Well, I picked up a brand new Castro Valley on Friday. Put a Blackburn rack on yesterday, and now I’m down to eight speeds. The bolt that attaches the rack to the frame interferes with the chain when it’s on the smallest cog.
Anybody have a fix for this? I’ve already reversed the bolt, so instead of the nylon lock nut being on the inside of the frame, it’s on the outside, and the smaller bolt head is on the inside of the frame. Still not giving me enough clearance to use the chain on the smallest cog.
If nobody knows of a fix, how do I adjust the derailleur limit screws such as that I can’t shift into that gear accidentally?
How much space do you need? I’d take the bolt to the local hardware store & look for something with a smaller head that’s the same size, most likely a button head screw.
Depending on what the chain stays are made of you could put a washer on the axle to give you some extra space. Kind of mickey mouse but it should work on a steel frame. They say not to spring an aluminum frame, but I’ve put a 130 mm wheel in a 126 mm spaced Klein that I use for a rain bike with no problem.
The blackburn bolts where to long for my bike also. I use a water bottle screw that is fairly short on the drivetrain side. Most shops should have a collection and you can find one that works.
If you really can’t find one, PM me, I have a few extras and I could drop one in the mail for you.
Get a low profile cage bolt, the ones with the rounds head, and run it thru from the inside of the frame, then put the rack on(on the outside of frame), then just use a nylon insert nut on the outside.
Almost all screw holes in the drop outs for mounting rack, etc., are already threaded. You shouldn’t need a nut on the bolt to secure it. Get a shorter bolt, just long enough to go all the way through the hole but not long enough to extend beyond. If you are still worried about something vibrating loose later, use some loctite on it.

That’s the solution I was leaning towards, especially since that’s exactly how the fenders are mounted. I wasn’t sure if that setup would be strong enough for a loaded rack, though. I’ll try it, thanks!
That should be more than adequate to manage at least 40 lbs. Most racks are not rated for more than that and then there are significant handling issues when one chooses to carry more weight that this on a rack. Your bike can become unsafe at nearly any speed when you “overload” a rack.
