I purchased a Specialized Pitch 2017 basic model 1 1/2 weeks ago.
When I'm in gear 13 (most comfortable gear to ride on), and put extra pressure on the ride (standing up, pedal faster, harder) it feels like the rear gears have slipped a gear.
It makes the customary 'click' but I've checked both before and after and the chain is on the same sprocket. I have even turned it upside down but cant replicate it under pressure.
I know there are bedding in issues, but this shouldn't be the case under 5-6 weeks or 100 miles (160 km).
Would anyone know what the issue is? I have it booked in for a service next Saturday so will keep an eye on it this weekend and next week. Just hoping for a quick fix before I have to take it back to the shop.
