Aligning a Wonky Wilier with the help of a Hambini BB

[@Hambini]

Wow. Very thorough but how much was that frame. You shouldn't have to do that much faffing. It should be round from the factory!

[@Mapdec]

Well yes. But if all frames were perfect there would be little need for 5 year old engineers 😂

It amazes me a 5 year old has a successful business model because high end bicycle manufacturers can't make a round hole inbetween two tolerance limits. Which by the way are common bearing mount standards across many industries.

[@Hambini]

@@waynosfotos I think it's more the colourful 5 year old language, rampant disregard for authority, anti wokeness and general rebeliousness. The holes unless they are hairdresser ones have nothing to do with it. Unless it's Liz Hurley, she's my favourite.

With the precision of modern machinery its amazing how badly they can screw up a simple bike frame.

[@madyogi6164]

Totally agree! How hard can it be to machine/drill a hole through 70-90 mm of material, that (to make it easier) is empty inside? Or when building the carbon frame - like they could not wrap fiberglass material and later on the carbon fibers around some up to spec tube, that would be removed from the frame at the final stage of production (just like a worn bottom bracket, in the future).

[@victorrodriguez2806]

Great work!! Great explanations!! Now my comments ( always negative). I have two frames that serve the same purpose for me. A Bianchi Infinito CV, and a Wilier NDR. Though the Wilier was priced higher than the Bianchi. When doing maintenance and cutting stems I was able to look inside both frames at the headset and the bottom brackets. In my opinion it was night and day. The Bianchi was well finished and clean. While the Wilier was crappy and unfinished inside. While I've had zero problems with either bike. I don't think I would buy a carbon Wilier frame ever again. Both frames are said to be designed for the Paris Roubiux race and built for comfort. They are both very smooth riding frames. They both sprint exceptionally well. They are built with Campy Record groupos and both have Campagnolo's aluminum with ceramic bearing wheels Shamel ultra. I wasn't suprised to see the Wilier frame featured in this video. In fact I'm surprised we haven't seen a larger number featured in your videos. ( yep! That's how bad I thought my frame looked on the inside.) Again , great video.!!

Top job, fascinating process but as others have said it beggars belief that Willier can’t make a round hole and that the frame passed their quality control.

[@jackiegammon2065]

I have to admit that I love this, but I also wonder why newly purchased frames wouldn't simply be sent back to the manufacturer? I realize that shops will see issues like this from bikes that are not brand new and would either need to make a choice to fix it or have the customer/shop send it back in. I also wonder about the folks that own and ride these bikes for many years where Locktite is used that is a more permanent fix, and what happens if they simply need another BB... how easy will it be to remove the BB? Thanks for sharing!!

[@Mapdec]

With internet sales, warranty becomes really hard. You would have to box up the the bike, send it away, and wait and wait and wait, as it goes from dealer to brand and back again. Facing and finishing work often gets debated. Does is affect function? Is it for the factory to do, or the dealer to correct etc. It can take an entire summer to wrestle out sometimes.

[@Mapdec]

Oh. Removing loctite is easy if the figment was correct for the gap. Just heat a little.

[@jackiegammon2065]

[@trwilliams22]

[@jonathanhowson6420]

Just don't buy frames with creakyfit bbs. Specialized and Santa Cruz as well as a lot of other brands use threaded bbs and it just works. Buy a Chris King BB and you have a perfect system with a lifetime warranty on the bearings. Even my Nukeproof threaded bb is brilliant. I have never had a bike in the shop due to issues with a threaded bb, mostly because on say a shimano bb when the bearings are worn its super easy to replace the bb with relatively basic tools.

[@Mapdec]

It’s more like every bike shop has facing and tapping tools to sort threaded bb. Very few have invested in tools and knowledge to work with pressfit.

[@mattttt3057]

Your face gives away the ‘hope this works’ at the end. Nice spin…nearly like a square taper BB? I find it interesting how many times you re-torqued the bolts on the shimano crank. I have Campy cranks on all my bicycles, so this is new to me. Glad I own a TIME frame.

[@Mapdec]

Sure. It’s a tricky process. Depends on the Square Taper BB. They are essentially the same thing on a smaller scale. The dura ace ones on track bikes are amazing. Many are far from amazing. Doing up pinch bolts require this method of back and forth. Stem bolts are the same

[@_Zane__]

I'd like to know how much the total labour's and parts cost was for these repairs

[@Mapdec]

The Hambini BB is on his site. We charged 1 hour. To try and get the Kogal to work would have been a much longer and stressful job.

[@_Zane__]

@Mapdec Cycle Works ah that's not bad at all

[@ariffau]

… Willy Wonka ❌ Wonky Willier ✅

[@jeffdickinson9819]

So, given how much thinking time and how much engineering time you gave to this project how do you cost it? Does the customer get an estimate or a fixed price up front or does the customer give you a budget?

[@Mapdec]

It’s a good question. To attempt to fix the frame to accept the Kogal was going to be a difficult, risky and time consuming job with lots of labour time. To hone out the frame like this and slide in a Hambini is a quick job. We charged an hour for the job. With the measuring tools to hand we can make that decision fairly quickly.

Love your channel mate, quality work. My next bikes going to be expensive after I send it to you from Australia to assemble. Are there any brads you’d say are generally better quality than others?

[@Mapdec]

That’s very kind. There are some brands that reliably produce high quality. LOOK, Pivot, Yeti, Argon 18. I keep hearing good things about Time, but I haven’t seen one in years to comment.

[@feedbackzaloop]

I see a recurring theme of people slaping expensive performance products to fix poor quality, ending up with more expenses. The thing is very simple: when a pair of something bespoke and something standart does not work, it is 99,99% not the standart part's fault. And when two do not have same quality, you gotta make them meet it, not maximise the sum. So, gotta re-bore the frame and it will fit Kogel, or downgrade to the cheapest sloppiest BB with nylon cups. Hampini BB with Locktite is great too, but suboptimal.

[@Mapdec]

Reboring the frame is way outside our tooling capabilities. And anyone else I know. It would require a mill, some sophisticated alignment tools and jig. There is also a raised section in this frame where the cable guides locate that would stop a 40.98mm bore going straight through. It would need to be flipped in a jig. Ball ache!!!!

[@feedbackzaloop]

@@Mapdec a 5-axis cnc at least, yeah. Actually, no. You got quite close to the desired result. So, it takes an imperial ton of measurements and sanding. Mills, jigs, etc are only measures of mechanization. Good for repeatability and further automatization, absolutely not necessary for one-off jobs. But, extremes aside, reamer with a through hole, pair of V blocks, shims and a bit of tippy-tap-tapping is sufficient with not much effort involved.

[@2906rick]

What did you use to make the hole bigger. My bottom bracket hole is 40.94. I got a hambini bottom bracket bb86 and wanted to make the hole to 40.98.

Oh. I’m sorry. From memory it is a Sealy Honing tool 280 grit I think that covers the 41mm size. The caad 10 is aluminium. You should use the park tool 41.94mm reamer

[@Machoman510]

@@Mapdec Much appreciated. Are you aware of any other honing tools for aluminum frames that may be cheaper? I wonder if the Flex-Hone tool would work using a 1-3/4 inch tool for just a bit to hit the ideal 41.98mm. I'm installing an Hambini BB.

[@chucktalks63]

I know this is a special case, but I just want to advocate for not using loctite or retaining compound on other pressfit installations. We have had multiple hambini BBs come in with people wanting them changed, and the previous mechanic loctited them in. It took absolutely ages to get out, and is a worry about damaging the frame. Other people have used loctite on their SM-BB71/86 and it has required dremeling to get them out. Normal aqua proof grease suffices for 99% of installations. We have also experienced with loctited BBs they are more likely to creak.

[@Mapdec]

You have to check the size of the hole and make the right call. Hambini specifically specifies retaining compound in a correct size hole. Mechanics do as engineers design. Problem are when mechanics don’t measure and make assumptions. Also. Removing them, use a shock freeze on the aluminium once the bearing is removed.

[@janeblogs324]

Grease won't take up the torque load. There are portions of air gaps all around the BB cups which is the opposite of a press fit. Grease is hiding the creak but the BB is still moving and wallowing out the frame. The only solution is oversize the BB holes, epoxy the gap bonding to the frame, cure for 2+ weeks for full contraction, then ream the epoxy to spec. A very easy job with the reamer currently being the only rare/expensive component.

I'm not a fan of the wheels/hambiñi solution still. You've got a hotdog down a hall way problem, their solution is to just slam the doors shut on the tips of the hotdog. But all the pedaling load goes through the walls of the hallway. So far no ones recorded the detriment that these BBS will cause to the frames over time. We really need a BB cup that has 3 or 4 jaws that expand outwards to create a friction fit on the walls of the BB, instead of clamping the edges of the frame
