I've got this on my Hybrid Mountain Goat home build. The triple also lets my chain stay more in line with the rear cogs, and keeping my 26t steel chainring means 90% o the time 'Im on the lowest gears, I'm also on steel cogs front and rear which translates to much less wear and tear than climbing on aluminium chainrings or cogs. The idea being that you can get more out of your 1×11 setup, without having to buy an entirely new 12-speed drivetrain. If you ride cross country with some steep hills don't worry about a little bit of weight savings it will save your knees. My Di2 setup takes care of most of the shift effort, so it was just a case of managing the clearance with some added adjustment to the B-tension screw.
Resin pads are fitted out of the box, and they have a nice gentle engagement that makes it easy to modulate the power. I have now gone 1x10 on both my bikes one with a oneup and one with a sunrace cassette , and won't be going back to 2x any time soon. No messing with adjusting the derailleur, B set screws or anything. While Box Components claim its mech is compatible with up to a 46t sprocket, that derailleur did require the use of a longer B-tension screw in order to get the upper jockey wheel to clear the 46t sprocket. Of course a lot of these hills I could normally muscle up and have done exactly that on a 1×10 drivetrain in the past , but as the odometer ticks over and you rack up more miles, that fatigue makes itself more apparent.
I do a ton of climbing on my bike, and as such I tend to wear out the 2-3 largest cogs while the others remain in great condition. You can definitely walk a steep climb faster than pedaling this setup, but those gravity challenged and bad knees folks sure like setups like these. Not only is this putting chain wheels as large as the outer rings on the triples we got rid of years ago its putting 10 tooth jumps back in the mix. For the price I couldn't find anything to match it. Granted, I could try this cassette with a 30T chain ring and this would make using the 37T cog a lot more bearable, but still leave my crawler gear intact. This is the kind of product that has engineers who have no doubt spent years getting a complete drivetrain system to work just so weeping into their cornflakes or morning miso soup. With 2x10, I found I was doing a lot more front derailleur shifting at critical spots on a single track ride.
So far, seems perfectly compatible with my X01 11 speed drivetrain. Negatives At this price, none. Or will cycling the suspension while shifting gears make a difference? The addition weighs very little my bars are de cluttered and I've got a bail out option on long rides. I am running a Shimano chain with this setup. When shifting from 46 back down to 37, there is a small jump as the chain drops, but it is not an issue. It starts with understanding how bike cassettes work. Shimano's 11 x 40 and 11 x 42 cassettes differ by one tooth on the eighth cog position, 27 or 28T , so keep that in mind, as that difference can be felt when shifting to the Xtender's 34-tooth cog.
Garbaruk's three-cog Xtenders don't alter spacing of the first eight Shimano cassette cogs, so it also suits riders who want to enjoy the close-ratio gearing options of the standard Shimano cassette, but with the addition of a couple of stump-puller climbing gears. Problems arose when I back-pedaled the drivetrain while it was shifted in the big, 50-tooth cog - a situation which often caused the chain to jump from the 50 and land somewhere in the middle of the cassette. Shifts better then anything I've ever had. I spin out on my 11t with a 36t front ring when I'm at the bike park quite often. Some manufacturers restrict where we can ship their products. In the 11-42 it runs 24-28-32-37-42, with the 11-46 the same except for the 46 replacing the 42.
I grew in mountains where 800 vertical meters was a norm so I know how to pace myself. Aside from the last shift, all the tooth jumps are 4t or less. Then enjoy 1x simplicity and lightweight. Even if it is slower than walking. Being able to stay seated and calm while twiddling uphill paid itself dividends on those longer rides. When I used it for exactly that purpose on steep climbs it was nothing other than amazing and my legs enjoyed the relative ease of the climb compared to pushing a 42T round.
I don't think this will work on an xd driver - also the advantage of the xd driver is you can have a 10t small cog. The cogs are machined with shifting ramps and angled tooth profiles to assist the rear derailleur, and the overall construction and finish is top notch. In defense of the Xtender, as the steel sprocket teeth started to wear in, I found that I could back-pedal more frequently without risking a jump. That extra bit of range made a difference. Times change, and with the advent of 1×11 and 1×12 gearing systems, range is king. In my head I noticed the difference between how an 11-40 and 11-42 would shift. The ratios are nicely spaced across the range, and the shifting is typically Shimano smooth.
We said they were foolproof cranks, not Flow-foolproof! Shimano's spider assembly has an aluminum 42-tooth, but the weight difference was minimal: Garbaruk's 50-tooth Xtender at 258 grams and Shimano's assembly at 235 grams. Installation was straight forward, and shifting is butter smooth across all 11 including the jump from 37-42 under power. Pinkbike's Take: Garbaruk's 50-tooth Xtender spans the gap that Shimano's existing one-by drivetrains have yet to fill by sufficiently widening the standard gearing range without requiring a different cassette. . Riding with a front derailleur feels like going back in time. Chain did not need lengthening.
Your warranty will be void of course, so bear that in mind if you decide to go down that route. I'm using the 11-46 for my 2005 Trance. All these 'the same' ratios sre to the nearest cog. Very satisfied with my decision. I've got fitter and who said bike riding was supposed to be easy anyway?! You don't have to login or create an account to see shipping charges.
