New stem - standard or wide front clamp?

[frango]

I want to change a stem on my bike.
I've narrowed selection to two products, both 35mm long:

1. Kore Repute - cheaper, lighter, "conservative" design, 40mm front clamp (standard)
2. Spank Spike Race - more expensive, heavier, flashy design, 55mm front clamp (wide)

The bar to go with is Easton Havoc 750 Carbon.
I weigh 60kg (135lbs). I don't huck.

What would you choose?

I think it's totally up to you, with one reservation. Are you certain the 55mm width will not interfere with the bend of the bar? I've had a previous experience where my handlebar tapered at the same area that the wide-mount stem clamped. It resulted in a crappy interface and I had to use shims to make it fit. The stem I used was two piece (two separate clamps) so I wouldn't have had the same problem if it were solid through, but if the wide stem might hit where your carbon starts to bend up, it could be a dealbreaker.

Otherwise, the concept of carbon bars is A) lightweight, and B) added dampening/flex. A wider stem could reduce that vibration damping.

I have to check my h-bar for bends. But, it 19mm rise, so, bends are not "sharp"

just grab a ruler or set of calipers and see where the "55mm" mark is on your bars. My guess is that either will work.

My old style Marzocchi stem is 55mm wide on my Easton Havoc DH 750 bars.

I personally like the look of the kore stem better, and its cheaper, and its lighter.

I've had 3 or 4 pairs of Kore bars and one of their stems on my girls bike, no issues.

Aren't you an engineer? For shame; I'm watching you! If you so much as use the term fitment incorrectly, I'm issuing a red card.

Those are two brands that would be my last pick for any component.

nope, not an engineer.

I thought it was dampening for vibration, and damping for shocks, but I see that's wrong. I guess the high priced carbon bar will help keep the ladies damper too though.

Why is that?

At 60kg, I'd say you'd want more flex from the bar, not less. Not saying use a bit of rubber, just staying any new bar and stem combo will be stiff enough, some vibration damping and give might be more beneficial. Theoretically speaking. I doubt at 60kg you could notice.

Thx, skid

Thx, skid

All good, I just read that Sandwich had said much the same thing before me.
I'm pretty sure neither would have a relevant physical benefit and the theory behind it making you confident in your decision would have a far greater effect.
