88 Voyaguer Fork RAKE or front end TRAIL Measurements

Has any one with a 84 to 88 Voyaguer measured either:
Fork Rake
overall front end Trial
The catalog does not provide rake or trail, but shows all Voyageurs had same head angle of 72 (& seat angle 74) for a 23" frame, so the rake and trial are most likley identical for these years

The 86 Passage and 89 Voyaguer had slightly steeper head angle 72.5 with same 72.5 seat angle

Interested in how much Trail a 88 Voyaguer has to compare to low trial alternatives.

TIA

I measured the fork rake at 54 mm (used a 4' long level aligned on the steering axis and a right triangle from the level to the center of the axle). 54 mm is 2.126" or within 0.001" of 2.125" = 2-1/8". I suspect Schwinn speced a 2-1/8" fork rake on the 1988 Voyager, and possibly all the touring style Voyageurs (84 thru 89)

The TRAIL & FLOP calculates to be 56.0 mm and 16.5 mm respectively using 630-32 wheel/tire and the catalog value of 72 for head angle. Definitely a mid to high trail geometry, but approx 6.7 mm less than a Gunnar Grand Tour, (62.7 via Gunnar bike fit program) which seems to be a good proxy for a modern 700C touring bike.

John, I used to have an '88 Voyageur and you might be able to get a fairly accurate estimate of angles from this photograph:



That bike is now in the hands of BF member Southpaw Boston and I'd be willing to bet if you reach out to him he'd be able to provide you with detailed specs.

Azorch, Good idea, especially sicne yours looks to be a 25" frmae. I have a 21" frame and the 72 catalog value is for a 23" frame. I'll ask SPW or measure the photo for the 25" frame angles. I have a Wixey WR300 digital angle gauge on order, so I'll be able to measure the 21".

John, I haven't formally checked, but your measurement of 54mm for rake seems about right.

Azorch, using using your picture in my CAD software and rotating the picture such that the top tube is at 0 degrees, I'm getting 72.5 degrees for the head tube angle. Assuming there's no lens distortion and the angle of the picture is a perfectly perpendicular, I'm confident to go with this number over the published spec of 72.0.

SPB, the Catalog value of 72 for Head Angle is for a 23" frame. I apologize for not making it clear earlier.

Your Voyaguer appears to be a 25" frame, so the 72.5 measured from the picture, is possible for a different frame size. The trail would decrease by 3.2 mm, 56 to 52.8 mm, for a head angle change of 72 to 72.5. Still mid to high trial.
