Can I upgrade a Norco Yorkville for a 260 pound rider plus cargo? Hello I have a 2017 Norco Yorkville. I was breaking rear spokes so bought a better rim with tougher spokes. Now my suspension seat post is wobbling.
What else can I upgrade on the bike for a 300 pound plus load? I could trade up to the next level bike but prefer to stay with this one.



Aluminium 7005 frame, 21 speed (3x7) with rim-brakes and suspension seat post.  https://www.norco.com/bikes/city/hybrids/yorkville/yorkville/   With a MSRP of $369 USD its above a BSO, but still an entry-level model.
One solution for getting the load off the bike is to tow it in a trailer.

This would be overkill if you're carting around a waterbottle and a pocket of keys, but if you're loading the bike with 20+ kilos (44+ pounds) of stuff then moving it to its own axle could help.

Downside, trailers aren't cheap, and they will slow you down while riding.
