I have a question about mounting a rear rack on a bike without eyelets or braze-ons. I know that there are nice p-clamps that allow one to easily attach the rack to the seatstays (e.g. http://www.jandd.com/detail.asp?PRODUCT_ID=FCLAMP). But what fixes allow one attach the rack at the dropouts without brazed-on eyelets? Or can those p-clamps also be used at the dropouts?
The stays in question are titanium, so I'm not worried about strength or about scratching any paint. In the past I've used a rack that mounted only on the seatpost, but it has a low weight limit, and I want to be able to carry two full panniers.
Also, if you have a road bike, some road bikes have a triangle by the dropout and I believe Campy sold a little adaptor that allows one to use that as a lower eyelet.
I have a custom rear rack/pannier on my Lemond (no eyelets) that uses this. Basically it's a small rubber grommet that will fit in the triangle and I have the lower arm mounted via a nut and bolt through this grommet in the rear. It does limit the weight as it wont be AS secure as the QR mount or an eyelet but works fine for the 5 years I've used it to commute to work.
