I gave my chain a clean and re-grease over the weekend, and since then I've found the drivetrain has been feeling really stiff - as if I'd changed up to a bigger gear ratio. The really odd thing is that it isn't constant, I can ride into work and it feels really bad and then ride home and it feels okay, and today it changed over the course of the ride in.
The chain was scrubbed in warm water and fairy liquid, then wiped down, oiled and given a light coat of GT85. I've tried putting a bit more oil on and loosening the bb cup very slightly (it's an old racer with the original cup and cone/cottered setup) but that hasn't made much difference.
Any ideas? My legs are starting to complain about the extra work...
