I have a set of Walmer bars for sale, these are very wide but not their widest.I really enjoyed these and found the goldilocks size to suit me/ my 29+ bike after first trying their widest ones and then these. I'm giving something else a try now. They're about a year old, owned from new. I've tried to save the XL Curve Velo bar tape that is made specially for these that they came with, but some underside material has torn but not through to the top side. New XL tape is available from Giro Cycles, Curve's UK stockist.
The size is
700 overall width (bottom of hooks tip to tip)
550 between the hoods. See attached diagram for full specs.
£70 posted UK.
