Morning all,
Hope you are all well?
Having cleaned my bike recently, I noticed that the back wheel rim has little cracks in it around where the spokes are. Some have little splits radiating out from either side of the spoke, and some have little splits around the spokes. To the untrained eye, it appears as if the spokes are pulling through from the rim. I've attached the best couple of pictures I have - but my camera doesn't really like doing closeups.
The bike is a 2010 Marin San Anselmo Deore (http://www.marin.co.uk/2010/bikepage.php?ModNo=10AN) with WTB Dual Duty, Double Wall, 36 Hole with CNC Side Walls rims. She's about two years old and has done 3200 miles, mainly commuting on roads or cyclepaths (no offroading). I am reasonably heavy at about 17.5st, and do carry panniers to work.
What I want to know is
- is this normal wear? Does everyone's bike have it and I've only just noticed it?
- is this a sign that a new back wheel is required? (disappointing if so, given age/distance).
- is it safe to use, or should I immediately stop?
- am I unnecessarily concerned? It has just come out of the LBS for something else and they didn't mention it.
Thanks,
MG
