well i removed the chainset and BB immediately, it’s too big a gear for off-road, to some fakinger on ebay and for the same money replaced it with a Campag compact chainset and BB that’s still going strong, the rear wheel bearings gave up after 5 winter off-road rides and had to be regularly be repacked with grease and have a couple of bearing changes before i swapped it out for a Goldtec hubbed wheel (which has been excellent) the front wheel faired a little better but still needed regular looking at, the headset bearings (real basic unsealed caged bearings) didn’t like it off-road too much so they were replaced with a Hope integrated unit
but i did treat it badly, proper 3hr+ off-road rides through a very puddly winter, a task some of its parts weren’t designed for
