Looking to go 1x10 or 1x11 on my Trek X-Caliber

I've had my Trek x-cal 7 for a few years now (2015 model) and haven't done any mods at all. I'm looking to change things up and thought about ditching the 3x9 for a 1x10 or 1x11. I'm not sure if one is better or not possible etc.

With the trails I'm local to I think it would be fun and I can ditch some weight and clean up the look.

I did a few searches and never really landed on a thread that was a dummy guide. I visited my LBS and they just wanted to sell me a new bike so that wasn't helpful.

Is this just as simple as buying a new group set? Or is there some things I need to do differently based on what my bike currently has (Acera 3x9).

Thanks for the help!

Should not be very difficult.

I'd start here...

Shimano Deore 1x10sp Gear Kit Bundle | Chain Reaction Cycles

You'll need at minimum a chainring, derailleur, shifter, cassette and chain. You could change your crank, but depending on what it is, 3X actually work well (I like them the best for chainline actually). Mount the 1x ring in the middle chainring position for best results.

You can probably reuse your rear derailleur housing and cable if you are careful.

I'd stick with Deore. It's cheap and it works great. I have one bike running all Deore but the cassette and it's a champ. The cassettes are OK too though.

Gearing definitely go for a 11-36 cassette and a 30 or 32 T chainring, depending how strong you are. If you do a lot of road riding, go bigger, like 34 or 36 but be prepared for some hard climbing. I like 30 up front for a trail bike with 29" wheels.

If you don't have access to bike shop tools, then you'll need the cassette nut tool and a chain whip to change the cassette. Everything else can be done with allen keys and pliers except maybe removing the crank and chainrings, that will depend on what you have. Oh and you'll also likely need a chain tool if you don't have one.

Besides needing the tools its insanely easy. So no real guide needed its only 5 parts. Cassette, shifter, rear derailluer, chain, and narrowwide chainring.

1x10 vs 1x11 the price difference isnt huge. Dont HAVE to change the cranks, just remove the chain rings and replace with a single narrow wide ring (they work for 10 and 11 so doesnt matter there)

You need to know what gears you ride in on the back the most and what rings you use up front. Thing is youll loose some range (top end).

1x10 get shimano zee system which is just the shifter and rear derailluer. Its cheap and better than deore. Cassette at minimum 11-36. 11-40 or 11-42 if you need lower gearing.

If you have the funds it costs under $200 to go 1x11. Get shimano SLX m7000 11 speed shifter, rear derailluer and 11-46 cassette. And whatever narrowwide chainring you want.

11 speed is a bit more range so you can run a bigger ring up front if you need more speed.

Umm... looking at your bike spec, you already have a 11-36 cassette.

You could simply just put a NW ring on the front and remove the front derailleur and shifter... off you go.

Specs say your bike has a 44/32/22 gearset up front. Can you ride everything in the middle ring? Do you need that 22, and if so, all the way down to the 22/36? If so, then 1X is not a good idea. If the 32 seems just a bit too much, a 30 1X up front will probably be the ticket. Like $50 for a RF... done...

If you use that 22, then you'll want to look at expanded cassettes. You can get them from Sunrace for 9spd, which would simplify your upgrade.

A couple pictures of a 30 tooth raceface single installed on my wife's Trek with a 3X crank.

The 30T doesn't use a nut and the chainring bolt threads right into the ring, which is threaded. You may want to buy the shims (black pieces on the outside) or a bashring but I think it will work without (depends on your bolt lengths.

You'll need to break the chain (best to get some master pliers and split it there), remove the crank (I think yours may be a Hollowtech, and they are super easy to remove - check youtube and buy the bit to set the preload). Remove all the old rings, and put the RF ring on there with the step facing the crank arm.

You'll likely want to remove a few links from your chain, so a chain tool will be handy for that. Go slow and don't do too many, adding back is much harder and require two masters or a new chain! The idea is to get the cage on the derailleur so it has very little movement in the biggest cog. Too tight and it will shift poorly into that gear. Honestly you could leave the chain as it is, but it will shift better if you optimize it for the single ring.

A single chainring and an 11-36 cassette is a fairly narrow overall range. There could be rides and riders that will be OK with that, but I would not recommend it unless you know it fits you and your riding trails/style.

If you have an 11-36 cassette and a 32t chainring already, try riding EXCLUSIVELY with this combination for a few rides and know for certain that it will be OK for you. Even if you middle ring 95% of the time, that 5% might be mission-critical.

OP, I am currently doing that same upgrade on my Rush. My LBS quoted the following:

Drivetrain Option 1 Shimano XT 1x11 $325

Shimano XT Cassette
Shimano XT Rear Derailleur
Shimano XT Shifter
Shimano XT Chain
RaceFace NarrowWide Chainring

Drivetrain Option 2 Shimano SLX 1x11 $255

Shimano SLX Cassette
Shimano SLX Rear Derailleur
Shimnao SLX Shifter
Shimano XT Chain
RaceFace NarrowWide Chainring

Labor for Full Suspension Tune $160

Includes suspension rebuild, bearing adjustment, new drivetrain install, brake adjust, new cable and housing etc



I am leaning towards the XT version for the weight savings and additional bearings (instead of bushings).

As others have stated a new rear cassette at 11-40 (or larger) will be the difference on the longer or more technical climbs. I may even go for the 11-42.
 
#13 ·
Where are you pricing your m7000??

Cassette is 60, shifter 30, derailluer 50, chain 30 anywhere online. $170 before tax

Full XT is barely over $200 before tax.

Weight savings is minimal accept cassette. Im running m7000 with an m8000 shifter and sunrace 11-46 cassette and was still a hair under $200 to my door.

I started looking at doing the SLX group. I think I might go that route. I have two questions left....

1. For the shifter mount. Do I want bar or I-Spec (B or II)?

2. Do I need a new BB for the SLX crankset? I'm curious if my existing would work ok.

Still looking for suggestions on retailers.

1 - if you have bar clamps currently, you probably want to stick with that.

2 - if your crank is a hollowtec II, then the BB should work fine. Most cranksets from Shimano come with BBs though.

Well. I got my plan in place. Thank you for everyone that posted above w/ really detailed information. I've learned a lot from each post for sure. Really, no option mentioned above was wrong and I considered each one but ended up ordering an SLX setup.

I'm excited to have a chance to really wrench on the bike now. Granted I probably could have sold it, bought a new bike, etc. but would lose out on the tinker factor and making it a learning experience.

My next research topic are tires!
 
#18 ·
Hopefully you bought the tools you need. Chain whip, cassette lockring tool and crank/bb tools.

Thing about tools is they are something youll use forever, bike after bike, so its not a wasted investment. Neither is doing some upgrading to your current bike, knowledge is priceless.

So true. I have a cheapo bike tool kit I bought over 14 years ago and it is still going strong. I have had to add some tools as bike components change but it has never let me down.

Haven't calculated yet. I did find it was cheaper to buy the group set separately versus going with a bundle from some of the sites. It was maybe $50-$70 cheaper by buying from 2-3 different sources. I got the majority from Jensen though.

chain reaction had it for $315ish. I think it was $250 ish from shopping around. Plus, I got a better chain than what was included too. So, apples to apples to Chain Reaction was maybe $315 to $239. I also got a new BB so that's another $18. Tools maybe $50 or so. I had nothing. I'll run the numbers in the next week and recap it all. I'm probably around $300 for everything including tools and the BB. I'll try and flip my existing group set on eBay too and see if it's worth anything. Maybe worth keeping in a box in the garage. Who knows.

You will be losing a lot of range just to save a minimal amount of weight and ''looks''.
Giving up ability is something I would put some thought into.

I know 1x is new and cool and all but it is not for everyone and certainly not an upgrade. Unless you are specifically using the bike for racing where every gram matters and limited range is enough to finish a race it is a downgrade.
 
#24 ·
I'd say SLX 11-speed is an upgrade over Acera 9-speed. 1x vs. 3x is a different issue but for a lot of riders that can be an upgrade too and not because of the weight. For a lot of people and trail conditions 1x gearing range isn't the least bit limiting.

12 speed pretty much matches 2x range and 11 speed isn't that far off when you consider that most riders don't use the whole range on multi-chainring drivetrains anyway, especially with 3x, 1x can make a lot of sense.
 
#25 ·
All good points. I think a lot depends on your local trails. For me. I've had the bike 100% stock for a few years. I figured I would try a different setup and see what the experience is like. I'm also pumped to get a better level than the Acera. Although it never gave me issues.
 
#26 ·
You'd be surprised how little difference there is in the Shimano groupsets besides overall weight. I'm not all that familiar with Acera, but Deore, SLX and XT are nothing to write home about in differences, especially for 1X. The biggest differences were actually in the front derailleur and chainrings, the XT being the best shifting. The instant and dual release on the XT shifters is nice, but to be honest, my Deore shifter works better (especially on upshifts).

The major downfall of 9spd for 1x is lack of a clutch derailleur. It's something I consider a must now having lost chains with 1x using NW rings. Even more aggressive riders will want a chain guide in addition.

1X makes a lot more sense if you run a dropper and/or lock because it frees up your left hand for those things. And if you are a rider who using a dropper a lot during the ride, it's nice to have it an easy to use location.

I think a lot of people put too much emphasis on range in MTB. How often are you spinning out a 30x11? I only can spin out a 36x11 with cross tires on my bike, and they are quite a bit smaller diameter than what are standard MTB tires now.

Bigger front rings have advantages if you actually use that range and are primarily riding on the road, but in that cases, unless you are really strong, you probably don't have a lot of big hills.

A lot of 1x really comes down to picking the right front ring. That's all there is to it. If you are really pushing 36/38x11/10, and need ultra-low 22x42 for climbing, then stick with 2x. If not, your bike has way more range than it needs.
 
#27 ·

Agreed, pretty much never spin out 30x11 on the trail but range is still a big consideration IMO. 30x11 is a good top gear for most but if you use 9-speed you'd be limited to a 24 inch low which is pretty stiff for lots of people and terrain. Yes you can get bigger aftermarket cassette cogs but at that point I think 11 or 12 speed opens a lot more options and will perform better with wide range cassettes. Again, required range is rider and terrain dependent. Some only need 1 gear.

Acera is pretty low rent with lots of flexy plastic, it work's ok but SLX is much better under demanding conditions IME.

I ended up with a 32 front and 11Ă—42 rear. This will provide all the gears I need for my local trails (tight single track). I never use the big ring and seldom use the small.
I needed a new drive train anyway (8 yeara old) and like the advantages of the 1X. Especially the higher clearance as the Rush had a low BB anyway.
LBS said he can do complete package at a lower price (I will let everyone know) and it should be done this Wednesday.

Good thread. I decided to go 1x9 on my 2012 Fuel EX-9 since I am always in the middle chain ring anyway. Bike had 22-32-42. I replaced the cassette last year with a Shimano CS-HG400 12-36 cassette for better climbing. I will be getting a 30t ring up front. Should gain a little better climbing and not loose much at all for descends and flats. Looking forward to cleaning up my bars, dropping a tad bit of weight and putting a southpaw lever for my dropper where the shifter was.
 
#30 ·
I happened to have a bank error in my favor so this thread enticed me to throw a 11spd SLX on my rigid bike. I really do need more range on that bad boy.

Not too bad on the price:

Cassette $53
Chain $29
Shifter $29.50
Derailleur $51

Basically gives me all the same gears I'm running now with my 11-36 but with a 42t granny... oh my knees will thank me!

Checked out all the other options for expanders but no way I'd mess with my 17 and 15 cogs, I use those the most on the asphalt.

I just went to a 1x11 on my '91 RockHopper. It was more expensive than I anticipated (I suck at having patience to work on drivetrain), but not nearly as expensive as having the Rockhopper as a SS just hanging on the wall due to the pain of climbing without a granny gear. After using for first time this past weekend, I can't imagine having the need for 3 rings up front ever again with the trails I'm riding in WNC....no regrets at all!
 
#32 · (Edited)
First ride with the new 1x11. Like a different bike.
The good:

Always felt I was in the right gear, since it was so easy to go full range. Shifting was precise but definitely different and will take a while to get used to. Also I didn't know what to do with my left hand without the levers over there to fidget with while climbing.

Cleared a log crossing I have never done before. It was weird because I "braced for impact, thinking the big ring would catch" but it never bottomed out and just glided over.

On my trails 32x11 is more than fast enough.

Never heard chain slap even on fast rough sections.

The bad:
Wore me out more than any other ride this season. I can no longer drop to granny and sit and spin it out. I now will have to atrack the hills like I do on the road bike. (This may end up being a good thing though)

So. I got the 1x11 setup installed. Couple wonky issues. I can't get the b screw adjusted where the wheel is close enough to catch significantly on the 42t. Not a huge deal though. Other issue is that I can't back pedal on the 42 without dropping down to the 37. What should I try adjusting?

I don't understand what you mean? The guide wheel shouldn't catch on the 42, there should be like 5mm of clearance there.

These offset pulleys are a little harder to adjust because your chain length affects your B tension adjustment. My advice is to get the chain length right, then adjust the B screw until you have proper clearance in the 42. I'd say mine, on a SLX 1x11 is right about 1/3 of the way in.

The backpedal issue is chainline. I'd forget it. Do you plan on doing a lot of backpedaling in that gear? If you do, you need to file the teeth on the 42 or shim your BB or chainring.
