Shimano RS-80 damage - serious?
Posted: Mon Feb 04, 2013 8:03 pm
I just discovered a problem with my rear wheel (RS80-C24) which caused a flat yesterday. The flat was caused by the rim tape giving way over one of the spoke holes which allowed the tube to balloon into the hole.
Upon examination, there is small ridge at the edge of the hole, I can't quite see whether it's just the bunched up rim tape or something in the aluminium of the rim - I think it's just the rim tape though.
Then looking at the outside of the wheel there's a small gash in the carbon reinforcing close to the same spoke.
A couple of weeks ago I had a blowout in this wheel at speed when I hit something on the road - a bit of glass or metal or something, never found it. The gash was in the side of the tyre, not sure if it was at this spot but it makes sense. I noticed that there is some paint scraped off the frame underneath the brake consistent with something flying around with the wheel. Maybe this is a result of the same incident.
The scratch doesn't seem to go deep and the wheel is true. This spoke does seem to have a little less tension when plucked. I wonder whether the gash and the hole in the tape are linked?
Advice is welcome, should I be worried? My inclination is to put a dab of epoxy on the gash and replace the rim tape, assuming that the bump isn't in the aluminium.
Thanks,
Steve
