Renthal Apex35_1029edit

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.

Renthal Apex 35 stem
  • 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.

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).

Short term review: Rock Shox Recon Gold TK Solo Air OneLoc 26″ Fork 100mm Straight 9QR

uncut weight

 

Bad experiences:

First time I received the forks one of them was soaked in oil & grease and the seals were had popped of under transport.

one of the forks had seals that were way too easy to remove and press, I could press them back in and remove them with my fingers, clearly not up to specifications.

The fork was Also leaking air, and had horrible knocking sound coming from the rebound side.

But I returned the forks and they got rebuilt by Rock Shox, after that they performed how they should, no seal issues.

 

This fork was just a fast & easy solution, I just need to have a bike to ride, so I had to buy a fork, I did not know about any service centres that serviced Marzocchi forks, Which I had at the time.

 

Pros:

  • Not crazy heavy, the alloy steerer & magnesium lowers results in a decent weight.

Cons:

  • the lockout is reversed so it’s not unlocked by default as on previous forks, which is stupid., combined with the Rockshox OneLoc remote it’s even crazier, the fork would unlock due to vibrations & due to the flimsy remote.

The Poploc was is much more reliable, the same goes for the Marzocchi & SR Suntour remotes, but none of them has a hinged clamp.

  • The bad tyre Clearance:

You can’t use a mudguard with 2.3 tyres, 2.4 tyres will rub.

2.1 Suomi Studded tyres & Mudhugger FR mudguard, got enough clearance.
