It's totally OK to use the dogbone brazeon up the chainstay. That's what they put it there for. Whether the dropout braze on or the dogbone braze on is stronger is not super important in my opinion, because I think people break the bolt far more often than they break the braze on. I like the dogbone because you can use a much longer bolt, and get more threads engaged.
For the second question, I don't run the Duo, so I can't say anything smart about the load capacity with your mod. I will say that your mod looks super clean. Very nice work. Longer bolts with spacers like that are more susceptible to fatique, because of the lever arm that the spacers create. If you are the least bit worried about it, just carry one or two of those long bolts in your tool bag along with your tire levers. Carrying those spares will insure that the originals never break! :) On Friday, March 29, 2013 5:00:55 AM UTC-7, Tom Harrop wrote: > > Hi everyone, > > I have a couple of rack-mounting questions... > > Firstly, when I was building my Bombadil I completely missed (as in, > didn't consider using) the extra braze-ons on the seatstay near the > dropout, for getting the rack up a bit higher, and mounted my rear carrier > directly to the dropout.
