  • I rode an audax last weekend with a 57yo 12 and 24hr tester. He taught me a lot about pacing and HR zones and had clearly put in loads of miles over winter as he was incredibly strong. Pretty sure we rode the second half faster than the first. Literally could have kept going all day. CSB.

    Anyway, I find myself here again looking for some help. I have some clip on 3t aerobars with an OD of 22.2mm.
    I'm about to pull the plug on a pair of those Raceware aero bar end plugs that tester linked to a few weeks back but struggling to find what the internal diameter is. My digital callipers are fucked so I can't measure them. Am I likely to need the 19.2mm or the 20.2mm ones? Many thanks

    You can pick between 19 and 20 with a rule, Abom79 reckons you can reliably get within 0.010" which is 0.25mm in the new money. Buy 5 for 30p each, punt out the surplus to other LFGSS users at 50p and profit :)
