  • Yes, they're canti's. Agreed re. the permanent uphill...

    The downtube shifters are friction. I will get this confirmed by a LBS, but I assume that this means that the rear mech will be able to shift the extra few millimetres for the greater number of cogs? Once more, I assume that they don't just push the cogs closer together (?!)

    I may take you up on the aria drum brake. I will seek to use the existing drum though because it's not worn and the drum to frame spacing (for the attachment) is likely to be irregular.

    The spacing is closer on an 8-speed, total dérailleur throw would need to increase by 20% compared with 6-speed but most can handle it.
