Sorry I do not know. I feel your pain. I came to this thread to see if anyone knew what spoke size I need for my 2013 8.3DS.

I have had a few replaced, and was given a couple spares at my LBS last trip. They measure ~11.5 inches (with standard J-bends). However I didnt see the actual size on the box he pulled them from.

Now, ~11.5 inches is ~292 mm. But when the next sizes up and down are in increments of just 1mm, it makes me a bit uneasy. I believe you'd have +/- 1mm to play with, but I too would like to know.

What I find amazing is I cannot go to a Trek site and find a manual that will tell me what size I need! The "user manual" I got with my bike was the exact same manual as I got for my 5 year old daughters Trek. Not bike specific.

I can appreciate there are calculators out there that require measurement of wheels/hubs etc, but I'm just looking for stock length!

Anyone know?
