I ride with a guy that rides 48's in the front because his feet don't get caught in the spokes as much... I thought that was a good reason for 48h.
Primo SOB hubs are old stock. They have been out of production for several years. Primo now makes N4 front hubs only in 36h.
the Ody store still has Homer front hubs, with 9/16"(14mm?) 48hmine came with female axle, which i think is stronger.i've running mine for almost 2 years, with absolutely no adjustments/regreasing,and it still spins forever.
I'm super hard on my bike, and having 48 would be overkill. I just don't see the need for it when there are so many good rims, spokes, and hubs out.
Rims, spokes, and hubs are all made better and with better materials than they were 25 years ago. I loved the old Peregrine wheels and rode them all through the 90's, but I'm pretty sure the Odysseys I'm running now are just as strong and lighter than 48s. Unless you're just dying to spend money on new, more updated parts, then I'd stick with the 48's. Some guys on here have had the same Suzue front wheel since the 80s!
