Customer review of these products:

StarStarStarStarStar Straightforward, does what it should do.

Product: Soma High Rider Stem Adapter (Threadless steerers): Black
Ownership: a month
Tech Knowledge: somewhat high


huge riser + all the 1-1/8 stem options in the world. Reach for the sky.


Adding a tall stem, then some very wide bars places a great deal of leverage on a frame. I can feel mine flexing and it was disconcerting at first...testing has revealed it's only flex and the whole setup is quite strong, and all it took was a psychological adjustment to get used to it.

Other Thoughts

If you go very high and wide...using this tall stem may incur some increased flexiness. This could possibly be a positive (as it has been for me) in the sense of dampening road vibes and softening the bike's feel.
