Final January I handled myself to a seventieth birthday current of a brand new seat for my recumbent. Sadly as a consequence of supply-chain points, it ended up back-ordered, and I simply obtained it.
This seat is doubtlessly extra comfy as a result of it will possibly recline extra. It additionally needs to be extra aerodynamic. The primary goal of the brand new seat is consolation, not aerodynamics, so I’ll get good use out of it. However being a retired engineer, my inside nerd was curious in regards to the potential velocity benefit.
The seat on the left was the unique seat, known as the “recurve”. The one on the best is known as the “Euromesh”. There’s a restrict to reclining on the recurve as a result of it makes the entrance stick up too far and whack into the again of your legs. This isn’t a difficulty on the Euromesh due to its form. The 2 are proven facet by facet with the usual incline.
You’ll be able to see there may be heaps extra room to decrease the Euromesh. I attempted out the brand new seat with it reclined a number of extra inches than the recurve. I did a velocity trial on certainly one of my commonplace Strava routes, the Coyote Creek path to Bailey Ave and again. Surprisingly, I used to be a couple of minutes slower than my greatest time. It felt like I couldn’t put out as a lot energy. I can push actually arduous on the seat again of the recurve when going quick, however on the Euromesh it felt like I might waste some power sliding on the seat.
Skilled cyclists on standard bikes have additionally run right into a trade-off between being extra aero and the flexibility to place out energy. However I hadn’t heard of this on recumbents. I do know that every one the velocity information on recumbents are set on very reclined seats.
I’m cussed and wasn’t prepared to surrender. It turned out that the size of the stays holding up the seat within the again prevented reclining so far as I needed to strive, even when telescoped to the shortest size. I didn’t wish to minimize the stays as a result of that will make them unsuitable for the opposite seat. So I kludged collectively short-term stays utilizing dowels. If this had labored I may have made it extra official by shopping for some tubing. The “prototype” is proven under.
This place is much more aerodynamic however would take some getting used to comfort-wise. I attempted doing a little brief sprints with it to check velocity, and once more, surprisingly, it was not any quicker. However this additionally may need been as a result of pedaling felt extra awkward. This can be only a matter of getting used to the brand new place and adjusting my pedaling model.
