For those whom only think of Shimano products as nothing more than group sets, well, you would be missing out on their fine line of accessories. Shimano is now into computers, bars, saddles, seatposts, stems, cages, bottles, lights, bags, headsets, pumps, tools and apparel. Yes, it is not just about Dura-Ace Di2, anymore. Taking a plunge into Shimano’s Pro Series of goodies will not leave one disappointed.
So, I dived into the Pro Series Accessory pool courtesy of the fine
folks at Tweaked Sports in Glendora,
California. I was provided with a gorgeous 120mm alloy
Vibe 7S stem to put through its paces. The
alloy, black colored stem has two (2) steer tube bolts, and two (2) faceplate
bolts with an ingenious “Puzzle Lock” feature which basically locks the plate,
and thus, the bar, in place tightly with the two 4mm bolts. And, it works very, very well. As for the steer tube, only two bolts are
necessary with a cut-out to reduce stresses on the tube. Brilliant simplicity!
This Is One Stiff Stem!
While I have sung the praises of Ritchey stems (I had been
using the 4-Axis and C260), I had no idea what a stiff, tied-together front end
felt like until I tried the Vibe 7S.
Wow! First, there was the simplicity
of mounting, with only two bolts front and rear. They are a larger 4mm, versus the Ritchey
C260’s seven 3mm, and you do not need to unwrap the bar to mount it up, either
(as you do with the C260). Plus, with no
rear-facing bolts, mounting is a breeze.
Environmentally friendly packaging
Hands down, this is the simplest mounting system on the market
Easy, two-bolt mounting, and a cutout for reduced stress on the steer tube
As for the ergonomics, I thought the Ritchey’s -6 degree
angle was enough for me, but the Shimano’s -10 degree’s felt a whole lot
better. This surprised me, as we are
constantly being bombarded with advice that a higher stem angle will be more
comfortable for daily riding. Well, not
in my case. In addition, I have never
felt a front end more stable and planted on my trusty Trek 2.3 until I tried
the Vibe. I have bounced this thing over
all of the roughest pavement I know here in the greater Los Angeles area, and the front end has never
felt more solid and secure.
The Stats:

Sorry, Tweaked Sports. You are not getting this stem
back. Ever!
