i just rode the aurem in front of my house to bed in the disc brakes and make sure everything works. it rides AMAZING

感謝KEVIN的詳盡解釋, 再請問若是以AUREM與MANUS來比較, 這兩款是不是一般所稱的長版與短版車架的差別? 基本上在這兩款之間做選擇的時候是不是以體型大小為原則, 或是以技術能力為選車的標準?

that is a really good question. the manus shares very close geometry to the silver sky i tried out. i dont think it matters much how tall you are. manus and aurem are for very different styles of riding. the manus is more for fast speed bunnyhop moves. with the aurem, you can do moves that is usually harder on a mod bike, such as front wheel moves.

to sum it up, the aurem is a bit like a 26" bike with little wheels. the manus is more like your traditional 20" bike

usually, brands like echo simply increase the wheelbase on their frames and call it a long frame. the reason the aurem has a slightly lower bottom bracket than the manus is because with the logner wheel base, you get more leverage, making the bike feel lighter on back wheel. if it was any higher at that length, it might become too sensitive to ride.

再問一個假設性的問題.

如果有兩台車實際上的規格都相同, 只是頭管角度不一樣, 而因為一台用較長的龍頭另一台用較短的龍頭使得站立在兩台車上的相對位置還是相同.

請問這兩台騎起來會有差異嗎?

im not sure what you mean, so we will compare it like this :)

case 1 :

frame 1 :
1020, +75, 350, 71.5
frame2 :
1020 +75, 350, 72

frame2 will feel slightly longer, because the reach will be longer due to the headangle. on the back wheel, frame2 will feel lighter (only VEEEERY tiny bit), because the wheel is closed to you. frame1 will feel a little bit more stable on both wheels, because the bar doesn't feel like it is too easy to turn.

obviously, having a slacker headangle only offers more stability to a point. for example if you had a head angle of 60 degrees, that would be stupid and way too slack:P


case 2 :

frame 1 :
1010, +75, 350, 72
frame 2 :
1020, +75, 350, 71.5
(lets say for theory's sake, that the 2 frames have the same reach)

the length of the bikes should feel very similar. frame 2 will be a little bit more table, and frame 1 will feel a little bit lighter on the back tire.

frame 2 will have a little bit more reach, so gaps to front wheel and moves that involve bumping the front wheel will be a little bit less scary.



of course there are many other factors to how the bike rides. but i think thats generally pretty correct.

感謝, 上文中 CASE 2 是長短版的問題, 我問的是CASE 1 的狀況.

那就是說車軸長相同的狀況下, 頭管角度大(如72度)會與頭碗角度小(如71.5度)時車架的長度成反比, 頭碗角度小的車會比較穩定, 頭碗角度大的車比較靈活, 不過依攀岩車的需要這些角度都只會有很小的差異.
