I would drill it. A lot of the material is there and physically does nothing. They've just left it because it costs time and hence money to remove it. The metal is 4-5mm thick and I'd be surprised if drilling two 5mm holes made a massive difference - just don't go to the corners. Also preheat the metal in the oven to 60C before you do it, it will reduce the risk of a crack from drilling that you can't see. I appreciate a lot of commentators will be risk averse but this is a KZbin channel and people are tuning in to either see you hurt yourself, make an expensive mistake or end up in Accident and Emergency! Best of Luck

[@renegodde5483]

LOL, well said. I‘d say „drill it“, too, but because I like watching your stuff not for the sake of seeing you hurt yourself, I‘d say just make sure you regularly inspect those holes. If no cracks are starting to form, you‘ll be fine. That thing isn‘t just going to brake from one moment to another.

Will straight drilled holes work or should they be drilled at an angle to avoid damage to the cable housing? The latter would make it considerably more difficult, even with some clever use of a Dremel.

In the 70s and 80s, my dad was a major 'recycler". He often went to the local garbage dump and brought things home to tinker with. He brought a car wheel home one time, but the holes for the lugs weren't right for the car He wanted to put it on (my car). So he redrilled it. Do you know what happened? It formed cracks between the newly drilled holes and collapsed while I was driving. No one was hurt, but my father, who had a PhD and a masters too in another discipline, learned a valuable lesson. Luke, don't be like my dad!

I agree. Don't follow Hambini's advice. The Stem is a critical item

[@leonardobonizzato9865]

I got the same cassette, and so far no issues in 4000km, working well even with a di2 Shimano. As for the drilling, I'd be wary of drilling so close to the handlebar clamp, since it's going to be a loaded zone. Rather I'd 3d print a cover which attachs underneath and covers off the cables

[@yjk4833]

Luke, we like you. Please don't drill your stem, especially near the clamping area. That's where all your weight rests on the steerer tube. I do see that stem looks pretty chunky on the inside, but I wouldn't risk my teeth hiding that much of cable.

[@Mr_RichardH]

I have to agree, where you're considering drilling are both essential to the structural integrity of the stem. For the sake of your teeth, don't do it!

[@feedbackzaloop]

The spot Luke's pointing at is far enough from the clamping zones. High end stems even have webbing where normally a tube is. Rather, consider how cleanly the hole is drilled and deburred - that might start cracking.

[@owensnicholas]

It's hard to know if that alloy stem has been heat-treated, but most cast alloy parts need machining while the alloy is still soft and malleable, before final heat-treatment to guarantee the strength and stiffness needed for things like tapped screw threads. Machining something that's been heat-treated can have wildly different effects depending on the type of heat-treatment the alloy has had, so it's a gamble that might go one of several ways, a few of them being undesirable. 🥖🥖Rather than trying to drill the stem, why not 3D-print something that covers up all the mess under the stem, replacing the existing plastic aero wedges where the bar meets the stem clamp? 🥖🥖

[@florian4181]

With such cassette, you always trade the low weight for the fact that it is harder to adjust and significantly louder. This is because it is a single block or semi. Chain noises are directly transmitted through the freewheel of the wheel to the axle and frame. Even SRAM had to realize this and added rubber spacers between the sprockets on the Force cassette. Maybe you can add such at this too?

[@the6ig6adwolf]

The fact you bothered to ask if drilling the stem/bar was a good idea should tell you that it isn't.

[@droneracer]

Those sheared teeth - probably a result of shifting under load. If you're really unlucky, you can bend a steel cog as well (not individual tooth, just a section of the sprocket)

[@TimSwinson86]

Shimano have been using aluminium large gears on their XT and XTR mountain bike cassettes for a while so there's no major issues using aluminium itself apart from less durability long term (it's simply a softer metal than steel), it depends on the quality of the alloy and the machining used.

[@andyamos8594]

If its OK by Hambini, its OK by me 😀! Even consider using a stepped ferrule going in to the stem allowing you to downsize the hole and use a thin inner sleeve tube for the inner routing which might also help installation?

[@siegfriedeckstedt3037]

Careful with the drilling. Suggestion to make the whole oval in result so that the cable doesn’t need to be fitted straight but can go diagonally. And use reinforcement around the wholes. Welding would be ideal. Seems like a bit of a stretch.

[@okim8807]

The "Recon One-Piece Cassettes Al 11s 11-28T" should be lighter than the sprocket introduced here. It weighs 117g. However, since all the teeth of sprockets are aluminum, the lifespan will be short.

[@VINSANITY19]

I just remembered the Neutron Cassette that China Cycling reviewed at the Shanghai Bike Show. Riro had the same material construction as a neutron.

[@iberiksoderblom]

Sure you can drill it, just be carefull with the heat. Angle the drilled holes slightly. If you take a look at pre-drilled stems, you have plenty material.

[@TimBlockinger]

if you do go ahead and drill it to pass the hoses internally, cut off the screw threads that extend into the stem. these will be rubbing against the hoses maybe and cause wear. Feeling around the interior for any sharp edges would be prudent as well.

[@ronaldsmith5375]

I always question tampering with bicycle stems. I've seen way too many stem failures and aluminum is very unforgiving when it fails. As noted by previous comments the ability control/steer a bicycle when the handlebars become detached becomes severely limited. If you do elect to press through on this experiment I advise obtaining additional heath/life insurance.

[@KurtisPape]

In the larger gears there is more chain engagement, which reduces the wear in each tooth, that's why it's pretty common to run aluminium chainrings on road bikes and they last for ever.

[@PaceGalore]

Why not use a one-piece-cockpit with fully integrated cables like the "Rose One-Piece-Cockpit Race" (only space for 2 cables, Rose Endurace Cockpit if you need three) or a cheaper Aliexpress-alternative? That way you could fully hide all cables without drilling the aluminum stem and the cables stay serviceable too. If you wanted to recycle the existing parts, I'd consider drilling just one hole in middle of the stem, thus not affecting the structual integrity and using the hole to fit a cover cap like the one used with the abovementioned Rose Cockpit. That way you could fully hide all the cables down to the head tube too.

[@andrewpatton1950]

I'm always tempted by the ultralight/aluminium cassettes and have run one in the past. They all shift great on the stand, but nothing shifts better than the oem Shimano cassettes. Curious for the long term review and if you have any annoyances with the shifting! Otherwise it will be an easy way to save 100+ grams.

[@TimBlockinger]

drilling into the stem would be easy to do. I think de-burring and rounding the inside surface of the holes would be difficult. I'd be concerned about a sharp edge cutting into the hydraulic line over time. It's in an area where you won't be looking frequently so could go un-noticed until leakage started.

[@Peluche54]

Got this cassette in 11-32, but will return it. Shifting is pretty poor on my bike (90's steel frame, Ultegra R8000 groupset, YBN SLA chain), light years behind a Shimano or even a Campagnolo 11s cassette. Maybe it would be better with a Shimano chain and another derailleur hanger's geometry (mine is a bit on the edge of general specifications), but I suspect cog's ramps to be poorly efficient. Quality-wise it doesn't look very good neither, the spring washer on the lock ring is so thin it crumbled when installing the cassette...and it looks like you can tighten it forever, but I did stop to what looks like an acceptable torque by rule of thumb. Some reviews on forums are talking about alloy cogs being even weaker than standard alloy cogs (and it's still far weaker than steel), with occurences of broken teeth. Will try the Goldix / Ztto ful steel cassette 🙂

Drill that stem. More likely than not, will be fine. Obviously, don't start drilling 20 holes in it. Fwiw, I retired one of these alu and steel k7 after 5-8k km, the alu cogs started skipping. If you live on the flat and don't do hard low torque high power efforts, and wax your chain, I think you can get incredible life out of these k7. I've just installed one of the these full steel monobloc. Paid 70 EUR for it. I'm still adjusting my RD for it as the spacing is a tiny bit different.

[@themusette5894]

Luke and Hambini reinvent drillium. You could try hacksawing halfway through your stem just for laughs. I'd say no to both. I'd prioritize mechanically efficiency of your braking system. If it's cable, forget the sharp curves.

[@doesitgame]

[@BlurdeBlah]

[@Technotranceism]

Modifying the aluminum stem probably won't hurt anything, just be sure to de-bur the holes to eliminate rubbing, or use some inserts (aka guides) with bigger holes. 🥖

[@mikeh6286]

The smallest alloy cogs wear first. Also shifting suffers because they make the alloy cogs a smidge wider to mitigate wear and thus shifting performance suffers. If you've ever had issues shifting between the smallest cogs this will be a problem because you have to index based on the biggest alloy cogs to get adequate performance. That indexing will conflict with an optimal indexing when looking only at the small end. So you have to compromise and not get optimal shifting on either end of the cassette.

[@amonynous9041]

Bought a ztto cassette a few months ago..Superlight and looks bling. But…. After a few rides the 3 long thin screws that hold it together started coming loose and started rubbing on the freehub body, causing the cranks to not be able to spin when not pedaling. Tightened them up but they’re so small you can’t really torque them up properly. Nice for the amateur cyclist but won’t hold up to every day use.

I wouldn't drill the stem or the carbon handlebar.

yup, you'll compromise the strength of the stem if you drill next to the steerer tube. You can test it by putting 4x or 5x the expected weight and see what happens, all my stems could probably handle 300lbs being gently set on to them. use a test base (2x4's upside down fork) and use a old steel steering tube/fork. Engineer the test platform so if you don't have weights, use your body weight and garbage bags filled with water, and only fall an inch, not 36. I'd like to see the test! Actually, I've been thinking, your handle bar will probably fail before that stem. Just stay close to the center, away from the corners or edge.🥐🥐
