Pros:

  • The stem held the bars well, there were no issues with losing bolts or any other issues.

So far I haven’t had a Stem that held on to the handlebar as well as the Apex 35 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. it’s not only the bar that’s held on securely, but also the stem to the steerer-tube, so I have had I haven’t had issue with play in the headset, because the stem holds on so securely, the bolts don’t loosen fast like most stems I have used in the past, for example Race Face Atlas, I have experienced play in the headset & handle bars slipping, due to bolts getting loose, but never with Renthal Apex.

I of course thread locker, I use Loctite 243, which I have used on all of the stems I used.

The only times I made it loosen was without Loctite or not cured with big temperature change.

  • 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. The caliper might have not been very accurate, but I know the tool is not as snug fitting as I think they should be. I later used Teng tools bits, which fit better than Park Tool, but still there is a lot of play.

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 disappointment and should be addressed ASAP, but the Hex key only slipped once, I haven’t had issue since then.

A rider had issue with two stems cracking, he did enduro riding, but I haven’t had this happen yet.

Verdict:

I can recommend this stem, 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, Apex35 Will go on my next bike(s).

8 moths review: Race Face Sixc 35 800mm 20mm handlebars

I won’t go too deep with technical stuff and specs, which have already been mentioned in other reviews, here are my experiences with these bars so far.

The bar dampen vibrations well, the bar feels great, it was a huge improvement from 720 Bontrager race lite bar and stem.

Enough flex but not too flexible:

Some flex can be felt if you get some weight on the bar, for example with some front wheel trails moves, but nothing too crazy, but on the trial when shredding hard, there is no awkward feeling, these handlebars feel great, the defenitly dampend vibrations, but they won’t eliminate vibrations completely, that’s impossible, with narrow studded tyres, rough winter conditions can cause a lot of vibrations which will be felt even with silicone grips, I have not tried wider studded tyres yet, But I am quite sure it would improve degrease vibrations, but for summer riding, these bars have been greatm they dampened vibrations well, combined with silicone grips, they were a good combo, but harder you ride mroe dampenign you woudl want, So that’s why I have ordered Rev grips.

Survived several crashes:

The handlebars survived several crashes, I have jumped off these two skatepark ramps, and landed on the handlebar, no damage was done, I rode hard for several months later and no cracks.

I have also crashed while climbing a bike path, due to my joint slippage issues I accidentally did a brutal turn to the left and lost control of the bike, and the bike slammed hard down on the asphalt, there was no damage to the bars, but I bruised my shoulder.

I have noticed some white spots on the end of the bar, it’s probably just clear coat damage, it only happened on one of the two bars I got.

I have been riding through summer & winter, and the bars performed well, some say to avoid carbon in the cold, I have been riding in at least down to -10C, without any issues so far.

These bars are a great choice if you like colour matching bars for a custom build or improve the look of your current bike, but the white/silver look will fit any bike.
