The majority of drivetrain innovations are focused on adding cogs to cassettes and incremental improvements to shift performance, but a Canadian mechanical engineer has a radical take on derailleur design that might be a sign of things to come. Cedric Eveleigh spent the last two years...

Hello all, got a question and wondering what your thoughts are on the matter. I purchased an AXS Eagle derailleur and shifter brand new back in May (4 months ago). They have been working flawlessly as all the glowing reviews indicate they should. This past week, I started having gear trouble in...

I live in an area were all the trails are rather sandy... but it's a fine silt in the mud, rather than your average 'desert sand.' Even a dry gravelly ride kicks up plenty of this silt into my chain. Now, making a chain 'clean' isn't rocket science, and it's certainly no issue to get the chain...

Hi all, I have this super annoying chain drop that happens once or twice nearly every ride. It occasionally happens when I am on the lowest gear and climbing, but it most frequently happens when I am shifting between my lowest and second lowest gear while climbing. It seems to have some sort of...

Adding versatility to its drivetrain lineup, Shimano introduces its new LINKGLIDE technology, designed and engineered to increase drivetrain durability while further enhancing the seamless shifting that Shimano is renowned for. LINKGLIDE components offer a more robust drivetrain option for a...

I’ve recently been thinking about upgrading my 3x7 drivetrain. I’ve had a go at trying to make it a 1x7 as I’ve already taken the front Derailleur off and now the chain just sits on the 2nd front gear. I’ve tried to seperate the front cranks but it appears that they are fixed together so I can’t...

Hey, I just had a very big accident about a year ago and my right hand was compromised, and just now they are letting me ride bikes again. Since I sold my old nomad, I'm searching for a new bike, but since i can barely use my right hand (just for holding to the handlebars) I'm moving everything...

Hi all, I have done lots of research but am still in a toss up. I have two things. 1. I am currently running a Santa Cruz Matte Carbon 5010. My frame has some gunk from the chain and some other patches of grease or other stuff around the frame. I tried cleaning with dawn dish soap but it...

Hey folks I’m doing a refurb of an old Kona Coiler I have for a friends son to ride and I’m thinking about whether to / how to do a 1x10/11 set up on it. It has a shimano hub so no problem there and getting a narrow wide chain ring won’t be an issue either. the problem I have is the hanger...

I'm going to be upgrading my 2x10 drivetrain to a Shimano XT 1x12. While my current crankset's Q-Factor is 175mm and the chainline is 48.8mm, the Shimano XT 1x12 has a Q-Factor of 172mm and the chainline is 52mm. What, if any, affect will this have on my bike? I'm primarily riding slow tech...

Finally… let the mountain bike drivetrain war begin anew. After spending several years off the back of the 12-speed-wide range-1x race, Shimano can stand shifter to shifter with SRAM, following today's launch of new XT and SLX groupsets. Yes, we know that 12-speed XTR was announced last...

While the launch of 12-speed Shimano XTR and then XT will likely garner more immediate consumer interest, it's the new SLX group that's arguably the most important new entrant into the mountain bike component world. Like SRAM's popular Eagle GX group, SLX will deliver wide range gearing (and...

Though it was a very small sample size, Shimano's new XTR appears to be just what you would expect - awesome. Photo courtesy Shimano/Sterling Lorence What is it Shimano's first foray into the 12-speed mountain bike drivetrain world, the new XTR M9100 group is a ground-up redesign that aims to...

Greg Trash shows us the upgrade process The pitch You just upgraded to 11-speed and it seems the bike world has made your system obsolete with the proliferation of 12-speed Eagle. You want to try out this new-fangled drivetrain with 500% gear range but are not really excited about throwing...

Complete NX Eagle group shown here. 1x gearing is one of the greatest revolutions in mountain biking with a drivetrain perfectly suited for the demands of the sport. A knock against it was range but SRAM Eagle with its 10-50t range addressed most of those concerns. Of course price was a concern...

SRAM GX Eagle; takes a kicking and keeps on shifting. Winter; when roads covered in ice mixed with salt, is frequented by crazies on bikes looking for fresh air. Conditions like these are not great for metal grinding on metal, ie, your bike's drivetrain. During these wet seasons, we run our...

Mtbr's been testing the new SRAM GX Eagle group on this Santa Cruz Hightower. SRAM Eagle 1x12 was introduced last year amidst much anticipation (and some skepticism). But the near unanimous feedback from everyone who's tried it has been a resounding thumbs up, aside from some complaints about...

SRAM's EX1 drivetrain is highlighted by the 11-48 8-speed cassette with 30% jumps between gears. Lowdown: SRAM EX1 E-Bike Drivetrain The e-bike market for commuting and trail riding is growing at a rapid pace and new motor systems and frames designed for the task are being introduced every few...

Our tester Santa Cruz Hightower looking good in plus and Eagle garb. Lowdown: SRAM Eagle 1x12 Drivetrain At this point we've all grown a little tired of new mountain bike standards, but just like disc brakes and tubeless tires, if it proves its benefit the tribe embraces it. This is the key...

The new GH DX drivetrain brings SRAM's premiere gravity 1x technology to a price point even park rats can afford (click to enlarge). If there's one style of bike where durability and strength trump all other factors, it's downhilling. These rocketships are designed with one purpose in mind...
