The handle section of the SS-7, because it is the most likely to be damaged in a fall, is made of cold forged aluminum. The handlebar clamp section is melt forged aluminum. The handle section is held to the clamp assembly using the same steel bolt found on the SS-5 levers. Made of steel, with a conical shape to recess the head, the bolt has a 4mm hex fitting and 5mm by .8mm threads. It anchors into an 8mm outer hex, cadmium steel nut on the bottom of the clamp section to hold both sections together. A nylon washer on the top and another on the bottom of the lever with the connecting bolt passing through them reduces friction as the lever is used. The return spring in the SS-7 is different from that in the SS-5. The SS-7 uses a small in diameter coiled spring like the type used to retract the ink cartridge in a ball point pen. (The one used in the SS-5 was coiled, but 13mm in diameter and coiled around the connecting bolt and washer assembly.) The SS-7 spring has a small nylon tip on it so the steel doesn't bind against the aluminum as it is worked.
The brake lever fastening bolt clamping the SS-7 to the handlebar is the same used in the SS-5. It has 6mm by 1mm threads, a 5mm hex fitting, a 18mm length and a 4.5 gram weight. The SS-7 uses the same cable barrel adjuster set found on the SS-5 levers. The handle has a 95mm length from the bolt holding it to the clamp section to it s tip. The area for finger contact is 65mm long. The SS-7 has a small steel set screw with a 2mm hex fitting that is used to adjust the «throw» (or how far the handle springs forward to close once it's been released) of the lever. Like the SS-5 levers, tightening this screw shortens the distance the handle can travel when released making it easier for a small hand to use. There are two recessed holes in the clamp section, that appear to be there only to reduce weight. The handle piece of the SS-7 can come in any of 4 colors, Blue, Black, Lavender, or Titanium Grey. The Clamp section is always Black. The pair weight of the SS-7 levers, complete is 179.5 grams. Made in Japan.
