Feedback From Ross the Manufacturer on this particular bike:
(I recently checked in with an executive at Ross to learn more about this particular bike and t I learned the following):
Hi George,
Thank you for reaching out and for sharing the photos. What a great vintage piece your family has held onto.
Your bike is a Ross Gran Tour Sport, most likely manufactured in the late 1970s. It probably says it in the first digits of the vin. The color, frame construction, component mix, and decal style all match the model line.
To answer your questions:
1. Year: Likely between 1977 and 1982 based on the decals, components, and SMA/6 safety certification sticker visible near the crank.
2. Model: Ross Gran Tour Sport – a mid-range sport touring model, positioned above the base-level 10-speeds but below the high-end touring bikes.
3. Original Retail Price & Current Value:
When new, this model likely retailed in the $110–$150 range depending on the year and configuration.
Current resale value depends on condition:
As-is (original, unrestored): $450–$650+
Fully restored with new tires, cables, etc.: $1500+
There's a real collectible market for these.
4. Size: Based on your measurements (20" seat tube and 22.5" top tube), this would be considered a Small-Medium or roughly a 52 cm frame, suitable for someone approximately 5’5”–5’9” depending on their inseam and riding style. The 31" stand over height is also consistent with that range.
This bike was a solid intermediate-level model, known for being durable and well-equipped for recreational or light touring use. It came with better components than entry-level bikes and was often favored by casual cyclists and commuters who wanted performance without the cost of high-end racing models.
Specs Summary (typical for this model and year):
• Steel lugged frame with hi-tensile tubing
• Shimano Eagle rear derailleur
• Dia-Compe side-pull brakes
• 10-speed drivetrain (2x5)
• Alloy wheels, 27" x 1 1/4" with gumwall tires
• Mesinger saddle
• Factory rear rack and reflectors
Given the bike’s condition and originality, it's an excellent candidate for restoration or display, and certainly collectible among vintage bike enthusiasts.
My father designed this bike, so thank you for sharing it.
If it was me, id fully restore it and hold onto it or sell it at auction for premium price.
Wish you all the best with it and thank you again for sharing. I truly enjoy seeing how our Ross's have held up over all these years.
