I had Keith Bontrager build this custom cyclocross-based frame &
fork back in 1989 and it remains one of my favorites to ride. Though
unusual for Bontragers to be fillet-brazed, I requested this and
chrome, too. (Keith termed it a "satin" chrome, though I'm still
not sure what that is - maybe sand blasted? No matter, it has held
up well and does not show scratches from rough use.)
He
added nice little touches like a chain hanger, frame pump peg, color-matched
Silca pump and Gipiemme horizontal dropouts. The fork crown is a
sloping type. It has a high bottom bracket (11.70 cm) but handles
well on the road, too. 72 degree head tube, 73 degree seat tube,
with 16.70 chainstays. Though I usually ride a 56 cm frame, this
measures 55.5, probably because of the high BB. (Keith put me through
many pages of measurements and really dialed this one in for me.
He really knew his stuff.)
The
bike has seen many different configurations, starting as a triple,
with a 7-speed rear. Later, the horizontal dropouts allowed use
as a single speed for a number of years before I had one of those
built. It's now a 1x7, using a 13/24 Dura Ace freewheel and a 38T
FSA chainring mounted to an old Sugino triple crakset with chainguards
both sides.
The
original Mavic MA40's finally gave out last year and I had a set
of 32h DT Swiss RR 1.1 rims laced to the original Phil Wood hubs.
Though I have run knobbies, I'm currently doing a mix of pavement
/ dirt roads with it, so have mounted some bulletproof 700 x 35
Vittoria Randonneur Hypers (that actually measure 37mm). They fit
fine, though the fork is nearly maxed at the crown and the bridgeless
chainstays have allowed these on the back, too.
Other
current components:
Deore XT rear derailleur
Suntour barcon
SRP Mr. Grumpy cyclocross brakes
Interrupter levers up top
Shimano 105 headset (original)
Suntour XC seatpost
Ritchey WCS V4 pedals
Finally,
a crowning touch: a custom fillet-brazed stem by Steve Potts. (I've
included a "studio" shot of this.)
I'd
appreciate word from any other owners of fillet-brazed Bontrager
cyclocross bikes out there!
