Chainring Machining

B&L’s Chainring Machining Service


Make your fixie, commuter, cyclocross or single speed toothless!

We now have the capability to take the teeth off any chainring making it into a chain guard so you can protect your leg or pants on your bicycles.

You can recycle your large chainring in to a functional and nifty piece of art.  Many chainrings have unique designs or a look that is associated with the era they where made.  By reworking them into chainguards you can add a neat feature to your bike that is useful and will make it unique to the machine.

Send or deliver your chainring to

Attention Brice


The cost is 20.00 plus 5.00 shipping , WA state residents include $1.56 in tax per ring

Multiple rings may be combined to save on shipping.

Pay with check, money order or call me and you can use your credit card over the phone.

It is best to make sure the ring you want machined is bigger with the teeth off, than the ring you are using on the drivetrain, this is the reason that the large outer chainring is optimal for this .

Chainrings that are made into chainguards take the place the large chinring .
