基於女王準備上公路車的緣故, 以及她根本就是沒有什麼腳力和速度可言,
所以我想買一對輕一點的輪組, 讓她在一般平路情況下可騎得輕鬆點, 也希望她可以爬到一點坡, 可讓我倆能一起享受騎車樂趣
這些是我考慮中的選擇
1. Shimano Dura Ace 9000 C24 clincher
2. Easton EA90 SLX clincher 2013
3. Mavic R-SYS clincher 2013
4. Campagnolo Zonda clincher 2013
各位有何建議呢?謝謝!!
不建議打超過125磅..
不懂打高壓的目的何在?
我管胎也不會打到140磅..
zipp原廠甚至警告管胎打至170磅.極可能於遇到撞擊坑洞時傷到框..
Recommended tire pressures by rider weight
As far as tire pressure goes, I suggest a maximum of 140 psi and a minimum of 120 psi.
What we found through testing is that anything over 140 creates more rolling resistance,
but let’s say someone puts 170 psi in a tire. A tire at 170 psi pressure could induce impact
damage due to the amount of pressure that is in the tire while compressed against the rim.
The same can be said for running anything lower than 120 psi which decreases the protection
the rim gets from a properly inflated tire.
概括來說對於一般的騎乘者,胎壓的建議,我們建議最高 140 psi ~ 最低 120 psi,這個壓力數值來自於測試當中,超過 140 psi 時會增加滾動的阻力,但如果將胎壓打到 170 psi 這將會增加撞擊毀損的風險,大大的增加輪胎對於輪圈邊緣的壓力。同樣的來說,騎乘時胎壓如果不足 120 psi 將會減低對輪圈的保護.
open碳纖框我還有看過爆框的
非zipp,哪牌就不說了,車主用schawlbe的open胎打到140,
遇坑洞,兩輪內胎都爆,隔週騎,休息時框突然爆開,所幸不是在高速行駛中~
