What do I need to do to setup my Chainline Correctly? The new ideal chainline for Boost bikes is 51-53mm. From a drivetrain perspective it moves the cassette 3mm away from the frame centerline.

It is now well understood that the ideal 2015 1X trail bike has a 48-50mm chainline.īoost 148 was created to give frame makers more design freedom for tire and front derailleur clearance. XX1 and the similar products that came in the following years had one ring with a 49mm chainline.

The next big change came with SRAM’s release of XX1.

90% of 10-speed bikes sold in 2011-2015 were equipped with a ‘2X spaced’ 104/64 crankset.

Companies returned to 104/64 spiders but with the modern 2mm wider ‘2X spaced’ standard that XX brought.

XX was popular but it wasn’t long before people wanted smaller rings.

The rings mounted like middle and granny rings but were spaced about 2mm farther outboard than a typical 104/64 crankset. XX had a 120/80mm BCD and a 49.5mm chainline.

Enter 2009 and SRAM’s launch of their XX 2x10 system.

All three of these setups shared the same crank spider configuration.

During this time most XC bikes came with triples, freeride bikes had two rings and a bash guard and DH bikes had 1 ring and a chainguide.

Most major crank manufacturers during this time shared this standardized configuration.

The granny ring mounted via its own bolts on a 4 bolt 64mm BCD pattern. The big and middle (or bash and middle) share a 4 bolt/nut combo on a 104mm bolt circle diameter.

Between 20 most mountain bikes had three potential ring mounting positions (big, middle and granny).

Chains that derail when you backpedal while in the largest cassette cog.

Premature wear to chains, chainrings and cassettes.

As such we haven't been conditioned to think about it - That has all changed. This is understandable since before 2009 mountain cranksets were a pretty standardized piece of equipment. Below is a detailed guide to help you get perfect chainline.īicycle chainline is one of the most overlooked aspects of drivetrain setup for 1X systems. At OneUp Components we're 100% focused on 1X drivetrains. This is 3mm wider than the ideal 49mm 1X chainline but makes up the vast majority of all 1X conversions.

Unfortunately, if you were to remove these rings and install a standard narrow-wide ring the resulting 1X chainline would be about 52mm. A 2X crank with tooth centerlines that are located at 45mm (smaller ring) and 53mm (larger ring) would have a 49mm 2X chainline. It gets slightly more difficult if you have multiple front chainrings. For 1X this is easy – If the center of your chainring teeth is 49mm from the centerline of your frame then your chainline is 49mm.

Have you converted your bike to 1X in the past 5 years? If so, your chainline could be causing premature drivetrain wear.įind out how to optimize your setup and save money.Ĭhainline is the distance between the centerline of your frame and the average centerline of your chainring(s).
