Bicycle Mechanics - Bar-ends on Trek 7.2

Hi there,

When riding longer distances I sometimes get tired of the same position on the handles and a friend suggested: bar-ends...

So I am searching, looking for advice and so on...

From a purely technical point of view, how can I put bar-end with those handles (default ones on Trek FX 7.2):

Also, I read somewhere the Trek handlebars are not tubular, I mean they're not round all the way... I can't find where I found that info... but is it true? or are they standard?

#1, don't believe every thing you Read

They are in your hands, verify, measure ! buy a caliper ,
and a tape measure.

most bars have a center, bigger to clamp by the stem, though the rest is smaller.
straight MTB bars .. that OD is 7/8" aka 22.2mm

I like Ergon combination wide surface grip and bar end GR5 is the long one,
GR2 is the shortest bar end

you tube is your friend.

the best way I saw to 'cut the grips" is to lossen the shifters and brakes slide them in a bit
bang on the end of the grip with a hammer and let the bar punch thought the grip like a circular knife or cookie cutter from the inside of the grip.
then grab the little rubber plug that is now in the bar out with a needle nose plyer.
slide the grips in an inch or so. a little rubbing alcohol will let the grips slide. cutting them with knife usually looks sloppy.
now clamp the bar ends on.

I don't know how the ergons work but this works great for the baisic bull horn style

this also only cuts the center of the grip so the nice shape of your current grip isn't lost.

+1 for the Ergon combo grips. Sooooo comfy.

I don't know how the ergons work

clamps on the bar, .. the 1 bolt, in the bar end, squeezes around the grip end
and the grip squeezes the end of the handlebar..

If those weren't round, the brake levers wouldn't fit properly. There may well be some Trek bars that have a weird non-round cross-section closer to the stem, to reduce aerodynamic drag, but those are likely to be drop handlebars, and expensive ones at that.

ok, I found the source of my initial doubt, and it seems that I will be fine, although I was right to be cautious, here is why:
I have an FX 7.2 and the (official) page describing the FX 7.3 (http://www.trekbikes.com/fr/fr/bikes/road/fitness/fx/7_3_fx/#) claims that among the features the 7.3 has compared to 7.2 is the "IsoZone handles and handlebars", which would look like this:

And the subject seems to have been discussed on the forum too (http://www.bikeforums.net/archive/index.php/t-686254.html for example).

So thanks for your help! I should be fine without changing the handlebar!

Wow, that's a new one for me, I must admit! I wonder if they ever got the bar-ends out for that weird bar....

Off topic, I thought Freddie Mercury wrote all the songs?
