I have been eyeing up the LOOK KG281 and was wondering if anybody knew what the frame weight was for this model.

Thanks,

The Look web site, www.lookcycle.com, lists the weight as 1750 grams, which equals 3.85 lbs.
That's with a 360g HSC 3 fork, The frame is 3lbsJ.S.

Aside from weight, Looks have some non-standard geometry so you need to look(no pun intended) at that also.

Check it out. I have a KG271 which has the same geometry as the 281. Comfortable, stable, and, well, FRENCH. I love it. I've rode many different bikes, and this has been the best.

I had a Trek 5200 for 8 months or so and just built up a KG281. I love it. The geometry does not seem unusual to me, it matched up well with the Trek. Built with Dura-Ace the bike weighs in right at 17 lbs. Rides great and you know there won't be 10 other people at the group ride with the same bike.

the seat tube angles are really slack for the smaller sizes. In fact the seat tube angle is 72.5 degrees for all frame sizes.

The top tubes are a bit longer to compensate for this, but for example 52CM frames are normally given a 74 or 75 degree angle STA.
Get fit on one before you buy! Otherwise your center of balance might be too far forward.

Don't you mean that the center of gravity will be too far back if seat angle is too slack?
Knee over pedal relationshipsimplegreen

To keep the same knee over pedal relationship, you'd have to move the seat forward relative to the seat tube. This moves the rider forward relative to the wheels. The Look frames come with long wheelbases, so one or two centimeters shouldn't be a big problem. People with short femurs might want to get something with larger STA's. I think for the larger sizes it doesn't matter too much.

Hope this makes sense!

I see what you mean about smaller sizes, but in my size, everything looks pretty standard.

Look KG281

55 cm (center to center)
Seat tube angle 72.5
Head tube angle 74
Top tube length 569 mm

Trek 5200

58 cm (center to top of seat tube)
Seat tube angle 73
Head tube angle 73.8
Top tube length 570 mm

The .5 degree difference should only affect your position by 5mm or
so. Go with the one that you like most!
