• Apologies if this has been done to death, I'm at my wits end. Weinemann rim, constant punctures ranging from an inch to 4 inches away from valve hole on spoke side of innertube.
    I've looked for anything sharp, filed anything that could be potentially causing it, put velox tape on + the previous rim tape over the top of that. Made sure I've not pinched the tube when putting it on. Tried different makes of innertube.

    Sometimes I think I've done it. Put the wheel back on the bike. 30mins later pfffffff. It's driving me insane.

    Any thoughts very welcome please

  • DP18? I found that the rim bed was so stupidly narrow that a chunky tyre bead would end up pinching the inner tube.
