Was interesting to see they do a TT version which puts them in the domain of Mdcc Tester, i could see the advantage for helping on windy days, minimal gains an all that
Not so much minimal gains as no gains at all. I've ridden motorbikes with more steering damper than they need*, and I can assure you that's the last thing I'd want on a bicycle. On a TT bike, it would be truly horrible. More than a bicycle needs is any steering damper.
*I've also had an epic tank-slapper on a VFR750 (RC24 or RC36, can't remember which as I've ridden both), so it's fair to say I've also ridden motorbikes with less steering damper than they need :-)
