Greetings All,

I am looking to put aerobars on my Zero and was wondering if anyone has had any experience with the STI adapter made by Profile Design. As for aerobars, Im leaning toward the Aerolite aerobars by Profile Design, with Dura-ace bar end shifters. There are no reviews of the bars in the review listings, and the adapter is not listed either. The bike is a 2001 Giant TCR Zero and still stock.

Pictured below is the STI adapter

Thanks in advance.

According to the Profile Design web site. Down-tube mounted cable splitter allows for the use of two different shifters for each derailleur. CNC machined aluminum with plastic cover. So you could use the bar end shifters on your aerobars and still keep your STI shifters and not have to swap cables between the two. I dont know what one of those cost. Maybe they are a new item for 2003.

It looks to me that if you want to use the bar end shifter, you shift the STI into the smallest cog and then have to do all of your shifting with the bar end. In other words, you can shift with either the STI or with the bar end, but you won't be able to interchange automatically during the ride.
Still a good ideaMatno

but it looks heavy. Not to mention the extra cable & housing. I supposed it might be nice if you used it just for the rear shifter...

Profile's web site is woefully inadequate when it comes to product descriptions. For example, what is the UPS, or the "quick stop"? They look cool, but what do they do?
