BLB Track Chainring 1/8" 130 BCD
Hurry up, only 1 item left in stock.
If you have a complete fixed gear or single speed with a 130 BCD, this is one of the most common types of chainrings you’ll come across. The BLB Track Chainring is a 1/8-inch chainring for 5-arm cranksets with a 130 mm BCD and fits bikes such as the Cinelli Tutto Plus and Gazzetta. A simple way to replace a worn chainring without having to replace the entire crankset.
When the teeth start to become pointed like shark teeth or are clearly worn down, it’s time to replace the chainring. If the chainring has been used for a long time, we recommend checking the chain and rear cog or freewheel at the same time. These components wear together, and a new chainring works considerably better when the rest of the drivetrain isn’t already at the end of its life.
The chainring is made of aluminum alloy, is designed for a 1/8-inch chain, and is available with 46, 47, or 48 teeth. The difference between the sizes is the gearing: 46T gives a slightly easier gear, while 48T provides a little more resistance and speed at the same cadence. 47T sits naturally in between and is often a good way to fine-tune gearing that feels almost right.
The BLB Track Chainring is primarily a good choice when you already have a 130 BCD crankset and want to continue building around it. Compared with the 44T BLB Freestyle Chainring, this one offers larger chainring sizes that are closer to the gearing many riders prefer on a classic fixed gear or track-inspired bike.

Build your custom dream bicycle with us
Consultation meeting
At the first step in the process, we would like to discuss with you what kind of bicycle you are looking for, and what budget you have. It is best if we arrange a meeting for this, either in the shop or online.
Quote
After a paid deposit or purchase of a frame set, we send you a detailed quote. At this stage, there is still every opportunity to adjust the choice of parts.
The bicycle is assembled
Now things are starting to happen! The quote is finalized. We order components and put everything together ahead of the build. Depending on your choice of parts, it takes different amounts of time to assemble the bike, but two weeks from approved quote is usually enough.
The bicycle is ready for delivery
You are welcome to collect your custom bicycle. We also offer shipping to all corners of the world. From our initial meeting, we have taken your measurements so that you sit correctly on the bicycle. Before handing it over, we make small adjustments together with you and, if desired, go through how to adjust and take care of the bicycle. Happy riding! =)
