螺絲都成千銀一粒
Tit bolts don't sell for HK$1,000 a piece, they usually sell for between US$4.00 to $$8.00 each depend on size.
The cost to tune the bolts for a normal bike should not be much more than US$250, you save roughly around 120 to 160 gram per bike. Make sure you don't use them in load bearing areas.
Tit bolt is about 60% weight of a steel bolt, aluminium alloy bolt is only 1/3 of steel bolt.
Use it wisely, don't try to save 3 oz and end up breaking your neck. |
