My old disco twin tandem.
The original suntour se brakes were poor, and I tried V-brakes to see if these would be more effective and easier to maintain. They are, but not the revelation I'd hoped for. The original arai drum brake was warped and not very effective, so it came off.
I fancied trying the mitec hell-bent bars so put these on the bike, but theyre better for a trail bike rather than anything else, they're too wide for the tandem. The twist-shifters work very well though, and I replaced chains and cassette with a view to sell it. I'm still half inclined to sell it
