Question: I have a Profile Design H2O OS Stem which is oval shaped. Will the Topeak Bar Extender mount to it, or is it only suitable for round/non aero bars and tubes?
Document: I had too many things attached to my handlebar on my road bike. The bike that I have has its shifters located where it blocks part of the handlebars, so much so that I had to install a smartphone holder and a headlight light in a way that I couldn't use them the way I wanted. Now that I have the Topeak Bar Extender, I got my handlebar space back. The design of the product allows for installation in several places on the bike, including the front stem with a very large diameter.
I mounted two lights with this thing. It stays very stable and didn't move at all during riding. I have aero bars mounted on the handle bars and didn't have the bar space to mount lights without this product.
I love this bar extender. I mounted this bar extender under the handlebar stem. I mounted a 1600LM light which mounts with a O ring type mount to the center. On each side of the the center light I mounted LED flashlight type bicycle lights. Each of the lights has a high, low and flashing option. This gives all kinds of lighting options for just about any condition. It looks cool too. Another great product from Topeak.
A real lifesaver. My new bike had oversize and teardrop shaped handlebars. Normal accessories such as lights, bells, etc. with circular clamps were not big enough and were the wrong shape to fit the bars. WITH the Topeak extender, I could add several in just about any position. Very stable, once it's attached it's not going anywhere.
This item has not been used yet, I did however mount it on my bike. It fit the stem of my bike even though the stem is more square than round. Seems to be a good secure fit so far. Not sure where the measurements come from but this thing is small. I had planed to mount a small handle bar bag on this product, no such luck. I do however have room for GPS Iphone flashlight.
This bar extender is great for adding mounting space for lights ect, and will fit on oversize bars or stems. I am using it to mound dual lights on the stem of my Rans X Stream and it works very well with multiple adjustment points.
I use mine for two headlights. On a bumpy road or trail, I have my lights flopping up and down just enough to be really annoying.The bottom line is that the Topeak Bar Extender has a clever design that offers a lot of flexibility in how it can be used, but it suffers from some design issues that frustrate when trying to install and adjust it.
I think the design team of people at ToPeak has done a great job interweaving there products to work together. I need this bar extender to hold my headlight ToPeak WhiteLite- Race & RedLite that fit on the ToPeak handle bar bag holder perfectly.Very happy highly recommend. I wish I could share a photograph to show how it all work together.
I own many Topeak products and have generally been very satisfied. While the Topeak Bar Extender is useful and has a versatile design, it falls short of the standard set by their other products. The method used to attach the Topeak to your handlebars is not the best. I had to use lots of rubber and really crank down on the Allen wrench to keep it from slipping. The angle of the extender bar is also adjustable - a very nice feature - but again the method used falls short.
At this location, the readings are very accurate and it's very easy to see and use the computer. The Topeak Bar Extender is very easy to install, is well-built and is very sturdy once installed and it looks great too. The design offers excellent flexibility for mounting just about anywhere at various angles and lengths. Highly recommended!! !
Answer: yes
