獲贈Trek Lexa S Compact 2014後,
https://www.ptt.cc/bbs/bicycle/M.1518266399.A.11E.html
太座開始嘗試轉換到公路車了,為了讓太座比較容易應對桃園這裡的丘陵區與
山路,把原廠不知名輪組換成了先前自己用的 RUBAR SHADOW ULTRALIGHT輪組,
飛輪也換成了 11-32。這個升級還蠻有效的,車重由10 kg 一下子變成8.8kg,
原廠輪組真的非常重啊(輪圈+耐外胎+11-28飛輪+外拆 = 3.3 kg)。
這樣的調整讓太座第二次騎乘時,面對爬坡時也不會覺得太辛苦,直說比小折
(也是CT盤/11-32飛輪)輕鬆許多,騎起來也非常愉快,覺得太座應可以無痛轉
換了.....
然後問題出在下坡.....
太座的手不大,握上把時無法有效掌握Sora煞變把,煞車拉不住....緊張得大呼
小叫,甚至停下來甩手,擦手汗....最後是教太座使用下把...慢慢滑下山。
回到家,太座手很酸...用上了酸痛貼布,還把護腕也帶上了....
下午幫太座檢視單車,發現太座的煞車真的很緊,不好拉,手感差105/挖地瓜非
常多,105煞車是輕輕點一下就有感覺,太座的煞車真的需要很用力,即使握下把
也是蠻辛苦的....
查了一下,這部 Trek 配的煞車夾器是不知名品牌,原廠只說它是鋁合金夾器

要請問各位車友,如果要改善太座的煞車,怎麼做最有效?
1. 換掉煞車塊,有推薦的品牌嗎?
2. 換掉煞車塊/煞車夾具:夾具直接換成105?或是有推薦的品牌?
3. 煞變把/夾具有沒有可以調整的地方,或是重新走線?讓它變得比較輕一點?
感謝各位的建議....
