RD freezing up at near freezing conditions
Has anybody else had this problem?
My Warbird has a Shimano GRX 600 RD and internal cable routing. Twice in the last few weeks I've been riding it at icy conditions near freezing, and the shifting froze, giving me a two speed (FD worked OK). I've had this problem occasionally with the other bike I use for winter, but that has external cable routing and I've been able to see the ice on the cable and remove it. With the Warbird/GRX, I have no clue where the freezing is happening. On a cable? The spring or someplace else in the mech? I look at it, move the parts around, and it has no effect. But once the bike is brought back inside, the ice melts and RD is fine.
The Warbird isn't my only winter bike option. I thought that it would be better for this because of the internal cable, but in this respect, it seems to be worse. If this keeps happening, I just won't use it unless temps are above or well below freezing.
