After decades of riding my DA 7400 crank, I finally decided it was time to add a granny gear. I had already taken it to a 38/46 with a 13-32 and I have been able to ride it without many problems on the local terrain. But, I just didn't want to get to the point where I couldn't make a climb.

So, I picked up an NOS Ultegra 6503 and my old 7400 goes in the old parts bin. The crank I got is 172.5 and the old one is 170, but so far no issues. My mountain bikes are 175.

I do have to get the hang of proper shifting into the middle gear with downtube shifters. So far so good, although not as smooth as I would like.

I'm running a 30/38/46 setup so I can still run the old gearing and have a bail-out just on case.
