Cracked Bicycle Rims… and Derailleur… and Chain

Update

Let’s see.  I think I’m replacing my Cannondale R700 a piece at a time…  It was my rear rim in 2015, my front derailleur in 2018, and now in 2019, I snapped my chain while riding up a steep hill.   Attempting to walk 10 miles back home with my chainless bike would have taken quite a while.  Fortunately, I had my “training director” (my wife, Missy) drive out to pick me up along with my disabled bicycle.

I was riding up a hill at Englewood Reserve, and after shifting into what I thought was 10th gear, I pondered, “Wow, I must be getting old. This is more difficult than I remember”.  That’s when I looked down at my Shimano 105 front derailleur and discovered a broken spring.  I was actually in 20th gear going up the hill.

Oh well, another part to replace on my Cannondale (this model has 3 sprockets up front and 9 in back).  I suppose the one consolation is that I’m still a spry young man on my bike.

I’ve been noted to be pretty harsh on mechanical devices that I own (I used to break the frames of my motorcycles during my motocross days), but I never expected to have multiple cracks in the rear rim on my Cannondale bicycle.    These Mavic rims are not cheapies, but in the second photo below you can see one of six cracks in the holes for the spokes.

Fortunately, my trusty bicycle service center at Troy Family Bike Shop got me fixed up with new rims and a tuneup.
