This is probably one for a LBS but thought I'd ask in here first to have a better idea whats going on & to understand how best to explain to the LBS (if its not something I can sort myself)...
So I have a Specialized Diverge with Tiagra gears. Sometimes when I change from the small cog up to the big cog on the front BB, the pedals feels like they're slipping/clunking for a few metres until it catches and changes gears. It doesn't always happen - changes seems a little better when on flats/downhill and if I freewheel a bit during changing gears. I suspect there's something going on in the rear derailleur but not sure what...
Or is this normal when shifting from small to big? I took my bike to the (not so local) LBS where I bought the bike for the bike's 6 weeks maintenance and mentioned it to them but although it was a little better afterwards, its still happening. I'm a little reluctant to go there again due to their location so would likely need to take it to a properly-local LBS if its an issue I can't resolve myself. (FWIW, they do have another more convenient store, but that location doesn't have a workshop as far as I know).
Thanks in advance for any thoughts!
