:shock: I can't belive this is even up for debate!
The case for the prosecution...
1. They look awful
2. They f**k your knees if your cadence is fairly high
3. They remind me of the 200GS groupset (my only experience of them)
4. They are retro in the same way whit dog poo is retro, i.e. it reminds you of times gone by but you wouldn't put it on your bike!
The new rotor rings are kinda bio pacey but have the cam in a different position which was were biopace fell down. Bobby Julich use them for time trialling. Never used them myself but remember seeing them and thinking they were cool( well the principle anyway) :roll:
