Trek was the first major brand to introduce ‘Women’s Specific Design’ (WSD) bikes nearly 20 years ago, and the range now covers 15 different road bikes – spanning entry-level to superbike realms – as well as 14 mountain bikes and seven city bikes.
Thanks to the Silque, Trek is ahead of the curve if you’re looking for the smoothest road ride possible – and this Ultegra equipped SL is a particularly strong example of this unique bike.
Perhaps the most remarkable part of this genuinely radical frame is that it’s easy to totally miss the parts that make it unique. Visually the only trace of the ‘IsoSpeed decoupler’ is a small rubber ‘spray deck’ around the junction of the top tube and the seat tube that pierces straight through it. There’s another rubber wrap around the sides and underside of the top tube too and that’s what hides the crucial pivot that pins the two tubes together.
Trek’s unique IsoSpeed technology allows the seatpost to pivot
Yes, we did say pivot. Rather than a standard fixed joint between the vertical and horizontal axis of the frame, the Silque (like it’s Domane unisex equivalent) uses a pivot that lets the seat tube flex back and forth as the bike rattles across rough roads.
