I am considering buying a Surly Steamroller (fixed gear) complete bike, which uses Surly brand hubs. I posted this in the SS&FG forum, and one of the replies stated that there were problems with these hubs getting out of adjustment and the bearings wearing prematurely. I've read some previous postings and have seen mixed opinions on this issue, so I'm not quite sure what to think. Apparently, they are adjustable and during installation with a solid axle and track nuts, the axle can rotate and the bearing adjustment can change. I know that traditional adjustable cup and cone bearing hubs use a keyed lock washer and a lock nut that when properly tightened against the cone after adjustment will prevent movement alone the axle that would change the adjustment. So, do the Surly's lack this or is there some other reason for them to get out of adjustment. Would I have to carry a cone wrench with me when riding to prevent this problem from occuring if I had to remove the wheel on the road to fix a flat? I don't want to have to constantly adjust the hubs on my bike, and don't want to buy a different set of wheels for this bike, so if indeed the Surly hubs are a PITA, that's pretty much a deal breaker on buying the complete bike. Thanks in advance for your help.
