Я, безусловно, далек от шоссе. Но даже мне понятно что есть разные направления велосипедов - жесткие модели и комфортные.
Возьмем тот же спеш - (я не знаю кто у кого скопировал) ОНДА от пинарелло, не что иное как вариация виброгасящих вставок (как в теннисных ракетках) - они же Zertz inserts у спеша (например в Рубе).
Но нужны ли они здесь?
Тогда уж и подседел надо брать изогнутый - COBL GOBL-R.
[spoilerдля любителей цифр и дискуссий]Look for the COBL GOBL-R on the S-Works and Pro models. The post was tested under Tom Boonen, who was reportedly skeptical at first but quickly decided it would be part of his setup for 2012 Paris-Roubaix assault.
It’s designed to work in conjunction with the Roubaix frame and remove large vibrations and minor impacts. On the bike, total vertical deflection is 16.61mm/kn versus 13.56 for the 2013 Trek Domane and about 9.5 for the Roubaix SL3. That’s about .67 inches of total vertical flex.
They reiterated that the numbers don’t really tell the story…that it has to be ridden to be appreciated. That said, they still took it to McLaren for testing. Ideally, you have a bike that completely isolates the rider from road vibrations and bumps. Bikes were hooked up to measurement instruments at all contact points, then put a rider on and measured how much of the forces and which frequencies were transferred. With the rider on the saddle, vibrations were reduced by roughly 10% to 20% depending on frequency.
An interesting part of the discussion was that this post would allow Boonen to run higher tire pressure because the post let the bike move under the rider, but the rider wouldn’t move. It goes back to the whole suspend-the-bike-versus-suspend-the-rider argument from the Softride days. Yes, lower tire pressures are good in general, but you run the risk of pinch flats or rim damage if you overcompensate for rough roads. Since you can’t really suspend the bike for road, this post lets you suspend the rider and not have to run dangerously low tire pressures.

От улыбки станет всем светлей и лосю и даже маленькой улитке.
Поделись запаскою своей и она к тебе не раз еще вернется!
Очень красивый!
