In '88 they didn't always use Wolber on the Sirrus, they also used their own house brand 'Saturae'....

What I've quoted are from the spec sheets, which would be from late in the previous calendar year. Saturae may have been introduced part way through the year. And before anybody asks, no I don't have any pics, just the spec sheets.

When I saw the 1mm difference in chainstay length for '87 and no other geometry differences, I thought it might be a publisher's error. In fact, the 1988 might be the same frame, with the spec just rounded up to the nearest centimeter. There's certainly very little between them.

Chainstay length is measured at point where the centerline of the seatstay intersects with the centerline of the axle slot.
