I'm building out a Santa Cruz Highball carbon and am trying to get it as close to 20 lbs as possible. My problem is that I have been rolling with King hubs on all my bikes for 10+ years. The Kings are fairly heavy and I can't go back to slow engagement rear hubs.
Question: Anyone have suggestions on fast engagement, but light weight hubs. From what I have seen, the DT Swiss 180's and 240's seem to be the best option.
I have King hubs, headset and bottom bracket, and think their stuff is great. It's not that they 'became heavy' it's just that there are other hubs out there which are lighter in weight.
The question in mind has always been whether shaving a few grams in a hub is worth it, given the severe loading and harsh operating environment that hubs must endure. My king stuff is absolutely bombproof and easy to service - the same can't be said for other w.w. products out there. The question is, where is that fine line where a decrease in weight crosses over into the zone of unreliability? Obviously the answer to that also relates to the rider, their weight, strength, riding style, etc.
I bought an Extralite stem a few years back and several people on this site warned me of impending doom, however the stem has been prefect so far. Extralite's bar ends, on the other hand, crumple like a beer can if you hit a rock with them, so for most riding conditions I don't think the bar ends are worth the expense for the grams saved. I have no experience with their hubs though.
So after a few hundred miles on my Extralite hubs, I opened up the rear to add more grease to the freewheel and floating ring. After that I started to have a little skip engagement problem that soon turned into not engaging at all. What must have happened when I opened it up is something must have got in the teeth and didn’t let it fully engage which caused the tips of the teeth to get sheared off. I ordered a replacement ring and freewheel and they are working fine, now. So now when I have to open up the rear hub, I flush it out with WD40 and clean the hell out of it – no quick peaking!
I just don’t know how long the hub shell will last with the only lube between the floating ring and shell is motor oil (I think 10w-50). So these rims have become more of a race wheelset and I built up a second set with DT190. The internals of the DTs use SS engagement teeth, a few more grams but will last much longer than the Al teeth of Extralite.
But most of my hubs are Extralites, the UltraHubs SPDs and now the HyperHubs (more engagement) never had a problem with any of them them, even with their V-brake hub version. I could only afford to get one Tune Dezibel, just to satisfy my curiousity.
