Evoluzione Cyclesports Quick Release Pins

At last! No more twisting two T25 screws until the wrist aches and their heads are stripped, no more jiggling to get them seated right before tightening them up again, either; and a lot less risk of scratching the paint when removing the seat.

At $25 plus S&H they are overpriced, but so are the OEM screws of which I already had to replace one due to stripped threads. These puppies turn what used to be a three-minute job into mere seconds.

After shopping around, the only place I could find them, that I trust to place an online order with was Sierra BMW. I couldn’t find them cheaper anywhere else either.

The install is simple. Just put some blue thread lock on the pins and screw them in. I used mechanics gloves and just tightened them up with my fingers. Some have suggested to cut a slot into the tip with a rotary tool to make installing and removal easier.

So far, I am happy with the purchase. The pins haven’t worked loose; and the seat doesn’t feel any different to me. The ability to get under there with just a quick “push ‘n’ yank” is well worth the cash I dropped on these.

Let’s see how they hold up on the track next weekend.



Miss Busa Stamp of Approval

Miss Busa Tested & Approved: 4/5

I’m giving this product one heart less for its price point. Also, Evoluzione should update their pins to a slotted design, to make removal easier without risk of damage to the product and make those of us happy who like to torque stuff to proper values.


I will have to amend my review after crash-testing the quick-release pins during racing. They performed up to expectation during a low-speed lowside at about 50 mph; however, when I tucked the front end at about 120+ mph, the seat came off during the bike’s slide into the gravel trap and the battery was ejected. The battery was found hanging off its heavy-gauge ground wire, which kept it from becoming a projectile missile. All other connections had been severed. Fortunately, no damage was done to any electrical and electronic components, and I was able to bend the battery terminals back into serviceable shape. However, it did damage the seat, which is still serviceable though.

I would only recommend these for racing if you have your battery properly secured or are running one of those 2-ounce high-performance cells. I will not change my four-hearts rating, since this failure may have been due to the battery forcing the seat off the pins rather than the seat coming loose and enabling the battery to dislodge. I will, however, properly secure the electrolyte cannon ball before the next race. Securing the battery is a tech requirement for ECTA, but not for WERA. I should have had this done already, regardless. I have the hardware for the project lying around at home. So much for just doing the bare minimum.
