Will This Rack Work On My New Bike?
 

I have a Topeak Super Tourist Tubular Rack (w/ spring) that I was using on my Schwinn:

I just bought an Adams Trail-a-Bike for my son, and I'm wondering if this rack would work over its 20" wheel since I won't fit on the tow bike anymore:

The bike has braze-ons on the seatstays and eyelets on the dropouts, but I worry that the rack would be too tall. I don't plan to load it up with heavy panniers but a nice picnic lunch from time to time would be nice, or a bag to pick up some quick groceries, yard sale finds, etc. Any suggestions?

Also, can anyone recommend a nice 20" fender to match my Schwinn's PB Cascadias?

Most likely not. I put a rack on my Trek tagalong. It was a very small rack (11" legs) I picked up in the LBS - The sticker on it says EZ-1 rear rack from Wheel & Sprocket. If I recall I also had to modify the holes and drill and tap the dropout to make it work. I also had to cut a piece of PVC pipe to hold the hitch up high enough to clear the rack on my bike. I think a planet bike Eco rack fit on the kids 20" ers, but they are now long gone
