Subject: RE: Weight limits on carbon frames You can call the manufacturer and ask for what load it is 'rated'. For instance, at Bikesport the other day, I learned that Guru load rates their 'standard' carbon bike molds/geometry for 225lbs. Also, make sure you test-ride the bikes - especially going up hills. It's common for us heavier folks to flex the bottom bracket significantly on bikes; to Jim's point, most bikes will likely hold you, but may feel softer than you'd like - it's personal preference at this point. Again, using the Guru as the example, the Guru folks have a different carbon mold that uses more carbon, especially around the bottom bracket, to stiffen it up for the 225lbs+ crowd. Lastly, a good LBS will be able to advise you on which manufacturers use additional material in their BB and downtube - adding stiffness to accommodate us. |
