Shimano Deore Hollowtech chainset (Octalink) FC-M510 and bottom bracket - birthday present!

Category : cycling

Chi looked over my bike at Sungei Kadut coffee shop this morning, well after midnight, during our last bicycle ride for 2005. Next thing I knew, he and Cat decided to present me a new chainset and bottom bracket for my birthday!

So this morning, despite hitting the sack at 3.30am, he and I were off to Hup Leong at Chin Swee Road. This is where my cycling kakis originally sussed out the GT Avalanche 1.0 presented to me as an early birthday present, just in time for my first round-island ride on 22 Sep 2002.

At Hup Leong, Gilbert pronounced my 9-month-old chain due for replacement. I have not perfected the technique of shifting gears gradually to maintain minimum chain tension which wears it down. But also, the very rapid and extreme gear shifts needed during urban riding rides are akin to races that cause lots of wear and tear.

So after some finger wagging, and the reminder that a stitch in time saves nine, the chain was scheduled for change as well.

When we came back from lunch, a Shimano Deore Hollowtech chainset (Octalink) (I think its the FC-M510) had been installed, along with a new Shimano chain and bottom bracket.

Trying it out up the slope to Pearl's Hill City Park nearby and I could surprisingly feel the difference. Chi explained that the ramps in the sprockets help with gear shifts and added something about a Shimano patent with regards to chainset and chain that has it all working very smoothly but I'll have to ask him about that again. Cat later explained she had been talking about this for the past two years but it had all fallen on deaf ears!

We salvaged the Truvati pedal shafts and Modus bottom bracket and I went home a happy camper! Very interested to see how it affects my next half-day ride. Thanks Chi and Cat!
