Alphalab Kommuter

i've always wanted a tight handling roadbike with short wheelbase. so here it is.|||| but, to be honest, it's actually millimeters away from failing to become a roadbike.. the wheel QR clamp is on the edge of the trackend.. but i think it's still safe to clamp it there (see picture).. probably because that the chainstay is too short and the seatstay bridge is too low for a road bike.. if i move the wheel a bit to the front, it will graze two things: the FD Clamp and the rear brake.. i've tested with my brother's rear track wheel (with extra 5mm spacers on each sides), it is super tight!.. conclusion: Alphalabcrew urgently needs to improve their skills and experience on multigeared bikes.. i've heard that their single-speeds have no issues at all.. other than that, they're great to work with ..but be sure not to copy this geometry.. it's a failed one

1.90kg untuk hiten sebenernya tidak terlalu berat

tetapi minusnya adalah bb-sway kerasa.. untuk roabike, disaat sprint (over the saddle), kerasa bgt energi yang dikeluarin nggak semaksimal kalau pakai Alu/Carbon
tapi cukup layak untuk digunakan harian

yang disayangkan adalah, chainstay terlalu pendek, sehingga jarak untuk ngeclamp QR sangat sempit..
maju 3mm, kena seat tube
mundur 3mm, udah gak bisa di clamp lagi

pada akhirnya, sepeda ini digarasikan dalam waktu kurang dari 2 bulan
