Switch from 2:1 to 1:1 instantly with a simple bolt-on setup — no cutting or tools needed. Use 2:1 for smoother, lighter reps, or 1:1 for direct, strength-focused resistance. One system that adapts to your goals for more control, more options, and more efficient training.
Made from 3mm steel and equipped with sealed-bearing pulleys, this kit delivers a premium, commercial-grade cable feel with ultra-smooth pulls, no grinding or sticking, whisper-quiet operation, and a highly durable frame that resists bending and long-term wear, ensuring every rep feels controlled, stable, and consistent—just like a professional cable system should.
The slim frame structure saves space while dramatically expanding what your M1 PRO can do, bolting directly onto your current cable system to add dual-ratio versatility, unlock more training styles and resistance patterns, and provide a budget-friendly upgrade without replacing your existing setup—small attachment, huge payoff, massive versatility.Note: Due to the structural design of this DIY Dual Ratio Kit, attachments installed directly below it may experience slight interference.

I installed it and used it 2 times and it was a major upgrade to my routine. Unfortunately today I was doing pull downs with 50lbs and it tore my cable. I am hoping to receive a replacement cable because the machine was working perfectly before this ratio attachment. Also the cable comes out at the bottom it needs an extra cable stop.
Very nice upgrade. Change between 1:1 and 2:1 ratio quickly, especially helpful for back exercise like lat pulldown and row. Did mod to put pulley on the side so it won't interface with the leg holder attachment.
Not sure what im doing wrong. The second it goes under tension it falls off and thats with me pulling slowly at first. Both pulleys and adjusted the part around the weights. Can't do cable flies with 1:1 it max's out at the top before completing the fly. Just went to use it at lower position and pinched the clear coat off the cable as it got wedged between the pulley and 2x2 frame. Any advise would be helpful to prevent further damage to cable or me pulling off the 1:1 ration pulley.
Not perfect Solves the problem of the weight capacity cap and the annoyance of moving hundreds of pounds onto the cable, however it is not perfect. You cannot use the bottom most cable level with this attachment, the bottom pulley will come off of the track. Also, it is very hard to latch the two pulleys together when weights are on the cable, and that is why I am using a third carabiner as seen in the video. For very strong lifters it is worth it, otherwise I would keep the standard cable system.
The angle the 1:1 attachment forces the cable and pulley into will come off and ruin your cable. I got this for free and still wish I hadn’t. It’s a poor design. The rack itself is incredible for the price but the attachment needs an additional pulley to accommodate the cable coming from the side
Definitely recommend!!! It’s a must have for sure in a home gym
The Ritfit Ratio kit was an easy install. Conversion is much easier and will save on purchasing additional weight plates.
I like having the 1:1 option but I did drop a star just from a little frustration with the pulley arrangement when the trolleys are at the lower points.
The lower pulley easily pops out the cable so can’t use the when at lower , other than that it works great as a true 1:1 ratio
The 1:1 DIY Works great, the only reason I gave it 4 stars is the incompatibility with the lat pulldown makes it a bit tougher to use. Overall a great product and I don't regret the purchase
Great
Great, packaging was great, perfect addition. Will be doing mods
First, this upgrade is massive. I immediately felt a difference in my workout with the 1 to 1 system, and I didn't have to load as many plates! 10/10 for that reason alone. I love it. I gave this 4 stars for 2 reasons: #1 - I had to add 3rd-party cable stops. Before installing them, the bottom cable had a great tendency of falling out of the track. With the cable stops, it works great. #2 - Unfortunately, when the cable is at the lowest setting, the bottom cable comes out of the track every time unless you use it at an inward angle. I have simply detached the bottom carabiner and gone back to 2 to 1 when I need to do exercises on the lowest setting. Works like a charm. These little inconveniences are worth it, in my opinion. I 100% recommend this upgrade. 💪🏾👊🏾
Easy install
I really was excited about this. And while it is good, it isn't great, so 4 stars. What is wrong? The assembly was fairly easy. 30 minutes? However the lower cable is only held in place by the clip. And it moves when not under load. So the cable can jump off the pulley. Adjusting would help, but the cable is no securely held. A cable stop is needed. 3rd party ones are available. When at the top of the rack the slack and lack of cable stop makes it not high enough for full range of motion lat pulldowns. Note. The cable stop, when installed could fix this. When at the bottom of the rack the cable angle is too sharp. So you have to move it up one to do seated rows. I LOVE the 1:1 ratio. No longer have to load 200 lbs to lift 100 lbs of weight. Exactly what I want. Note to RitFit. Look at changing the sliding bracket so that the pulley is on the outside of the rack instead of the middle. This would help solve the cable angle issue. Not sure if that will create other issues.
The diy dual ratio kit is a must have. I no longer have to load my stack horns with plates just to work my back. I went with the modified version and it has worked great for me. Great price to double your weight.
It’s not smooth enough when I install the LDM1 Lat Pulldown Attachment, I take it off from my machine!!
Great so far perfect for those heavy lifts! Assembly was super easy and straight forward
Need to make an instruction video as the directions are terrible
Great improvement to use less plates on the pulley system
With the addition of the RTM1 the cable doesn’t have enough slack for the weight stack to sit flush. I have to push down the weight stack for the pin to be able to move in and out of the stack freely. If anyone has any suggestions on how to solve this I’d really appreciate it and with the tightness it’s hard to clip any handles on both top and bottom pulley to get that 1:1 feeling.
The cable drags on the bottom pulley and the cable jumps off completely if you lower it to bottom hole. I would like to return. I went back to original set up.
The cable is short when I used the diy kit. You need to send me longer cables to make the purchase usable.
Adds just enough resistance to make a huge difference in the workout
I’m not a heavy lifter but I prefer this so much more. It’s worth every penny.
This really was easy to install. The kit will save me from purchasing additional weight plates. Definitely recommended.
Awesome addition to my home gym.
Works as advertised and great!
I purchased the Ritfit M1. Added the weight stack and high lat attachment. Excellent equipment and I give it all 5 stars. Recently added the dual ratio kit 1:1 and was very disappointed. The attachment does not allow the cables to be used on the lowest setting. The cable angle is too extreme and will pop off the pulley. I use the lowest setting frequently and bought the 1:1 ratio kit so I would not have to add plates at this position. It was a fail. I have removed the kit and went back to the old setup. Overall, Ritfit is still awesome.
I love this added feature and the assembly conversion was easy.
Rit Fit has been extremely great to deal with on all my purchases! They have been very timely in their responses to my questions, helpful and professional. I would recommend doing business with Rit Fit!
While I have not installed it yet, everything is packaged very well and look to be same quality as the M1 pro. I will be using some of the tricks others have posted online and I am sure if I ahave any issues customer service will take care of it quickly.
Finally came, but install required a few modifications. It didn’t come with spherical balls for cable, but I had contacted customer service and they sent them out. Honestly if the weights I had ordered arrived prior to this order, I would not have purchased this due to the weights provide enough weight, with maybe adding a plate or 2. Setup and usability is not so practical, and I understand this is still 1st gen.
Easy to install and use. I wish I would have ordered it sooner, being able to have both sides go 1:1 or 2:1 let's me link them together for heavy resistance or heavy on one side for me and light on the other for my wife.
A must have this should just be standard but well worth it. I love it
Easy install! Missing the rubber ball stoppers, but support already confirmed they will be sending them over. Used this in a workout today and it makes it so much easier to swap from 2:1 and 1:1, therefore increasing my efficiency in each exercise and saving me a bunch of time. My workout that usually takes me 1-1.5 hours was complete in about 50 minutes. This is HUGE considering I typically work out when my kid is nap if or during lunch.
Love this upgrade! The only issue i have is that it didn’t come with the rubber ball stoppers. This makes the bottom cable clip retract into the pulley mechanism. Overall a good buy though
Love the kit just wish it came with extra stoppers. Customer service great to work with!
The 1:1 ratio works awesome with having the weight stacks. Great upgrade!
