Ratio Technologies launches new derailleur upgrade kit <\/p>

Ratio Technologies’ new upgrade enables you to convert your bike to a 1x SRAM XPLR drivetrain without replacing your rear derailleur.\u00a0<\/p>

Instead, you only need to replace the chain and cassette to turn your 33 or 36t max-capacity 12-speed mechanical SRAM AXS road rear derailleur into a 1x-specific XPLR version.\u00a0<\/p>

The upgrade kit enabled you to run up to a 45t cassette \u2013 marginally more generous than SRAM\u2019s 44t capacity.\u00a0\u00a0<\/p>

The Ratio SR45X cage extends the derailleur\u2019s B-knuckle while the cage introduces an offset upper pulley wheel.\u00a0<\/p>

The upgrade kit could also be a good option if you\u2019ve damaged an XPLR derailleur \u2013 SRAM doesn\u2019t currently offer a replacement cage for these derailleurs.\u00a0<\/p>

The SR45X Link will retail for \u00a3104.50 including a link or \u00a394.50 for the cage only (international shipping available).<\/p>

What\u2019s included in the kit?\u00a0<\/h2>

The new cage uses a 12t upper and a larger 14th lower pulley identical in size to those found on Ratio\u2019s cages for SRAM Eagle rear derailleurs.\u00a0<\/p>

The cage includes 7075 aluminium plates and acetal thermoplastic pulleys. These are manufactured in-house by Ratio and assembled with stainless bearings and hardware. <\/p>

You also get a custom stainless steel tool in the kit, which is required to undo the nut that holds the cage onto the derailleur.\u00a0<\/p>

The kit is available in black or silver and is claimed to weigh 66g, or 75g with the link.\u00a0<\/p>

You cannot use an Eagle cassette\u00a0<\/h2>

Ratio Techonlogies says you must use a 12-speed XPLR or an AXS-compatible cassette, such as e*thirteen\u2019s Helix 9-45t<\/a>. <\/p>

This is because the cog spacing differs between SRAM road\/gravel cassettes, and its wider-ranging Eagle mountain bike cassettes.\u00a0<\/p>

Ratio says when you add its SR45X cage and link to a maximum capacity 33t rear derailleur, it not only increases the B-knuckle length to match the XPLR model, but also adds an offset jockey to increase the total capacity to 45t.\u00a0<\/p>

The brand says it did this to help the derailleur\u2019s performance if you\u2019re using an aftermarket cassette, such as the aforementioned e*thirteen option.\u00a0<\/p>

If you\u2019re converting a derailleur with a 36t maximum capacity, Ratio recommends shortening the chain length by two links to swing the derailleur forward and reducing the B-gap.\u00a0<\/p> <\/body><\/html>\n
