WASP STING SUPER STRONG JUNCTION

Pin-joint rim is out of date! Hold on! This is not exactly right! The new coming “Wasp - Double Pushed Fixing Process
Sting” series will absolutely change conventional views of pin-joint rim.

With traditional round shape steel pin, pin-joint rim gained bicyclists’ reliance on
its stability and strength, however, it also limit possibility on rim design. For example, I. THE PIN - 304 stainless steel pin

balance of the rim. Moreover, using pin which made of different material could risk pin joint rim. Differ from these manufacturers KINLIN adopts

alloy stick can effectively enhance both strength of the seam and the joint itself.
II. THE JOIN PROCESS - Double-Stamped Fixing Process
This unique component provides wide possibilities on designing rims for heavy duty

However loose joint is a common problem in this traditional

result from loose joint causes danger at times. (Please refer
to photo 2.)

Our solution to solve this problem is adopting Double-
Stamped Fixing Process. The first Process is stamping pin’s
end before the rim joined. (Please refer to photo 3.) Second
process is lacing the rim then stamp pins’ end of the other
side. Under this Double-Stamped Fixing Process rim is
3 accurately and firmly joined. (Please refer to photo 4 and 5.)

III. THE ADVANTAGES
3) For Single process pin joint rim, tensile strength of its joint is
around 200kgs, some even less. Rim under Double-Stamped
Fixing Process can uplift tensile strength to or over 600kgs.
This unique process can effectively eliminate weak point of

5) Firm and smooth joint not only provides rim a well-formed
appearance, it also decreased improper wear off that caused
by drop height if joint, and uncontrollable tremble while
applying brake. (Please refer photo 5.)
