TRW Active - Who we are
High quality durable components at an affordable price.

TRW Active was born in Los Alamos, New Mexico, in the mountains and desert of the southwest US. We are engineers by trade, but more importantly we are riders, and we ride the components we develop. The TRW-2 mountain bike drivetrain components have been in real world testing for the last year and a half, and are now ready for launch to the public. All of the R&D is complete, and we have manufacturing partners with the capacity to fulfill orders. We even have our first 150 production units in house ready to ship to the first supporters. We are launching TRW Active on Indiegogo, a crowdsourcing platform, but we have already done the work so you can enjoy the products. For the next 60 days we will be selling our components at a discount, to spread the word and build up the brand. We sincerely hope you enjoy riding on the components we make, and we stand behind them with a great warranty and product support.
Wide-range 1x11 drivetrain that fits existing wheelsets!
Affordable state of the art mountain bike components designed to upgrade your existing multi-chainring 9, 10, or 11 speed drivetrain to 1x11. Or build up a fresh new bike with ultra-wide range gearing.
The TRW-2 groupset features an 11 speed 11x50 tooth wide range cassette, or an optional 11x52 tooth ultra-wide range cassette. The crankset accommodates direct mount chainrings from 28t to 38t in standard and boost offset, and 165mm, 170mm, or 175mm arm lengths. The rear shifter is an 11 speed dual release trigger design that allows for down shifting with either the index finger or thumb, as well as 5 gears in 1 sweep with the thumb lever. The rear derailleur comes in either a medium cage, or a long cage, low profile design. It features a clutch, to ward off chain slap, and a lockup switch for easy wheel removal and installation.
TRW-2 11 Speed Shifter
The TRW-2 rear trigger shifter is a modern high performance mountain bike shift lever.
It features a dual-release trigger, actuated by the index finger, that can either be pushed or pulled to shift to the next harder gear. The thumb lever is forged aluminum, and allows for up to 5 gear selections in a single sweep. Perfect for those hard G-outs into a steep climb when you need to shift multiple gears. The shift levers ride on sealed cartridge bearings, for precise shifting, and provide many rides worth of reliable actuations. It matches up perfectly to our TRW-2 rear derailleur, but is compatible with other 11 speed rear derailleurs and cassettes on the market.

TRW-2 Rear Derailleur

TRW-2 Rear Derailleur
A modern high performance wide-range rear derailleur w/ clutch and lockup switch.
The TRW-2 rear derailleur is a high performance gear changer that can accommodate our new wide range cassettes. 3D cold-forged from high strength alloy, it is designed for the most demanding riding conditions. It features an adjustable clutch mechanism, to ward off chain slap, and a lockup switch to aid in removing and installing the rear wheel. It comes in medium and long cage formats to fit cassettes ranging from 11-42t, all the way to our extended 11-52t. The TRW-2 derailleur is also very low profile to help avoid rock strikes while riding in rough terrain.
TRW Cranksets
Strong and light 1x cranksets in HD for Enduro/DH and LW for Trail/Racing.
TRW cranksets come in two varieties of 1x direct mount chainring profiles. The first is the HD crankset, and it is designed for Downhill and Enduro use. It is 3D cold forged with a steel 24mm spindle and reinforcing ribs. The second crankset is the LW crankset designed for trail use and racing. It is lighter weight with the same 3D cold forged alloy, but a wider and thinner profile. Both cranksets feature direct spiderless chainring mounting for standard and boost rings. The cranks also feature an adjustable tension bolt to remove play from the bottom bracket and a secure opposeable bolt pattern on the crank arm.
TRW Active light and strong wide range cassettes w/ alloy carriers and forged cogs.
TRW Cassettes come in sizes ranging from 11-46 to 11-50 tooth, and an extended range 11-52 tooth profile. They are made with high strength forged steel and alloy cogs riding on a forged alloy carrier. The cogs are coated for wear resistance and long running performance. They feature ramped profiles for smooth shifting and even spacing between cogs. Our 11 speed cassettes are compatible with other manufacturers' shifters and derailleurs. They fit on standard style 9/10/11 speed freehub bodies.
