Question: how do I install these onto the bike?
Document: Put these on my old MTB when I decided to add drop bars to the bike.. these shifters work perfectly!
I put these shifters on my Trek 7200 hybrid after converting to drop bars. They've been on the bike for a while now, and work perfectly. This is an amazing prices for such good shifters.
These are awesome shifters. I replaced the twist shifters on my bike, as I made it electric and i wanted twist for the throttle. I have the smaller diameter bars, and i used some old rubber and wedged it in the clamp area. So far so good.
I an enjoying these shifters on my GMC Denali Road Bike !I replaced the stock 'RevoShift' units on the Denali - those worked fine, but took up too much handlebar space, and the rotating motion to actuate them was 'un-natural' for a road bike.Viola !
Warning these will not fit on handle bars that are much smaller than 26mm. 26mm is a common size but on a cheap road bike I had the handle bars were closer to 20mm. Anyways these work well on road bikes if you cannot afford brifters. They are better than down-tube shifters because they require less hand/arm movement to shift. Great for getting old bikes back running but you will probably need a conversion kit.
At last, an economical way to add cruiser comforts to a 90's road bike. I could only find these shifters on your website, way up in the NE but the shipping was reasonable and quick. A warning that there's no adjuster knob on the 2(which handles three eaisily) shifter could've saved me some searching on the floor or a parts diagram would do. Only took some quick adjusting and the indexing was perfect. Thank you for saving my touring bike from the scrap heap and me from drop tube shifters.
Well, I no longer have to reach or lean over to shift. These shifters allow many different applications for mounting and use. Good!
I was looking for a way to convert my down post shifters to handlebars. This has worked fine. I only used the rear shifter, I placed it on the right side close to the stem. The digital is off a little when shifting but it is fast and easy and much more convenient.
Answer: yes
