Damaged Bottom Bracket

I normally test pedal my bike before preparing to leave.   And, I noticed that my 29er was not smooth to pedal.

When I checked, I thought something's wrong with the bottom bracket, which  is a Shimano SM-BB70 and part of the XT crankset I bought second hand and installed more than two years ago.  It hasn't been serviced yet since then.

Meantime, I parked my 29er back and used my 69er for my ride.  That's the beauty of having more than one bike.

When I returned home, I removed the damaged BB and replaced it with my spare BB.

I dismantled it and tried to fix it but unsuccessful.   The bearings has seized up already.

Thus, I need to buy another one as spare.

Saddle puzzle

Last September 18, I was on my way to Timberland Heights when I had a minor fall. As a result, the saddle was disengaged from its rails. I tried to replace it; but, I couldn't despite several attempts. So, what I did was I went to a biking friend who lives nearby and ask for his assistance. Fortunately, he has a spare saddle, which he lent to me.

At home, I tried to analyze the situation. The saddle was disengaged without deforming the saddle nor bending the rails. Therefore, it could be replaced.


However, my first try was a failure and so my subsequent attempts. I tried all tricks but to no avail. I brought the saddle to a local bike shop; but, the mechanic there couldn't repair it too.

I followed the advices of my online biking friends - to do the bending technique. This did the trick.

Fixing flat tire myself

BikePot (my first bike) was flat again. This time it's the front tire. I tried first to pump it; but, it's not fully inflating.

Last week, it's the rear tire that's flat. And, I had it replaced at the store where I bought it.

Okay! This time, I'll fix it myself. I now have the gadgets and the knowledge (through the internet) to change the tube. I already bought a spare tube, a tire lever, and a portable pump.

First, I reviewed some instructional videos from the internet. Very confident that I could do it myself, I began the procedure.
Not a single drop of perspiration, I finished the job in no time. The job's as easy as falling off a log.
