'86 Ironman has Araya 20As; my early '88 Ironman "Expert" has
Wolbers. So maybe 1987 was a transition year?
.
The bottom line here is I'm not sure if one or the other
wheelset was standard and the Arayas were carry-overs from
'86. Both wheelsets are very nice, however, and if this
example has either set, the poster will be happy.

I just checked my brother-in-law's '87 Ironman Master specs
and his too are Wolber Super Champion Alpine 700C. So maybe
Araya 20As were holdovers from '86 that appeared on early
'87 models only, not sure.
.
My '86 Ironman has a complete Shimano 600EX groupset with
one exception, the Gran Compe brake levers! These are
original to this model and year, the Shimano 600EX calipers
notwithstanding.

The world of cycling is almost as strange as the cult of
cyclists. :-)

PS - The Wolber Super Champion and Araya 20A were similar
in weight and price, according to Frank Berto's 1988
Complete Guide to Upgrading Your Bike. Overall, however,
Berto rates the Wolber as a little better.
