The 2011 Trek Madone 5 Series is virtually the same as last year’s series, except details on where its produced.
Along with the other Madones, the Trek Madone 5 Series is produced in the United States, but the 2011 series is produced in Asia. Because the 5 series is being produced in Asia for 2011, retailers are able to obtain them at a cheaper price, about $1,000 less for a Dura-Ace model, without sacrificing quality.
The Trek 2011 Madone 5 Series features the same round seat mast as the 6 series. This adds for a more compliant bike and reduces some weight.
Throughout the series, Trek uses TCT carbon technology. TCT will go through the whole engineering process as the OCLV carbon. The only difference is TCT is produced in facilities around the world.
Lastly, a BB90 bottom bracket is added, the widest bb on the market. With the BB90, the 2011 Trek 5 Series Madone is lighter, stiffer, and quick to accelerate.
Four models are included in the 2011 Trek Madone 5 series, which are the 5.9 ($3,989.99), 5.5 ($3,779.99), 5.5 WSD ($3,779.99), 5.2 ($3,149.99), 5.2 WSD ($3,149.99), and 5.1 ($2,939.99).
