Birmingham Bike Polo (Wednesday nights / Sundays - info in the thread)

You can actually buy 'flat' 14mm axles to fit 10mm dropouts. In the middle of the axle - inside the hub - the cross section is a 14mm diameter circle so it fits the centre hole in the bearings*, but at the ends, outside the hub, the cross section is 14mm wide x 10mm high. Curved and threaded at the sides, flat on the top and bottom. They will obviously fit sliding dropouts & track ends. I had to buy one for my Ruption TX5 when I was 13 as I was sick of bending 10mm axles.

*Actually 14mm axles have a 15mm shoulder for the bearings to sit on - the bearings have a 15mm hole.

You can buy axles with flats in them, but they're pretty hard to come by. i found someone selling on in the US, but nowhere else. Its cheaper to try and fix your own too....Moral of the story: read the whole of the ebay listing before buying!
