Went shopping for salad and shredded cheese, and saw this. Colostrum? Sure doesn't look very appetizing... marketing fail?The Lightning crankset uses 30x42x7 bearings. I learned a technique for measuring the height with vernier calipers - but you can only do it with mechanical calipers, by using the other edge of the calipers and extruding it alongside the height of the bearings, and forming a "T" while watching the pros at work. I also became an expert with the language... "sa zhup si zhup zi luck gao"... nice. By the time I reached the 3rd distributor, I sounded like a pro myself... (I even knew that measuring technique before the employee at the counter was being taught by a senior staff.)
Silicon nitride bearings cost US$98 per pair. Hybrid ceramic bearings cost US$48 per pair. I walked all over the country zzz... The bearing distributors are all located at obscure locations (e.g. red light district). Unfortunately, they only sell steel bearings.Looks like I can't beat the pricing game, and wasted my time. ):
The bearing cups weigh 89.1g including the bearings themselves. The crankarms + BB - cups are actually pretty light at ~343g, almost like Claviculas. I noticed a few tuning options:
- The bearing cups have indentations for the wrench when you're removing them - doesn't seem necessary, you can pry them apart with a screwdriver anyway, just that it's easy to crack the bearing seals. But you're probably going to replace the entire bearing set when you need to remove them anyway. So I think I can grind some material off the cups.
- The bearings themselves, as I'm experimenting now.
- There is a small bolt on the non-driveside crankarm.
- The crank bolt?
Anyway, for the locals, the point is, get your bearings from Yew Kee Bearing Company (Geylang) or Kian Ho Bearings (Jalan Besar). Great service attitude from both, although they didn't have the size I wanted.
