Cannondale Delta V 700 and out of alignment frame

I had this bike for 20+ years and served me well. I was thinking to upgrade components on the bike, but while talking to local bike shop during the last service, we discovered that bike frame is "out of center". The rear triangle has moved about 10mm ( measured with ParTool) to the drive side. This is aluminum frame, so no repair is considered. While there are not any visible cracks in the frame, I wonder if it is good idea to upgrade components, considering frame is out of alignment. What are your thoughts?

Scrap it and get a new bike. You will like the ride a lot better. MTBs have come a long way in the last 20 years.

I was looking for the opinion if this miss-alignment will interfere with either shifting or riding. As the bike aged, so did I , and my riding is limited to fire access roads and such, so not much technical, but still like being in the mountains ( not too crazy about street riding).

Donít upgrade components on a 20 year old misaligned frame. Not worth the hassle or headache.

Get something like a 27.5 or 29er plus bike. Good all around trail ride. You will thank me later. Do some demos.

Something sounds wrong. I'd believe that a steel frame lost its alignment over time, but chances are that no Cannondale aluminum frame, other than one that's visibly bent from a crash, has ever "moved," despite what a mechanic using a Park alignment tool says. Not saying it's impossible, but it's extremely unlikely.

If it were me,I'd take it to a local framebuilder for a second opinion.

What was used as a reference to say it was 10mm out? That much drift would show cracks and frame damage.

I had the bike from the beginning, so I know there was no any major crash that would twist the frame. I did not believe it myself, so I did simple check with string and there is some miss-alignment, I can see at the seat tube that frame is out, but there the difference is about 3mm. I think I will keep riding it until I find some good deal on the new bike... I am approaching 70, so the only riding I do is for fitness, no single tracks any more .

10 mm is difference that they found when comparing left and right side using the frame point next to BBracket. I can see frame is out with simple string test, but at the seat tube it shows only 3mm or so. Maybe it is time for replacement.

Thank you all for chiming in. What muddy the water is that I just replaced wheels with nice mavic,, which have new hubs that would take wider cassette; 2 years ago I had to replace shifters, so there are lots of replacement/upgrades that already happened. I was looking to swap to shimano m4000, but may be it is not worth it.

Part out the bike on craiglist or ebay and then use that money towards a newer decent bike.
