Here's how my non-drive crankarm looked after taking it off today:
As they say.. them innards ain't supposed to be round! Here's the BB, excuse the dirt it fell on the ground shortly before the pic:
Oh, and yes, I'm sure it was rounded off inside..
Removal of it was rather easy with the proper tools. My riding partner and good buddy Oliver was awesome enough to loan his tools, expertise, and front yard for repairs. The BB came out after some encouragement, then I cleaned the inside of the frame with about 2 lbs of Simple Green. I then re-applied lots of lithium grease, then installed the new Shimano Octalink BB.
After that I installed the new crankarms, pedals, and gave it a whirl! After 23 miles yesterday and 31.5 miles this morning I needed .5 miles to hit my 1,000 mark for the year. I'm happy to say that pedaling around Oliver's neighborhood on a newly improved Hardrock, I passed by the 1k mark for the year! The bike probably has about 2,500 miles on it, but still rides like a champ. Here's a shot of the new crankset, installed and working great:
And finally, my noble steed. Looking forward to many more years of service from it, even if the mileage isn't so high after the purchase of the mileage king of a LHT:
