Good day everyone!

I'm plannig to convert my actual Meta v4.2 TR into the All Mountain version, in short go from 130 mm rear suspension to 160 mm. I'm very very happy with the bike and its parts, just thinking I need more travel as I'm getting more aggresive, and don't want to spend money on a new bike. 8)

I don't know anyone with the v4.2 am version to check the measures, but I've checked the commencal tech webpage, and seems that every piece, despite the shock and fork are exactly the same between versions. Also the geometrie numbers not affected by the fork length are the same.

So for my seems extrange but could be possilble than the only difference is the shock, going from a 210x50 to a 230x60?

I also made a 'Paint' comparison, and the frame 'looks' the same, just having the seatstays a little bit farther back (green line in the picture). The yellow and blue lines centers the bottom bracket and shock link on the top tube on both images (extracted from commencal tech).

Commencal Meta v4.2 TR and AM comparison

Thank you so much in advance for helping me with this! Wink

i think this would be an excellent question to ask Commencal. I know they sell linkages for both bikes right on their site - i wouldn't go for it without at least asking the manufacturer

I think it would be okay. Have been looking at the same thing for the 2020 version. The tr and am seem to have the same frame every year.

If you end up digging into this project, note that the rocker link (that black linkage component) is frequently upgraded on the Meta AM / TR to the link used on the Meta Power. Would be worth considering if you're going to be taking bigger hits.

I know, I’m a bit late to this, but this is not possible. The front shock mounts on any am frame is moved forwards compared to the tr frame, so a new rocker link wouldn’t do anything. Depending on what shock stroke you’re running, you could go to a 210x55 and get ≈143mm and put a 160mm fork on there, and the bike will rip. And if you still want the bike to feel more aggressive after that, beefier tires, and stronger brakes will help a lot.

Hello, just wondering if anyone made any alterations in the end? I am in the same boat with the 2019 meta TR. Swapping the 140 spring to a 160 in the revelation seems like an easy win. Just wondering if anyone had done this and how it affected the ride? Thanks

I put a 150mm cartridge in my fork on a 2019 meta tr and it is a great upgrade, also a 1.5 degree angle set.
Has anyone put a 27.5 back wheel on? And how did they go about keep the bottom bracket height ?

Hey- Bringing this back up. I love my 2019 Meta TR 29. I currently have the fork at 150 Wondering if anybody is running theirs at 160 and if so is it noticeably better? I'm also thinking to lengthen the stroke of the shock to 210X55 for the extra travel out back.

Other things I'd be interested in considering if people have tried them, Angle adjust headset? maybe dropping 1 degree, reach adjust headset, I wouldn't mind lengthening my reach 5mm, I know the angle adjust headset would actually shorten my effective reach as would a 160 fork.

Any thoughts?

I did this after seeing your post @adien700 and previously upgraded to the power linkage after the stock one fell into 2 bits when I serviced the rear shock

Upgrades on 2017 tr v4.2 essential

2021 Lyrik 160mm fork
2021 Rockshox deluxe 210x55
Stans mk 4 flow with hope hubs (folded the front Mavic rim )
Power linkage
Sram Code brakes
180mm front 160mm rear disks
Magic Mary super trail front with insert
Hans Dampf enduro rear (couldn't get the tyre on with insert when new - might take this on at some point but I'm scared thinking about trying. It's much stiffer than the trail version which I was rolling in high speed turns without insert)
Everything else stock

I think the fork made the most difference with more travel and stiffer than the Pike 140mm it replaced. The inserts were a good upgrade before upping the travel just made it feel a bit damper. I run front and rear suspension slightly on the firm side with a couple of tokens in the front and fairly high psi in my tyres (F 26psi R 28-30psi) so I'm only really using full travel on big hits / trails. Can definitely get away with more less than ideal line choices but I feel more confident and less pinged around on the rougher stuff. But it's still poppy, responsive and snappy but definitely heavier and draggier. Only mega noticeable on tarmac and the ups if I've not been out for a while.

I was in between Medium and Large frame size and I went with the Medium as I'm more into popping of everything rather than racing Strava.

Brakes I still feel could be better and they seem to destroy brake pads so might up the rotor size.

I did most of this before going to the Alps for 4 weeks and taken to Bike park Wales. Thought I might change it back after the Alps but I recon I will continue to run it like this as I prefer to set and forget and the positives outweigh the negatives. I definitely ride up to go down. When I brought the bike I thought the AM would be too much bike for my locals but I'm loving the hybrid TR / AM I've ended up with.

I loved it before upgrading and still love it

I run my 2019 Meta TR with a -2 Deg Headset and 160mm fork, you can definitely feel a difference from the change in the head angle in terms of wheel flop when climbing, but something that takes only about 1 ride to get used to. I did not feel much of a difference in the shorter reach.

I also have a 210x55 shock instead of the original 210x50, I can't say I felt much of a difference there, so, better? I don't know, but, not worse.

A little late but for future reference:
You can turn a 2019 Meta 4.2 TR into an AM without a problem.
Upgraded mine with a 170 ZEB an a 230x60 Super deluxe = 160 rear travel.
Did not notice (clearance) issues riding.

I also have a 2019 Meta TR 27.5 Origin and have upgraded almost everything on it. It has a 160mm Pike RCT3 and a 210x55 Super Deluxe RCT. I am 6’1” and weigh 155 lbs. and riding a size large. Fork is set to 65 psi with three volume spacers. Shock has a gnar dog spacer and a standard volume spacer and is set to 165 psi. For the people who like sag numbers, 20% front and 30% rear. Still utilize all my travel even on mellow trails but no harsh bottom outs. Love the extra slack the 160mm fork gives. It definitely makes riding steeper stuff more enjoyable compared to stock. Super fun and playful trail bike. I would like to get a little more progression out of the linkage so I could switch over to a coil shock. But if you are considering over stroking and putting a 160mm fork on, definitely do so. It transforms the bike, still climbs well and makes the descents even more fun.
