What’s better than Trek’s Madone SLR? How about a Madone SLR that’s lighter? Or one with a different bottom bracket? If either of those sound good to you, then you’ll want to check out the 2021 Madone SLR.
The SLR addition to the Madone name gives the indication that this isn’t your average Trek. In this case, the SLR moniker implies that this is the lighter race version of the 2021 Madone which relies on OCLV 800 Series carbon fiber to cut weight – a boost from the OCLV 700 used on the 2020 model. Not only is it lighter, but Trek’s 800 Series carbon claims to be their highest performing carbon layup ever – resulting in a laminate that is 30% stronger and just as stiff. The frame itself is said to be 80g lighter thanks to the change in material.
Not light enough? You can also spec your Madone SLR through Project One just like team Trek-Segafredo would. Compared to the 2019 spec, the 2020 spec comes in at 450g lighter. That breaks down to 80g for the frame, 100g for the RSL 37 wheels, 160g for the Aeolus 1pc bar/stem, 50g for the Lightweight P1 Select Paint Scheme, and 60g for the new BB.
Yes, that would be a new T47 bottom bracket which seems to be slowly taking over Trek’s bottom bracket duties on new bikes.
Note that the 2021 rim brake Madone SLR frameset still uses BB90 however.
Otherwise, all of the 2021 Madone SLR models use disc brakes. Available in 6, 7, and 9 model levels, there are also two versions of both the 7 & 9 levels with standard or eTap builds. Pricing starts at $6,899.99 for the SLR 6, and tops out at $12,499.99 for either the SLR 9 or SLR 9 eTap.
That is of course, until you get into Project One builds which have the potential of even higher prices depending on your selected finish and build.
