Question: How can I reduce the vibrations to the handlebars on an all-aluminium road bike? Either to the rider's hands or to the camera, or both.
I have been riding an all-alloy road bike for the last couple months, and while its so much faster than the MTB its terribly tiring.
I've suspected that its a harsh ride because there are lots of buzzes and rattles that come and go with different road surfaces.
A recent night ride demonstrated the problem in pictures.... I have a gopro on the stem and here are some comparison shots.
A video at night time was no good, but here's a short clip showing the buzz in sunlight.
Hand interface I've tried
Padded Cycling gloves - helped a little with the hands, but they were cold. I've been wearing my full hand cycling gloves with no padding.
Hand positions - I'm 99% on the hoods, either near the bend or up on the brake hoods. I never use the drops, they're out of reach, and the tops only occasionally. On a long ride I might put hands on top of the brakes for some variety ("high hoods")
Bar tape - I've fitted some bar tape which is labelled as "cork" but was really a diamond-shape of firm foam. This helped, but the hand position is now unnaturally squishy.
Yet to try:
A shorter stem, the old one is 120mm long. Finding one is difficult because its an odd sized quill stem. Still searching.
A replacement front fork of steel or carbon ? Seems like an expensive solution for an older bike.
Lower tyre pressure helps, but I'm over 100 KG so I can't really go lower than 100 PSI on 25mm tyres.
Replacement bars ? Would carbon bars be any better at damping the vibrations?
Camera mount I've got one of these on my stem. There's a layer of dense foam underneath which helps a little.
Searching web sites like instructables.com has returned steadicam-type mounts for hand usage, but not for biking.
Summary: How to reduce the road buzz that is transmitted through the fork/frame/stem and the handlebars?
