And this of course is not true at all!Dan Martin, like Valverde, is a puncheur. Puncheur's do not make for good climbing helpers. They are great for getting stage wins, but very poor as helpers. The type of climbs they are great at are the type that helpers aren't useful. Puncheurs are in their playground on very steep varied gradient climbs where it's everyone for themselves. They aren't as good good on the long steady climbers where the helpers are the most important. The best way D Martin could be used as a help is being there in the final selection and attacking. A puncheur is likely to make a better helper in a sprint train than they will make as a climbing helper.
Both Valverde and Dan Martin are not exclusively puncheurs, but also very good climbers, specially Valverde who during his career won on more than 20 mountain tops.
Valverde is also vey good in mountain ITT's,, so he can pace himself pretty good on the climbs.
Both Valverde and Dan Martin are much, much better as mountain doms than in the sprint train, although Valverde can be very useful there too, but he's a special case.
But let's get back on main topic of this thread.
