Our tandem rides like a dream and fits me like the proverbial glove. But, certain road conditions cause my hands to go numb. I'm light in the handlebars, keep pressure off the various nerves, etc. I was blaming it on a resonant frequency in my CF fork, but I find that there is no buzz closer to the stem. It's got to be the Bontrager Al bars acting as a bit of a tuning fork. Short of buying CF handlebars which should offer more damping what are my options? Fill the hollow handlebars with expanding foam? Other?
Ventana El Ciclon, Walt Works 29er, Specialized Enduro (fixed up for my son).
look for ESI Grips
also maybe point the end of your bars down a touch - this is how I relive ulnat nerve pinching on my big sweep bars - I set them up by pointing them towards the rear hub and adjust for comfort from there - this is all on a standard 29er and 26" bike not tandems.
+1 for Specialized BG gloves
Got the gel gloves already. I think I'll do a re-wrap either with gel cork tape or regular tape with gel underneath. I'd love to get carbon, but a)$'s and b)we're a 340+ lb team w/o bike so I'm not going any lower pressure on our 28mm tires!
you can try getting some pipe insulation at the hardware store and cutting it down to fit your bars. you tape it to the bars (just the top), then wrap over the top. i would only put it in select areas where you put the most pressure on your hands. i have this setup on one of my bikes and it's luxurious.
