good idea
like the t's too,
you can use a giro tab on the top of the down tube or under the top tube just behind the headtube with a slight angle depending which side you run the cable , dead easy to drill n tap the tube 4mm (may void your warranty
) been going to do mine but velcro is easier
tbh i don't know why companies don't bung one on the frame near the headtube , wouldn't be in the way if you ran a giro and would save nicking the laggy out yer wangers to tie the cable up if you run a single
course they'd be useless on a brakeless frame
