I just bought a Fuji Absolute 4.0 today (it was sort of an impulse buy after a long search and I already regret it). It has Shimano Revoshift friction shifters (on the L, the R/small gears is indexed). I've only ever ridden mountain bikes with index shifting, and I've never worked on a bike myself. Tonight I take the new bike on its first proper ride and on the very first hill, it's ghost shifting. This bike has been ridden less than five miles (plus whatever mileage is on it from people trying it out at the store).
I can't tell if it's a delay from when I shift on the friction shifter (like when you aren't pedaling enough on an index shift bike and it takes a second to sort of "lock in") or if there is something wrong with the bike. It keeps shifting so many times on its own after I haven't done anything else with the shifter that I'm concerned that it's the latter.
I haven't been able to find any information on this problem happening in new mass-produced bikes, only in bikes that are either old, or that someone built themselves and need to tweak. It seems unlikely that anything has worn to the point that this would happen.
Any insight as to why this might be happening on a brand new bike would be really helpful. I would just take it to a shop right away, but the shop where I got it is a bit far from where I live, and I don't want to pay/look like an idiot unless I really need to. Thanks!
