I know that maybe it's not the bike park thread so maybe it's wrong to put the picture of my bike here, however it's a tandem bike and I would like to share it here..
what I got here is a Polygon Impression AX tandem bike.. Polygon is quite a big bike company in Indonesia..
Its frame is aluminum, I've upgraded almost the whole bike because actually it comes with a low end component, however the bike frame is kinda sweet so it's worth it to upgrade it to a decent touring tandem bike.. the only downside is the frame only have enough screws to attach 2 bottle cage, I'll have to attach an extra bottle cage holder o the saddle.. the OLD is 135mm and it only come with 1 size.. luckily, that size fit me and my girlfriend
feel free to comment..
