Hi Guys,

I have an argon 18 e118 time trial bike and I need to replace my headset bearings. It says that they are MR1122 (1 1/8”) and MR136 (1 1/4”) but I was able to find different types of those bearings, such as 41.0 x 30.15 x 6.5 mm. Any idea of which ones I need?

Thanks

    you pull the bearings and measure with a vernier. thats what mechanics do.

    The numbers you need are marked on the circumference of the bearing.

    measure the bearings the relevant points are outside diameter inside diameter and depth. check if the sides are straight or not, go to any of the bearingfactors on the internet. put the measurements into the search function. choose one of the bearings. usually theres lots of different options. theyre all the same thing, its in a bike not an industrial machine or scientific experiment. chose a brand youve heard of, make sure theyre sealed.
