It eliminated the aero bias of 19mm tires (in fact overall wheel drag on C2 rims with 23mm tires is lower than on our older wheels with 19mm tires). Additionally, 23mm tires have lower rolling resistance, increased cornering capability, and better rider quality than 19mm tires.&lt;/i&gt;&lt;br /&gt;Pero el comportamiento aerodinámico de los modelos Hed para cubierta/clincher (Jet, con llanta de aluminio y carenado de carbono) es bastante diferente de los modelos para tubular (Singer, totalmente de carbono), como se puede apreciar en los gráficos comparativos de la propia marca.&lt;br /&gt;&lt;br /&gt;Por otro lado la idea de neutralizar el par de torsión en presencia de vientos laterales para optimizar el manejo Hed lo anuncia para sus modelos Stinger 2011 (SCT):&lt;br /&gt;&lt;i&gt;Our latest advance is &lt;b&gt;Stability Control Tuning (SCT)&lt;/b&gt;. It is our proprietary design process whereby each rim model is specifically tuned for neutral crosswind handling. What the C2 platform did for speed and cornering, SCT does for handling. The genius of SCT is not simply improved handling – it’s the brilliant handling at no detriment to wheel drag.&lt;/i&gt;&lt;br /&gt;Ambas citas son de http://www.hedcycling.com</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/34232824/5982483538072675372/comments/default/277627628584689207'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/34232824/5982483538072675372/comments/default/277627628584689207'/><link rel='alternate' type='text/html' href='http://www.amtriathlon.com/2010/10/zipp-404-y-808-firecrest.html?showComment=1288648957362#c277627628584689207' title=''/><author><name>Ale Martínez</name><uri>http://www.blogger.com/profile/02557291805073708605</uri><email>noreply@blogger.com</email><gd:extendedProperty xmlns:gd='http://schemas.google.com/g/2005' name='OpenSocialUserId' value='16211510093391718666'/><gd:image xmlns:gd='http://schemas.google.com/g/2005' rel='http://schemas.google.com/g/2005#thumbnail' width='30' height='32' src='http://1.bp.blogspot.com/_dmlilw_lzIU/SwXG3Q9AQTI/AAAAAAAADQY/uCdD0T8xymM/S220/AMFirma.jpg'/></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://www.amtriathlon.com/2010/10/zipp-404-y-808-firecrest.html' ref='tag:blogger.com,1999:blog-34232824.post-5982483538072675372' source='http://www.blogger.com/feeds/34232824/posts/default/5982483538072675372' type='text/html'/><gd:extendedProperty xmlns:gd='http://schemas.google.com/g/2005' name='blogger.itemClass' value='pid-720007458'/></entry><entry><id>tag:blogger.com,1999:blog-34232824.post-6203049604319497390</id><published>2010-11-01T12:54:39.078-03:00</published><updated>2010-11-01T12:54:39.078-03:00</updated><title type='text'>Hola Ale, soy Pepe Salas y quería saber cuál sería...</title><content type='html'>Hola Ale, soy Pepe Salas y quería saber cuál sería la diferencia en tiempo, a igualdad de todos los demás factores, entre hacer 180 km con unas 808 modelo 2010 con banda de frenado de aluminio para clincher, y las 808 2011 firecrest carbon clincher, ya qué la diferencia en precio es sustancial, y hay qué ver sí se justifica la inversión.
