biking 2010 (6/4/2010)

During my ride at FRIM 14th March encounter un-smoothness at the crank. Yesterday 21th riding at Kota Damansara the still feels the same. Send my bike to my regular bike shop, Heehong and Siang, the boss was not there so Ah Kit had the BB remove and found out the right BB bearing need to be replace. I must said that Ah Kit is a very experienced guy when it comes to bike trouble shooting. You just have to describe to him and he can tell you whats wrong with the bike.

Its been long time I never write about biking and I have not been riding since CNY 2010 till yesterday @ FRIM 14/3/2010.

After the ride went to bike shop and the see the above photo just for sharing. RM55 to reduce 4g for 6 pcs of starbolts for your rotor @ RM55 worth it? Obviously no.

The day after replaced the BB found another sound coming out from the rear wheel. Clean the chain and replace the jockey wheel and still has the sound. Took the rear wheel out and found out that its coming from the hub. Total damaged to replace all the bearing is RM144.
