Those of you who have been into cycling for 20 years or more may remember (not fondly) the era of the Shimano Bio-pace chainrings. If you're lucky enough to have never heard of them than I'll explain. Basically they were oval chainrings. The idea being that they 'smoothed out' your pedalling
to give a smoother 'power stroke'.
It was at best an odd idea that was thrust upon cyclists for a number of years with ever stranger shaped chainrings from copy cat 'budget' companies. Bio tech, Oval tech, Egg tech and even Square tech were fitted as standard to hundreds of thousands of poor unsuspecting bikes.
Personally I always thought it felt like riding with a rubber chain (ie. horrendous). I always felt pity for the poor pros riding the system to fulfil their sponsorship commitments.
Anyway, almost as quickly as it appeared it thankfully vanished. Gone the way of A.B.S. brakes and suspension cranks (they really did exist and really were as bad as you'd imagine) or so I'd thought.
I recently came across a couple of articles about the 'latest development in chainring technology' Rotor Bikes Q Rings. Hmmm
, these look strangely familiar and alarmingly oval...
Oh my god, they're back!
And I'm not talking Mickey mouse tat either. This is lovely looking stuff (through gritted teeth) with gorgeous cranks and bottom bracket. Whats more they're being taken seriously, very seriously. The BMC UK RACING pro team are running the system for the 2009 season and they have been raving about it (but then they are sponsored by them).
Perhaps Rotor have succeeded where the big S failed but I'd be amazed. Personally I wouldn't touch it with a barge pole but I'd like to be convinced.
Only time will tell if we're all going to be pedalling about on eggy rings in 18 months time. I just hope that it's not forced on us this time.
