Renthal Apex 35 stem 5 months review

Pros:

  • So far I haven’t had a Stem that held on to the handlebar as well as the Apex35 stem, I went for many months from the middle of the winter to the spring without ever needing to do anything. It outperformed the Race Face Atlas Stem.
    It might be the smart clamp design, maybe the materials used helped too, The stem is made of 2014 & 7075 alloy.
  • The stem held the bars well, there were no issues with losing bolts or any other issues.
  • The rental stems have great design, which allows low weight, But I did not notice any difference in stiffness & ride feels, from the Race Face Atlas Stem, which is heavily overbuilt.
  • The stem is well machined, very smooth, no rough surfaces, but the edges are not rounded off to the section between steerer and handlebar are quite pointy, but this does not matter much, unless you slam your hand there, which is unlikely.

 

Cons:

  • The bolts showed signs of wear after the first installation, the tolerances between the tool and the bolts are quite loose, the diameter measurements are between 4.15 up to 4.24mm The park tools measurements are 3.99mm, the after few times of tightening the headset, I managed to damage the bolts, the bots became more damaged after tightening headset.

It might be that the bolts I got are just a manufacturing fluke for this batch, but there is no way for me to know for sure, but if all bolts are like this, this is a huge disappointment and should be addressed ASAP.

 

 

Verdict:

This stem seems like a great option if you want lightweight, durable, stiffness, This is one of the lightest stems the market now, and it’s robust, so it’s a no-brainer, Apex35 Will go on my next bike.
