outsch, an aufa-spokebrake!
i had one but it was quite noisy and a waste of power.
a dymotec 6 is the better choice i think.
.... unfortunately ... I must agree 100%:
1. Yes, it's a real spokebrake
2. Yes, it's very noisy
3. Yes, it's a real waste of power
.... but, for this bicycle, I didn't have other option,
Perhaps you know the dymotec 12 ?
