Stem Help

[Mallory]

Sadly one of my stem bolts actually snapped in half today, so i'm now in need of a new stem.

I currently have a planet x 110mm 6 degree stem.

When seated on the saddle and on the hoods my arms are locked straight and the bars are in alignment with my wheel hubs.

I occasionally get some pain in my shoulders, could this be due ti stem length/rise or does the above seem correct?

Front hub should be obscured by the bars, when you are on the hoods. Arms shouldn't be locked straight though... should have a bit of a bend in them, imho.

A snapped bolt doesn't mean you need a new stem. If the other have of that bolt is stuck in the stem, remove it, then just whack a fresh bolt in.

Not enough bolt showing in order to remove, plus I don't know what damage it could have done to integrity of the threads.

Provided your seat is placed correctly, an old trick is to place your elbow on the end of the seat and see where the tip of your fingers end up. In theory the bars should just reach the tip of your fingers. Not sure how accurate it is but its what I have currently used.
