Terpstra winning on a Roubaix
The difference between Terpstra’s bike and the Roubaix SL4 I’ve been riding in the rain, since the Fall, is Force 22 instead of the Red 22 spec. When raced or ridden hard, the fenders are removed and the fast, Zipp Firecrests replace the 30s. Force is SRAM’s value group, with all the features of Red, at a more affordable price. When asked recently about it, I said, if I close my eyes and don’t look at the graphics it shifts just like Red.

Between the two, there’s about a $3K price difference. Terpstra’s race-winning Roubaix is around $9K and my parking-lot crit, rolling-a-fondo version is $6K.
