I was just at my LBS, and the shop mechanic was saying the roller bearings used in Shamino hubs tend to take side load stress better than cartridge bearings used in more expensive hubs.

What are your thoughts on this???

Your LBS is 100% correct.
They do take side loads better and therefore will last longer if serviced regularly ie every 6 months.
If fact they're also very well sealed. recently had mine (XTR) opened after 2 yrs of abuse, probably done about 7000km on them already and the grease was still clean. The Mechanic just closed them right up again and said "See you in 6 months"

Absolutely the best hubs are cup and cone, just ask Shimano & Campagnolo.

While that is probably correct, I've found with Shimano hubs that over time the cup and cones the bearings ride in get pitted and scored. In the case of the cups this means you need to replace the whole hub which means a wheel rebuild. Since I hate rebuilding wheels I'll stick with my SRAM hubs which use easily replaced, inexpensive, 6000 series cartridge bearings.

that's why they still make it that way.

Ball bearings, not roller bearings.

Yup, cup and cone loose ball bearings can be very good - if you take care of them.

I like cartridge bearings for the ease of replacement and the fact that a trashed bearing does not mean a trashed hub.

yup... what the others said.

Or you can get an angular bearing in the same size... but it would be an act of god find one. There are some, but I ignore if someone had explored the use of a different bearing for hubs.
