Not enough to be noticeable to the average rider reading the forum but you are changing the overall wheelbase and moving the weight balance of the rider with respect the rear wheel a fractional amount when the rear is adjusted at either end of the adjustment range. The sprocket sizes determines the wear rate with the two sprocket system such that the smaller sprockets teeth make more chain contact per tooth than a tooth on the larger sprocket. Hence if you had a perfect three times number of teeth difference the smaller number of teeth sprocket wears three times faster than the larger sprocket. With new chains you normally want new sprockets installed at the same time as worn sprockets and new chains are going to be a bad mix wearing the new chain faster. I had about ten miles on the bike when I changed the chain and rear sprocket so I kept the small oem sprocket on the bike. Other than running a new chain on worn sprockets, the conditions where a chain is ridden in has more of an impact on wear, dirt and sand being more wearing to a chain than street riding. Keeping it cleaned and lubed will be enough for most riders to get good life while keeping an eye on sprocket wear. Everyone has their favorite chain method for care so I’m not recommending any products but for the curious I have no lube right now as I’ve checked all my local physical stores and none have the one I use, so I’ll put an order on Amazon for mine as it’s there.
