I thought this weird. I've been riding my bike for past 2 years (~4,500 miles); always in temps between 60 to 90+ without a flaw in the shifting.

This weekend I took my bike up into the Sierra's and rode in 50 degree temps. The rear shifted like crap! Like the cable was binding, sticky, or very very stiff. So, what's up with that?

Any recommendations to smooth it (Ultegra 9sp) out like it shifts in warmer temps? I know. I could lube it but why did it do it in the first place? Doesn't the factory lube accommodate temps lower than 50 degrees?

My girlfriend's bike has the same derailleur. Her's didn't change like mine in same conditions.

Oh. I got home from the trip today, temps in 70's. Rode the bike. It shifted normal again. Wierd.
