First Look: 5DEV's Titanium Chainring Promises 3x the Durability

Jan 24, 2023

5DEV, the manufacturer of those wild-looking aluminum see-through cranks, has just released a titanium chainring designed to be used on both mountain bikes and e-bikes. The rings are available in 34 and 36-tooth sizes and use a 104mm, 4-bolt BCD mounting pattern – there's no direct-mount version at this point but it's in the works. They're claimed to weigh 48 grams.

You can get your 5DEV chainring in bronze, purple, teal, or raw, the latter being the only correct choice for anything made of titanium. All options cost $149.99 USD, and they're said to last three times as long as an aluminum chainring.

Why might someone want a titanium chainring? 5DEV says that their ring will last three times as long as a much softer, faster-wearing aluminum version. Chainrings typically wear out slower than a single cassette cog (or entire cassette) and need to be replaced less frequently, which is why most bikes come with aluminum chainrings that weigh less than a steel version that would, of course, last longer. But a titanium ring aims to combine the low weight of aluminum with the durability of steel... for a price.

Just like their stem and cranks, the chainrings are manufactured in San Diego, California, and are not inexpensive, with all four color options costing $149.99 USD. That's in the same ballpark as an XTR direct-mount ring and a bit more than one from SRAM but, given that 5DEV says that they, "provide at least three times the durability and longevity of your aluminum ring," would you consider one?

Is a titanium chainring a smart upgrade or a beautiful extravagance?

 A quarter? My RaceFace steel ring was $15 on sale. $20 at full price. They are 100g heavier though, if that matters.

 Quarter? Sram steel chainrings are $15. Try 1/10th.

 @mtblol: ok and a $2500 bike can do the same thing as a $10000 bike, certainly doesn’t stop people from buying the latter.

 My M8000 series XT ring is around $60usd. It has an aluminum body with steel teeth. Not sure of the weight, but I remember it being substantially heavier than the Wolftooth it replaced. The Wolftooth lasted almost two seasons before the narrow teeth were like little daggers. I finished my third season on the Shimano and it's teeth are still in very good condition. For the Ti ring to be a better value than the Shimano it'll have to last nearly a decade...

(grammar edit)

 I got tired of my chain rings wearing out pretty quickly and looking like shark tooth daggers, so I too went and got a Race Face steel ring.

It still looks new and perhaps its related, but the chain I've run with it seems to have also lasted much longer.

Only downside is that the ring is significantly heavier, when you compare holding one in each hand. But that extra weight sure beats blowing through a $60-80 chain ring once a year.
  • 14 13
 Only if it's cheap steel. The Wolftooth steel chainring is $120 but it's a way better investment than a titanium one if you aren't a weight weenie.

"104 BCD stainless steel chainrings can last 5x longer than aluminum chainrings. Wolf Tooth has chosen to use 416 stainless steel despite the added expense and machining difficulty. The 300 series steel, often used by other manufacturers, is tough but still softer than the 416."

 Steel always bends well before it wears out. I’ve never had much success with them. Aluminium rings don’t bend and don’t seem to wear out anyway these chainrings are for people who’ve bought like E wings or something like that and they want to carry them over from bike to bike. They cost more than an entire XT crankset and bottom bracket.

 Agreed. I paid $12 for my last steel chainring.

And, while it weighs more, the longevity is... impressive. And while I do care some about weight, I also care about the cost of consumables.

That said, I can see the market for a Ti ring. If it is truly 3x the durability of AL, then the pricing here seems to make sense. They don't look too great compared to steel in terms of dollars per lifetime, but I don't think they were ever supposed to.

Although I'd have thought the market for TI chainrings was more in the 30-34t range, not 34-36t. But maybe their chasing XC pros, and Ebikers?

 Actually no, steel doesn't do the same thing, it does better.

Aluminum is the lightest of the 3, also the weakest. But if your constrained by size can be used for a favorable strength to weight ratio. It's also VERY easy to machine, cut, sand, shape, and weld. Tubes can be butted, shaped, bent, etc, thus it's popular with early dual suspensions with a zillion different designs for the rear suspension.

Titanium is stronger, but much harder to machine, harder on tools, hard to weld (can't expose to o2), and hard to shape. It's memory makes even something simple like bending a tube hard, since it will return to it's original shape ... until you go too far, and might not return to where you want it.

Steel is stronger still, easy to weld and machine, but not as easy as aluminimum. Doesn't foul tools, and doesn't require a nitrogen bath to weld. It's by far the strongest of the 3 if you are size constrained.

So for things that can be any size/shape, aluminum is often the best, so it's cheap/easy. It's particularly friendly to CNC machines or tig welding. Ti is stronger, but MUCH harder to machine or weld. Best for relatively simple things, which is why Ti frames are much close to simple triangles than aluminum frames. However for maximum strength and maximum life for any fixed size, like a chain ring, steel will be more durable, stronger, stiffer, and cheaper.

 @Mac1987: it's true 100 grams doesn't matter but this is only 1 piece of the puzzle. what if you save 100+ grams in 10 different ways through component selection: pedals, fork, cranks, chain ring, wheels, brakes, tires, bars, dropper, chain, cassette, grips. It goes on and on. then it can add up. One can easily shave 1500 grams on components alone which is over 3.3 lbs. is that worth the insane amount of money? No, but it's nice if you can afford it

 @knarrr: Agreed, the bb area is the best location to have your weight so adding a little there shouldn't be that much of an issue. Before I started using oval front rings, I was just using a double crankset (so 22t, 32t and a bashring). Never replaced the granny so I don't know what these cost, but the steel Deore 32t ring was 9 euros to replace. That said, I've got the feeling I've had to replace this steel 32t ring more often than I have to replace my aluminium Superstarcomponents ring (34t oval). From what I understand, the top guide I'm using does reduce wear on the chainring as the chain approaches from more moderate angles. Maybe without a top guide, aluminium chainrings do indeed wear quite fast. As it is now, I'm wearing out (or mainly, developing burrs on the teeth causing the chain to skip) the smaller XT or XTR sprockets of my 10sp cassette than that I'm wearing out the chainring. Steel oval 34t chainrings for 104BCD are rare (can only think of Wolftooth) and it will take forever to see it be worth my investment.
  • 1 0
 @Quinn-39: Never mind. I was absolutely positive I’d ether bent or folded every steel chainring I’ve ever used well before they showed signs of wear and all the aluminium rings I’m currently using haven’t lasted years without bending or wearing out. My mistake.

 @hamncheez: To weight weenie out for a moment...

SRAM DM X-sync 2 34t steel, 141g, $25 MSRP
SRAM BCD104 X-sync 2 34t steel, 136g, $25 MSRP
Wolf Tooth BCD104 steel, 72g for a 30t, oddly 88g for 32t so I'm guessing 95g for a 34t, $120 MSRP

So if you're already planning to buy the Wolf Tooth, maybe an extra $30 isn't so insane for a different weight/durability optimization.

I'm not that customer, but I'm happy with whatever 7075 rings are on sale, and a guide with bash plate.

 @TannerValhouli: that's wrong. I'd destroy a $2500 bike. Probably destroy myself along with it. I've ended up with top of the line bikes because everything else breaks or gets dangerous when you're pushing it, due to shit breaks and suspension.

 I tried the steel chainring and it was noisier. Went back to aluminum. Also tried aluminum derailleur pully wheels and they were noisy as well and did not shift as well because they were not narrow wide. Went back to the SRAM composite pulley wheels which are much quieter and shift more precise.

 @onawalk: The Wolftooth 416 will last about twice as long as a titanium chainring and is less expensive.

Wolftooth lasts 5x longer than aluminum. 5DEV claims 3x as long but I'm a little skeptical of that on a mountain bike where the chain gets dirt in it. Titanium is very strong but blunt.
Not as abrasion resistant and scratches easier than steel.
  • 2 0
 @DoubleCrownAddict: I guess the idea of investment is subjective. Clearly this ring wasn’t developed to replace a steel ring for those that choose to go that route, it was developed to replace alu rings, which are light, stiff, but wear quickly.
This at $150, while expensive as far as I’m concerned is pretty good value if you’re looking to replace a (wear quickly) alu ring, with something that’s just as light.
Just because something doesn’t appeal to you, doesn’t mean it doesn’t appeal to others, and isn’t good value for them…
  • 1 0
 @onawalk: Those who say aluminum chainrings wear quickly, are you using a top guide and what size chainring do you use? Before I went for an oval chainring (hence went with a single front ring), I was using a dual ring (and bashguard) setup with a steel Deore 32t shift ring. They were cheap (9 euros a piece) but I felt they wore much quicker than the (currently 34t oval) aluminum chainrings I'm using now (from Superstarcomponents). Sure if I'd frequently have to replace them I'd be willing to invest in the steel alternative and the slight weight increase doesn't bother me one bit. But these aluminum rings already last pretty much forever so there doesn't seem to be much reason to get a steel one. But that's just me. So yeah, if you are wearing aluminum rings quickly, are you using a top guide?

 @onawalk: No chainring made of any material is designed specifically to replace a chainring of another material. If you used the word marketed instead of designed your sentence would make sense.

$150 for a ti chainring is never a good value unless you simply love ti, which some people do. A steel chainring is only about 15 grams lighter, vast majority of riders are gonna take that if it's twice as durable. There isn't much appeal here for the price unless you simply love ti.

 Pinkbike should do a 'Bling, Buy, or Skip' seasonal feature for these kinds of items they regularly introduce on the front page. I firmly place these in the 'Bling' category. I'm sure the ring is many grams lighter than a steel counterpart, but it lasts the same amount of time, and costs 5x more. Its saving grace is that it's Ti, and Ti is always cool so I can't say 'Skip'.
  • 12 2
 Titanium is also a lot heavier than aluminium though, so unless you can make the ring almost half the volume of an aluminium one, it will still be heavier and therefore skip.

Love the feature idea though, @brianpark.

 You don't typically buy Ti parts because they're the cheapest. They're not even always the lightest. Frequently, Ti parts are bought because the buyer just loves Ti. I love Ti. My wedding ring is Ti. I have Ti spacers under my stem and Ti centerlock rings. I don't have those things because they're the lightest, but because they're Ti. I am absolutely 100% the market for a Ti chainring. When they get them one piece so they direct mount, I'll probably get one to put on my EE Wings...as long as they have the tooth count I want.

 "Not inexpensive" is honed journalismspeak to avoid pitfalls of direct declaration:

"This is expensive" is a direct declaration of an opinion as fact. This absolutely equals "this is not cheap" and will illicit flame responses from the comment section.

"This is not inexpensive" is a more limited declaration, avoiding the "expensive" claim, dulling the same opinion and leaving an option open to reader interpretation as "this might be expensive" and implying "... expensive to some but not to others". And Levy doesn't have to clarify to whom and how much.

 I went back to steel chainring after going through a few alu ones. Only downside is a bit of rust that build up mostly on the off season for me. Best side of it is half the price of an alu chainring. Would not pay that much for a titanium ring but they look nice and they won't rust while lasting a bit more than the alu ones.

 I ran Boone Tech booneti.com/collections/chainrings Ti Chainring and Cassette cogs on a dream build Ti Boulder Bike back in the mid 1990s and loved the durability and especially the amazing sculpted curves of the "Big Ring". This one looks very plain. Too bad. One of the advantages of Ti, is that it's so much stronger that it can be sculpted beautifully, using less material, than steel or aluminum. A point missed on the wallet drainer from 5DEV. Looks like. they hit a home run with the cranks, and dropped the ball with the chainrings.

 Hard sell. If you care about the weight, there are options out there that are 2/3 of this. Alu chainrings aren't exactly 'race day only', but if you are counting grams for a race, you don't care much about longevity. If you care about longevity, five SLX composite/steel combo rings will last many times longer for the same investment and a 53g weight penalty. So the only markets are those for whom this is just the compromise they have been craving, and those who just want bling everywhere.
But hey, that latter category is big enough.
With the relative prices of cassettes and chainrings these days, I'd prefer my chainring to wear at a similar rate to the cassette and not put a new chain/cassette combo on a half-worn ring, accellerating wear.

 Shimano chain won't really work on "normal" NW rings because the inner plates have an extended chamfer that the Shimano-compatible rings account for with a corresponding chamfer on the wide teeth.

You can see a bit of a chamfer on these rings, though it looks about the same size as many existing rings like RaceFace, Wolf Tooth, OneUp, etc, that might not indicate Shimano 12sp compat...

 Yield strength to weight of 6alv4 Vs heat treated 416 is almost identical, and in a non thin wall application, means a properly designed chain ring will weigh the same in either, except the 416 will be cheaper and slightly harder. Another overpriced under-engineered product from the turkey gobblers at 5dev for the over monied fwits who think a warren truss is a great torsion member. Imagine if they used a real tool steel with a nitriding...
  • 1 0
 But wouldn't you use similar tooth profiles in either material? Meaning the Ti will be lighter and wear faster. It would be very interesting to see how long a drivetrain fully out of a hard tool steel would last. I have no clue about production difficulties for those metals, so no idea if it would become much more expensive than current options.

 Chains don't wear because the gears are a harder material or just doesn't wear. It's not a trade-off where one piece has to wear because the other doesn't. Chains wear [internally, pins and bushings and rollers] because they move, and some of the movement is under tension.

 Maybe I wouldn’t buy this, but an Absolute black oval ring is close to $90, and this is just a bit under double that price. Though, Titanium is definitely boutique, and not what I’d personally buy unless I was going for a total bling build. I guess I’m getting closer and closer to that though.

 Harder metal will likely wear chain faster. So you'll be replacing more chains and less rings. Also, they can't use Xsync-2 chainring tooth pattern so if you're on SRAM you will get a louder, lower performing drivetrain with these rings.
  • 1 1
 It doesn't work that way, at least on dirt bikes it doesn't where I could wear out a well maintained, but lightweight drive train completely in about 6 weeks.

The steel sprockets as they don't wear (much), and then begin stretching your chain, result in much longer wear throughout the entire drivetrain.
  • 2 0
 Since the ring won't wear as fast as aluminum one would, it won't affect the chain wear. What affects the chain wear - and causes elongation - is the crap/grit that gets into the rollers and wears the pins. That process is accelerated when the rollers wrapped around the ring are not supported evenly and thus the load is not spread evenly amongst all engaged rollers. But since Ti or steel ring lasts longer, chain wear will depend mostly on its' care/maintenance.
  • 4 1
 If anything the harder chainring will hold it's shape better and engage better with the chain for longer, increasing chain longevity. I don't think I've ever seen a case where hardening the softer part has increased wear on the hard part.

  • 1 0
 @arek: Rollers being evenly supported would be the case of ring and chain are worn by the same amount, right? Or am I missing something? So if you have a really slow wearing chain ring it would accelerate chain wear once the two get out of sync. And then again when you replace only the chain. In my experience using two chains and frequently changing them makes everything wear at approximately the same rate and I replace the whole set once it starts to seriously show shifting problems.
  • 1 0
 @ak-77: I think real life scenarios can vary wildly, depending on different setups, riding conditions, maintenance/cleaning regimens etc. My point was, that the harder wearing ring material (vs. typical alu) is not going to be your main concern when it comes to chain wear.

 A) Chains don't wear much where they touch the gears. The wear that causes "stretch" is mostly on the pins and [integrated] bushings.

B) A chain-ring that doesn't wear as fast, that maintains its shape for maximum and proper chain contact, will help a chain last longer by spreading the forces through many links at a time.

C) You're probably on a worn ring and worn chain right. A new chain OR ring would probably be loud for a bit as the worn part accelerates wear on the new part.

 I thing longevity is really fucntion of how much work you push through the chain. Chainrings arte ususlaly messed up mostly by stretched chains. In reality chain is way bigger problem I for example am am replacing the chain every 2-3 mounts average, which 5-6 chains per year. This is for XX1 chain. ~$90 after the 10% discount + the Cali tax at sports basement. It last between 500-800 miles depending on how much I climb. So in reality can be a month of biking. I see people are getting 2000 miles out of chain but those are probably on a downhill bike!
