  • Best Stem Riser in the World

    “When I received my Soma Quill Stem Riser, I replaced my Nitto Technomic Standard stem with the Soma 'really long stem' on my touring bicycle.

    Pros: Great quality. I've tried lots 'o' stem risers, and this is second to none. This product outperforms the Nitto Technomic Standard stem because it truly allows one to raise it up as high as needed. It's construction is nice, and it has a nice finish. While the Nitto is a great piece of componentry (nicely made, high quality, etc) this is the best for a rider who really wants to raise those handlebars up very high, or bring them down to be level with the top of the saddle. I like the first one so much I bought another for my vintage MTB. Try em', you like 'em.
    Cons: None. ”
