bike to work day

Hopefully the first of many more. The only problem (apart from the usual one of drivers being on my road and slowing me down) is that the chain slips on the fifth cog. It’s probably a wear issueas that bog was part of my old favourite ratio. The new chain hasn’t worn down in sympathy to fit the hook shape. So i’m working with the ratios one higher and one lower than i’m used to, so my legs are spinning wildly or grinding harder than they’d prefer.
I’ll get used to it, the important thing is that i’m back on my bike. When i start working from home i’ll have to make up random reasons to go for rides.
