Rim wear indicator

Postby kelmackie 1972 » Sun Nov 18, 2012 20:18 pm

Was out riding with a group of friends today when one of them pointed out that I had black line on my fulcrum 7 rim where the brake blocks meet.He said that my rims were worn and need replacing ,Ive tried looking on the fulcrum website and I am none the wiser,I would appreciate any info from someone more experienced than me as Ive not come across this before thank you in advance .

My Shimano wheels have a small dimple machined into each brake track on the opposite side of the wheel from the valve hole. They are really quite tiny, and difficult to see when the rims are dirty. When they are worn away it means the rim has reached it's minimum recommended thickness.

Current Fulcrum info suggests that the racing 7's had something similar from 2011?

My bike is a 2009 ridley orion with the original wheels still on it ,only started thrashing the miles on it after march 2010 though .There are no dimples on the rims as far I can see though I have seen them on shimano wheels .It is a groove around 1to 2 mm thick and about a a mil in depth which seems to be black and runs around the diameter of the rim it could be part of the rim build or am I just being dumb ,probably take them down my LBS at the weekend.

some rims have a wear indicator and you are fine until you can not see the line.

a picture would be good to check.

+1 Sounds like you are describing the wear indicator. No need to worry until you've worn the rim down so the groove is no longer visible

maybe you cant see the dimple because... same goes for the tyre's... some have it, not all. it's a guide. You take the risk, make the call...
