These bars are extremely light, if not the LTD model. They obviously have a super cool look both with the matte finish and aero lines. There is a more pronounced flare to the drops than most road bars. The size 42 measures 42cm from drop end to end but at the hoods it's 39. 3cm is a perceivable difference. Most bars are not 1:1 but the Cinelli Ram bar I was using previously measured 40.5 at the hoods for the same "size" bar. If you think you're crowded with your current bar, consider sizing up. The other consideration that was mentioned by a few others was the reach. It truly is larger than many bars so you'll need to adjust with the stem length. I'm glad I came across that detail before buying the 3T LTD stem which is pricey. I just went by the numbers (reach + stem length) and the fit came out great.
Combined with the 3T LTD stem, the set just looks top shelf and is a joy to ride. I also appreciate that there is enough round bar section to mount an out-front and bar accessory bar that I use to mount a headlight.
I found the threading of cables to be not very intuitive. There were no instructions on how to do it but a pair of plastic tap sleeves suggested to put your cables through them. If you do this you will likely ruin your cables because they will kink. The objective is to get the housings through. I found that using the cable taps was useful but only with a sacrificial cable passed first into the tap from the shifter side, out the tap and into and out of the housing. Then feed the tap and housing together out the shifter side. You can pull on the cable in any way to get the housing to come through the bar. You'll kink the heck out of the cable but who cares, and it's quick and easy. You'll also need to thread the housings side by side in only one way: forward to inner/ rearward to outer. That means that the housing you want exiting the shifter port nearest the inner side should be placed on the forward side at the input. When you're installing it this will make sense. If you don't do it this way, the housings will be crossed inside and you won't be able to get the second one out.
