    Not a fan of this technique as I believe it encourages too much tension on the chain.

    If you ride a bike with a singlespeed drivetrain you really should learn to tension the chain properly, it's one of the few skills you need to keep your bike running good, it's a lot easier to master than say indexing gears and it's arguably more related to your safety than the likes of gear indexing, especially if you ride without a (rear) brake.

    I would encourage you to use your hand between the tyre and seatube to set the tension initially and to then 'walk'* the wheel backwards or forwards to fine tune the tension.

    • loosen the nut on one side and use your free hand to manipulate the wheel side to side at the point where it passes the chainstays. Repeat with other side nut if neccesary. Moving the wheel towards the drive side chainstays will increase tension, towards non drive side will reduce it.

    To be brutally honest though, if chain tensioning is beyond you I'd suggest you see if there's a mechanic or just a more mechanically able mate that can be persuaded (beer, Jaffa cakes, etc) to give you some advice/lessons.

    I presume by the fact that you're using a bung over a star nut that your steerer is carbon. In which case running the set up you have drawn might be invalidating your warranty. A lot of manufacturers specify that a (minimum) 5mm spacer must be run above the stem to avoid the stem clamping too near the end if the steerer and causing damage.

    A bit of an anti climax eh. Like most modern politics IMO.

    ^This,

    If you're doing that, looking at mixte/dropped toptube frame will probably open up more options to you, in terms of being able to get a slightly larger frame but still have standover clearance.

    When I was building my gf a bike I was looking for a similar sized road frame and finding nothing worthwhile, I ended up getting her a ladies Trek frame that I think is around 50cm. The seat is slammed but there's plenty standover and the length is better.

    Are the parts that hold the seat rails bent? More likely the bottom would bent than the top but you never know.

    If so, find a similar/identical part from an ordinary post and swap.

    ^ I did a project along similar lines a few years ago,

    The track ones don't seem to like to stay straight for very long, that said though they haven't cracked like a lot of the other brand tandems I've seen have.

    I have a couple of the Alpkit drybags with the loops and I've been meaning to look at attaching them to my Outpost rack somehow. I figured it'd be handy to have a lighter alternative to my Ortlieb panniers.
