enforme said:As I understand it, Specialized (and later, HED) made a tri-spoke
carbon wheel with freewheel threading. It could be adapted for front
(100mm) or rear use (road or track (120mm) spacing) by switching to the
appropriate axle and spacer combo.
Question is: did either Specialized or HED ever make a threaded-hub
wheel that could be used ONLY for road rear use? That is, was there
ever a model with threaded hub that did NOT allow the user to alter
axle and spacers to fit as a front wheel or for rear track use?
Thanks much for the wisdom... ccc
Who knows what *might* have been made! ;-)
However, all the freewheel DuPont trispokes (or Specialized or Hed
trispokes) I've seen can be made into fronts by changing the spacing.
Little known factiod #1: Even if you don't have the M9x1 "front" axle
set you can still make a freewheel rear into a front. Using the
existing M10x1 axle set, get the spacing to 100mm and the axle length
to about 108mm, then grind down the OD of the axle to 9mm over the 4mm
length on each side that fits into the fork. The M10x1 threads are
neatly consumed in this step so the smooth 9mm diameter fits right into
the fork ends.
Little known factoid #2: Some loose-ball front hubs use an M10x1 axle
with the last 4mm or so on each side ground down to 9mm OD... I've used
an axle from a Bontrager Select hub that's like this. There are
probably others as well.
