That looks terrific, really nice workmanship!! The disc brake, B.D.'s standard, works surprisingly well! I had intended to try and upgrade to a hydralic disc but decided it was unneccessary.
The only thing i wish i had done before powder coating is a welded tube between the tops of the handle bars - i find they vibrate really badly, because of the long length from the triple clamp to the top of the risers; i would like to know if others, you, agree??
