Pair that with the fact that taller riders are often heavier than shorter riders, and that IsoSpeed technology relies on rider weight to flex the IsoSpeed leaf, and you get a relationship where taller riders have more compliance and shorter riders have less compliance. That's the opposite of what we ideally want. So, the new top tube design isolates the flexing member from the seat tube length, pairing it with a tube that doesn't change length significantly across the size run. ​​​​​​​”</span> </a>由 <a href=""><span style="font-size: 12px;color:black;"></span></a> 授权许可 <span><a href="https://creativecommons.org/licenses/by-nc-nd/4.0/deed.zh" target="_blank" style="font-size: 12px;color:black;">Attribution-NoDerivs-NonCommercial 4.0 International<img src="" style="display: inline-block;height: 16px;width: auto;"></a></span></p>
