So I've got this pristine (barely even 100 miles) Mongoose Tyax Pro (2008 model I think) from my dad. I probably put an excess of 6,000 miles on an identical one I had. I rode it to high school every day (EVEN in the pouring rain, the 30 degree weather and the hot hot heat), to my girlfriend's house, to the local hang out spots, to downtown. You name it, I rode my bike there.
Eventually, some parts started to develop fatigue. I sold it and liberated this pristine one from my dad.
In my younger and lazier days, I would let stuff slide and disregard small problems until they turned into big problems, but a recurring issue has developed between these two, identical bikes.
After a few months of serious riding, my original bike developed a very annoying bottom bracket ticking. It kinda got worse over time, but it never hindered the performance of the bike. It started out as 1 tick per revolution, then 2, then 2 and a half ticks, then 3, then 4, and at that point I stopped counting or caring.
Before you say anything, I took it back to where it was bought numerous times. Even though it was sold with a promise of "tune-ups for the life of the bike", they didn't want to honor this serious sounding problem so early in the bike's life.
The noise wouldn't happen unless there was weight on the pedals. So, of course, when you put the bike up on a mount to test it, it was squeaky clean (no pun intended).
I, nor my uncle, ever wanted to go around messing with taking the bottom bracket apart. My uncle has two Masters degrees in mechanical and electrical engineering, in addition to riding/fixing bikes for 20 years, and he still opted out of a wonderful opportunity to total a great bike by taking apart the bottom bracket.
Sorry for the long post, but I was curious if anyone was familiar with this issue? The other bike (with almost zero use) already has the ticking issue. On the old bike, I tried tightening the BB a little bit, loosening it a little bit, but it didn't seem to make a difference.
thanks for the help guys!
p.s. When taking the new bike out for a spin, the front lock-out didn't seem to work. This disappoints me greatly because I loved the lock-out on my old bike, and the front shocks are especially mushy. Is this a blown seal or something?
