the Trek has 8spd.shifters.on the Trek When I get to the 8th cog

Answer
Hello Emil,

First I am so sorry kept you waiting so long on a answer.
My interprovider was down for a while.
But here I can now answer your question.

Normally you can't shift a 9 speed cog with a 8 speed shifter.
But I now out experience when you adjust this good it is possible.
And you or your lbs is good in it!

So, it can't be hurting your bike or cogs.
Further I only wish you further a lot of cyclesmiles.

enjoy.

Michael
