Purchased these to convert a Burley drop bar tandem to a flat bar set-up. Sold the tandem and now these are for sale. The bullmoose bars are tig welded and the Rivendell inspired version not the Fairweather. The quill adapter is the same as the one on Rivendell's site.
Bullmoose width 61cm c-c and 150mm reach $125/shipped
Nitto quill adapter $40/shipped
$150/shipped for both
The Rivendell site sells a fillet-brazed bullmoose for $180 and the adapter for $75
