swapped the seat clamp on my mirraco for a profile slim jim, but despite having loads of allen keys none of them seem to fit
4mm is too small, 5mm too big so thinking it must be a weird imperial size? (helpful)
anyone know what size(s) this might be?
even better if anyone going to boardroom on saturday has one please can you bring it with you so I can tighten it up?
cheers
