Someone must have swapped the rear wheel since the bike was built as there's a sticker saying "Equipped with Rohloff".
Not necessarily. My frameset came with that sticker. I bought a Rohloff wheel separately, but could have bought a Shimano hub instead. If I had been a bit younger when I bought it I would probably fitted a Shimano 8, but not an 11 as I didn't trust the first version of the Alfine 11.
How many speeds has the Alfine hub, 8 or 11? The latter is worth more but isn't as robust as a Rohloff hub and has a smaller gearing range than the Rohloff so is less suitable for touring anywhere with hills.
The original poster says 8-speed. I like the Shimano 8-speeds, and have them on several family bikes. But the resale value is obviously
much lower than a Rohloff, which seems to keep a high second-hand price.
And in 2026 I doubt that anyone would buy a bike with an 8-speed hub with a range of "only" about 307% for touring in hilly areas.
This is mainly because expectations have changed, my state of the art 15-speed tourer in 1977 had a gear range of 343%, only a little wider than the Shimano 8 hub gear. My fellow riders in 1977 considered it to be overkill, most of them had the popular 40/50 double chainring setup, with an overall range of about 250%. My "overkill" setup did, however, enable me to cycle up Hardknott pass in the English Lake District, the steepest bit on that hill is supposed to be about 30%.
