This Item no longer available

Below you will find information about an item(s) that BBR no longer manufactures or sells. This information is provided for current owners of these items and for historical purposes. We do not have any more of this item(s) (new, used, scratch-n-dent, or otherwise). We do NOT maintain lists of customers that have these items for sale or that wish to purchase them. All items that BBR currently sells are listed on our Product pages.

Unfortunately, we cannot produce "one-offs" of any of these discontinued items. They were discontinued when we determined that they were no longer profitable to manufacture. Generally, making a single item costs about 10 times the old retail price - or we lose money on it - so we rarely do it. The past 20 years of building playbike performance products has taught us that we need to sell a quantity of about 100, a year, of any particular item for it to break even. So, if you can find 100 people to pay us up front, we'll consider making just about anything. It's that simple.

If you're looking for an item that isn't listed here or on our current Product pages, we also have a more historical section of our website. Check out our detailed BBR Product ID page for lots of photos and general information about BBR products of the past.
