I recently purchased a brand new Extralite Road stem and just took delivery of it yesterday. Gorgeous piece of kit! However, I was confused—every photo I've ever seen seems to show the stem consisting of Torx bolts. The version I received is outfitted with hex bolts instead. Even the instructions that it came with specified Torx.
Upon further investigation by emailing Extralite, I found out this is an old version of the stem from 2009/2010 that used the older hex style bolts. The part about the newer instructions with older stem still confuses me...but is there any reason to return this and buy the new version?
Extralite wants nearly 50 CAD for the 6 replacement bolts, which is a bit steep. With proper care will the hex bolts be ok, or are there major issues with the old style that I should be concerned about? It seems they have made some changes to the clamp as well, but I don't know what those differences are.
I wish companies and online stores did a better job of making their versioning more apparent, I probably would have bought the stem somewhere else had I known.
The new torx bolts make stripping the very small bolts much harder...
use lots of Ti prep, lots of carbon paste and only 80 % of the max torque setting for the bolts..
I have the newer model and only run 2.5nm of torque on those bolts.
The older bolt kits are really easy to round out so be careful.
