Ratio Announces a UK-Made Lightweight Derailleur Cage for GX AXS £89.50

Ratio Technology, known for its shifter upgrade kits and UK-made components, today launched a derailleur cage for Eagle AXS derailleurs. Machined from 7075 aluminum, the new cage shares many features with its mechanical-shifting cousin but has updated geometry for compatibility with SRAM’s electronic MTB derailleurs.

The new cage features 14t and 12t jockeys running on stainless Enduro bearings and held together with full stainless hardware. The standout feature of the cage is its weight: At 79g out of the box, a Ratio cage saves 67g over GX AXS and 5g over X01 AXS. The cage aside, SRAM’s electronic derailleurs are all virtually identical in their construction. The result is that a GX AXS derailleur fitted with Ratio’s cage weighs the same – but costs less – than SRAM’s X01 model.

Additionally, the new cage fits on all of SRAM’s Eagle AXS derailleurs, making it a replacement part that they don’t offer. Bending or breaking a cage should not write off a derailleur that could have cost you over £550/$750/830€, and now it won’t.


  • Compatible with all SRAM Eagle AXS derailleurs
  • 7075 aluminium cage plates, CNC machined by Ratio in the Lakes
  • Delrin jockey wheels for smooth, quiet running, CNC machined by Ratio in the Lakes
  • Stainless Enduro jockey wheel bearings with labyrinth seals
  • Stainless cage hardware
  • Cage weight: 79g (SRAM GX AXS 144g)
  • Pricing: £89.50 inc. VAT / USD $91.50 / EUR 84.30€ / AUD $131.50

Sinewave Cycles Beacon 2.0 Pre-Order $350

We’ve been using the Sinewave Beacon since its initial launch and can’t recommend it enough. While there were a few quirks, overall, we’ve been pleased with its performance. Yet, for the past year or so, Bailey from Sincere Cycles has been riding with the Beacon 2.0 and it’s a huge improvement. More on that later. The most notable change is the flicker-free light down to 3-4 MPH, which means your light won’t be strobing as you’re climbing that singletrack anymore. It also features a symmetrical beam pattern now and the dynamo power is optimized at low-to-medium speeds, reaching 100 lumens at 5 MPH, 375 lumens at 8 MPH, 600 lumens at 10 MPH, and 750 lumens at 13 MPH. What we’re saying is the Beacon 2.0 is dialed in for singletrack riding more now than ever.

Sinewave is taking $50 deposits now, which goes towards the $350 retail price when they ship in Spring/Summer 2023.

Thumbster: A Modern Bicycle Thumb Shifter on Kickstarter

We got served this on our Instagram explore page this weekend. Ain’t it nice when you get shown things you actually like?

Here’s something for the garage tinkerers, the Rivendell savants, the vintage basket bike builders. Thumbster is a new thumb shifter, designed in Japan and manufactured in Taiwan. The Thumbster embraces the 1x trend of basket bikes, or everyday bikes as Thumbster calls them, and only offers a rear mech shifter, which is kind of a bummer in our opinion, but plenty of people convert their bikes to 1x as its often used as a city bike. At any rate, we love seeing this kind of product design, so roll on over to the Thumbster Kickstarter to see more.
