Renthal Apex 35 - 50mm length

Rating: Featured Member Review
The Good:

Nice clamping Looks nice Decent weight

The Bad:

Price is a bit much at full retail

Overall Review:

I love the classic look of the Renthal bar and stem combo. The stem is light and stiff, no creaks, cracks or corrosion in 6 months of use on my long travel bike. The stem will spin on the fork in a heavy crash, but I've only done that once and everything looked fine after and hasn't moved since. The price is a touch high, but I expect the stem to last as long as the bike, not a lot of mtb parts like that anymore.

The Good:

Looks great Lightweight Handlebar clamp really well designed Well made, good bolts

The Bad:

Steerer clamps too thin Not cheap

Overall Review:

Usually I wouldn't have much to say about a stem as they usually should just work and you don't notice them.

The Renthall Apex stem definitely gets noticed because it looks great, it has been well designed (mostly) and really well made. The bolts are quality too.

The handlebar clamps with the wrap around feature are great. It makes the handlebar easy to fit and torque correctly.

The steerer clamp is probably the weak point of the design. I think in the pursuit of lightness they took too much material out of the bands which sacrifices grip strength. I've seen a lot of people over tighten these probably due to this fact. I run mine a little over the torque setting to keep ensure the grip strength is there. I have had it shift on me but thankfully going uphill on a switchback. Apart from that

It's a stem

The Good:

It's a stem, it works.

The Bad:

Could be cheaper

Overall Review:


Not much to say. I does what it's supposed to do.

One of the best looking stems

Rating:
The Good:

The looks! Easy to mount, tough and elegant.

The Bad:

Nothing, nada,

Overall Review:

It's one of the best stems, also best looking IMHO. Paired with a Renthal FatBar Carbon it's a perfect match. Had it for three years now on my Nomad, still kickin' and no signs of fatique. Recommended!

does the job, but clamp desgn issue in case crash

Rating:
The Good:

It does match with my nomad 4 tan color as well as my renthal handlebar. I had it on my both bike with this combo setup. I keep check the torque every 2-3 rides and work flawlessly by far.

The Bad:

As mentioned the gap design on the top clamp make terrible scar if you happened hit on it, I have one of my friend had deep scratch because his knee happened to hit this top clamp gap. I hope new design eliminate this gap to reducing the risk during crash.

Overall Review:

Love it 10/10 IMO, does the job. Hopefully new design getting better. Thanks.

it sure is pretty

The Good:

lightweight and gorgeous

The Bad:

a tad weak for my liking not to mention its pricey

Overall Review:

I bought this stem along with the carbon fatbar. what a pretty setup. i unfortunately was in the process of figuring out my front end and was taking the stem on and off quite regularly. i think due to that i weakened the steering clamp side and both clamps ended up breaking off. this all happened while on a ride. thank god i was climbing and not descending. to put some people at ease, i have to say that if you've got you're bike well set and you don't mess with things as much as i do, you will likely love this stem and have no issues. id say its probably more of a trail stem but i see richie rude running one in the ews which shuts down any further opinions i may have on strength. thats why i feel the failure i had was due to excessive loosening and tightening.

Renthal Apex 3.5 for a 35

Rating:
The Good:

Minimalist design, light weight, just works, and looks good too.

The Bad:

They're a little pricey.

Overall Review:

Another great stem from Renthal. I have two of the 35mm diameter versions. No issues with either. I like the minimalist kind of moto style design. I only wish they were a little less expensive.

A good lightweight stem, but...

Rating:
The Good:

Light weight, I like the split ~220deg clamp design, looks great when paired up to a Renthal gold ano bar

The Bad:

I've broken two, and question what type of riding the stem is marketed towards

Overall Review:

A great lightweight stem that would be solid for 95% of riders, but I personally feel it's a stem for a trail bike and not up to the task of being ridden hard
I've only used the 40mm length x 31.6mm bar clamp so this problem may be specific to that variant, but I've managed to break two in 14 months doing what would colloquially described as "enduro" riding on very rough rocky terrain (New England and NC). Wasn't a catastrophic failure, but a stress crack developed on the top edge of the central bore, visible if you remove the bars. Or, if it gets big enough and propagates out, you can see it with the bar installed. First was covered under warranty, second happened just outside the warranty period, now it's a paperweight. I'm 185lbs geared up and ride relatively smoothly too
