請教2010款 Lightweight Obermayer III Tubular & Standard III Tubular 的差異性只有重量嗎?
Obermayer III Tubular :
Rear wheel equipped with DT Swiss 190 Ceramic hubs
Front wheel equipped with Lightweight hubs
Systems: Shimano (SRAM compatible) or Campagnolo 9/10 Speed
Front wheel spoke count: 12/16/20
Rear wheel spoke count: 20
Weight per set: 960/975/990g
Max rider weight: 80kg/90kg/100kg
Standard III Tubular :
Rear wheel equipped with DT Swiss 240s hubs
Front wheel equipped with Lightweight hubs
Systems: Shimano (SRAM compatible) or Campagnolo 9/10 Speed
Front wheel spoke count: 16/20
Rear wheel spoke count: 20/24 (Sprint Version only)
Weight per set:
16 Front / 20 Rear 1015g
16 Front / 24 Rear 1075g
20 Front / 20 Rear 1030g
20 Front / 24 Rear 1090g
Max rider weight:
16 spoke 100kg
20 spoke 120kg
24 spoke >120kg
看出來了嗎?
1.HUBS的差異,前輪以相同的spoke count都選擇16,HUBS的重量相差為40g.
2.以數學加減可以得到spoke每一條的重量3.75g.
所以綜觀上述的比較可以發現190的hubs較240的hubs貴上約40k,以CP值來看要如何選擇?
