For road bikes, or all bikes? is the 1 1/8" straight headtube being replaced by 1 1/8" x 1.5" tapered headtube? Does this give additional support to the fork? Do you think it's safer when you have a carbon fork with a carbon steerer tube to have this taper?
I'll be ordering a Ti road frame soon and wonder if I should be getting this new taper. I already have a 1 1/8" carbon fork with a carbon steerer and if this is going to be a big improvement, I'll order another fork that's tapered 1 1/8" x 1.5"
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
I see absolutely no benefit to the tapered steerer/headset design except to obsolete your current bike. The increased stiffness has to be of negligable value. Most of the road forks I've seen with that configuration are dedicated to a particular frame and I haven't seen any on the aftermarket yet. Ask your frame supplier if they can supply a suitable fork if you choose to go with the tapered design.
