The Performer Lacka High Racer 700c Recumbent is a basic, solid, dependable workhorse that will get you where you want to go.
The 11-36t cassette gives you the ability to comfortably climb just about any gradient you are likely to come across. That’s in combination with the 30t chainring. The 11t in combination with the 52t chainring will get you humming along and passing the wedgies at a rate that’ll have them seriously reconsidering the whole upright bike thing.
The Lacka seat is a generously proportioned FRP shell base covered in supportive and comfortable foam.
A great benefit of the Lacka is the the front forks. These forks will allow you to fit either a 26″ or a 700c wheel. This is one difference of the Lacka compared to the Goal 26X which will only take a 26″ wheel.
The 7005 alloy used in the frame is standard aircraft aluminum. Cheaper bike frames are made out of 6061. With 7005 you are getting a lighter frame.
All higher-end aluminum frames use 7005. 6061 is used for stems, handlebars, seat tubes and so forth. The 7005 is better suited for creating a higher quality frame. It comes down to the heat treatment that is essential to creating a safe, lightweight frame.
Essentially, Aluminum is a soft alloy. Steel (eg. Chrome-Moly) is stronger, but heavier of course. Heat treatments are essential for getting a frame “hard” enough so it can perform its job. The first aspect to this is the welding. When aluminum frame tubes are welded together, this makes the area around the weld a lot harder than the rest of the frame. A “T4” heat treatment is required to return the frame to it’s uniform state prior to the T4 treatment.
T6 heat treatment is the next stage. This is necessary to harden and strengthen the frame evenly. For a 7005 frame we proceed with two stages with the frames being air cooled. 6061, in contrast is subject to the one heat treatment and liquid cooled. That brings on rapid cooling and is not appropriate for 7005.
