Weaknesses:    Weyless logo is a little big

Bottom Line:   
I got this stem because I don't want to pay over $150 that has a liitle carbon look. I got 3 bikes and they all have one.

Bottom Line:   
Update: Torque to 40 in-lbs on each of the 4 handlebar bolts works fine - specialized recommends to not exceed 50 in lbs on their stems and carbon handlebar - I used the same advice!

Strengths:    Looks good, light and inexpensive - $30.

Weaknesses:    weyless sticker if you dont like generic, OEM parts

Bottom Line:   
Replaced 3TTT forgie stem with 120 mm r-19. Noticeably lighter than the Forgie and about the same stiffness. It has 5 degree rise which was hard to find but perfect for my TCR. I installed the weyless 191 carbon handlebar. Torqued 4 bolt to 50 in-lbs which is working well with the Carbon 191.

Strengths:    Has carbon fiber, is cheap, is reversible. Bolts are strong.

Weaknesses:    It isn’t the lightest stem out there, but it may be one of the lightest & cheapest carbon / al stems.

Bottom Line:   
I have the 90mm Weyless R19 stem. It weighed 145g with the 1” shim on an Ohaus balance scale with calibrated weights. The weights that Supergo advertises for these stems must be the weight of the stem without the 1” shim. Anyway, it is still a light enough stem, and I put it on my $3033 Cervelo Soloist Team RACING bike. For $40, this stem is a great deal compared to other carbon / aluminum stems, and it looks nice (the Easton EC70 carbon / al stem is $179). It doesn’t seem like it would have any problems with thread stripping (like the $130 Deda Newton) – and you don’t have to tighten the bolts so hard to get a firm grip on the fork steerer and handlebar. No creaks, is stiff and solid (I weigh 184 lbs, about 194 with all my bike gear on). Doesn’t get loose on rides, and I haven’t experienced any bar slippage yet in 175 miles. My only other choice for a stem would be the Syntace F99; this stem would be lighter but it’s a little more uglier.

I’ll update my review after some more months of use.
