Noisy spin

I had an easy spin workout today, as I get back on schedule. The problem was a clunk that is happening in the front hub. It's like the cranks are slipping just a bit, almost every rotation. It's been a year, so an overall servicing isn't a bad idea anyway. Now, where to take her to?

The workout was an hour 3/2. I even did some one leg drill. Went for a short run right after, and felt really heavy. Clump, clump, clump around the block. Lots and lots of stretching on the new mat in the workout area downstairs.
