How to reduce the vibration?

Hi
A friend is trying to reduce the vibration he gets from the front part of the bike.
He has an aluminium frame, forks and (alu straight) bars; he does not want to change to bigger tyres and wants to avoid changing the fork.
Any suggestions for the bars, what about the mountain bike carbon bars?
What about vibration absorbing grips?
Advanced thanks!

Carbon would not be the way to go to get rid of vibration, I would say some nice steel bars would add a little flex to the general stiffness of alu....everything...
He could also swap the tyres out for something stiffer if they are soft and not gettig the pressure in or something softer if they are too stiff.
Vauge I know but tweaking is the way to do things.

FWIW I swapped the steel forks on my Fuji Track for carbon ones and there's definitely less 'road-buzz'.

i swapped out a pair of alu forks for some carbons and the they used to buzz like fnck. stopped when i swapped them

"a freind of mine"...... ha!

carbon forks = smoother ride.

tell your mate to either man up... or get some carbon forks.

As above

Carbon is definitely the way to go, I've had improvements on bikes with steel and alu forks, just don't get anything to extremely light or race orientated.

Wear gloves
Use padded bar tape
Why does everyone go for carbon bar swaps and bollocks?

tell your "friend" to try out puffy griptape first, might make enough difference for "him"

Whoops, I thought carbon would be stiffer...

Carbon forks, saddle back (and possibly therefore down) 5-10mm, bars up 10mm.

Instant armchair.

Is your buddy running 160psi by any chance?

^that too.

I've been hacking it down cratered country lanes recently, and no problems at 90-95psi*.

*caveat - I'm 10stone/63kg

BMMF.. 90kg+ and I've never pinch-flatted running 90-115psi nor do I have sore hands/wrists.

Suspension stem.

Is this vibration caused by stiffness?

If so, is your friend running a radial wheel? Change to a crossed wheel.

Change to a fatter tyre, possibly drop psi a tad.

Consider wider handlebars (for flex and better control over vibration)

{edit}

How can your friend just rule out fatter tyres like that? Must be by far the best way to deal with it?

I quite like the skateboard bushing in the stem idea, doesnt look to bad either, really need it at times on the bad Dublin roads.

EDIT: Maybe he ruled them out out of necessity, frame clearances too small or the like.

Too heavy and doesn't work very well.

He has an aluminium frame with a straight bladed fork. Thats going to be stiff.

Logical options would be to change the fork & tyres.

Changing the front wheel & handbars would help too.

Logic? You're on the wrong forum DFP.

Gel pads, bar tape and gloves will take the edge off of the buzz for sure. It's hardly Paris-Roubaix...
