    How To Install Monarch 4.2 on Atlas Sport?

    Hello to my Ibex family. I got hold of a Brand New Rock Shox Monarch 4.2 for my Atlas Sport for $125 and I would like to replace my Manitou Metel coil shocks with it. According to James from Ibex : The rear shock on the Atlas is a 7.5"X2.0 which is the size I have.

    My dilemma is I don't know what parts I will need to properly mount that new shock to my Atlas frame. What size spacers? What special tools? I was not able to find any instructions on how to mount it to the frame. I am holding off on installing it until I have an idea what to do.

    So if anyone here is knowledgeable on this I would greatly appreciate any help.


    So for my suspension upgrades, my red Atlas frame will be sporting a Rock Shox Monarch 4.2 rear air shock and an 09 Revelation 426 Air U-Turn 110-140mm courtesy of my brother. I decided to stick with the Red and Black motiff. A lot of people I run into likes the color.

    Pics will be posted after the install is completed.

    Thank you.
    Raymond

    its a simple process, you need to measure the size of the shock eyelet(the hole the bushing fits into), the screw that goes through the bushing and the width of the bushing needs to be. once you have these dimensions you will need to order them or go to your local shop with the shock model and the width and screw size and have them order it for you. although i,m not sure if the screw diameter really matters but id know it to be safe.
    removal and installation is simple undo the 2 screws that go through the bushings and eyelet and the shock is now free.
    RAH!

    Not a dumb question at all. Pretty much what flf said measure the bolt center diameter this will get you the ID, Then you will need to measure between the shock mounts on the frame and seat stay to the shock eye, this will give you the width of bushings needed.

    The bushings you have may fit the new shock have you checked it out yet?

    Reducer widths help for Atlas

    I measured mine, and clearly wasn't an exact science (I used a ruler, then converted inches to mm). I got for measurements:

    8 mm bolt (didn't check length, will reuse)
    22 mm
    50 mm

    Could anyone please verify? Thanks!

    Thank you guys for your responses. Unfortunately I have to order the stuff online because my LBS don't stock it and I have had negative experiences with them so I don't plan to go back there. When I asked them to tune my bike. After a tune up, I took my bike on a local trail to try her out and the gear shifting was not smooth and my front derailer became loose that it hit my rear tires. Basically, I ended up adjusting my rear and front derailers myself with the help from videos and tech articles online. Now she is shifting smoothly. I look at it as a learning experience and a way to bond with my bike.

    Unfortunately I did not find much on how to install rear shocks hence the reason for my post. Like learning how to mountain bike, I am learning to fix and tune up my bike on my own. It is more complicated than working on my BMX bike in my way younger days.

    Thank you guys for the replies. I got her on using the same spacers. I just had to remove the bushings and spacers from the old coil shock and my brother showed me how to do that. After that it was smooth sailing. Now I just need to get the shock dialed in. Thank you all again for your help. You guys ROCK!
