problem, I don't mind being a saddle courier.

    For a triple chainset, in case that makes any difference, and ISO pedal threads (older ones had French threads).
