We discussed how he and his partners built a concept store and restaurant in the former stables of the De Koninck brewery, how they turned a 200 year old building into a modern bike shop.
Velodome was the exclusive Rapha dealer for the entire Belgium, Netherlands and Luxemburg. We look at the new brands they found and promote since Rapha decided to end their presence in retail stores.
Another interesting subject was the enormous rise of e-bikes in Europe, how they took over the majority of bike sales in a shop that was mostly aimed at road and mountain bikes. We look at how the EU supports people with tax benefits to get them out of their cars and onto e-bikes, but at the same time is struggling with regulating these hyper fast bikes on public roads.
Thanks to all partners: Philippe, Stijn and Maarten for their time in producing this video and for bringing better bikes to the people. See the interview on the Kogel Bearings Youtube channel
With the days shortening and Kickr season right around the corner, I thought this is a good time to share some of the best cycling documentaries and tv-shows I have seen recently. Nothing helps kill time like staring at the screen when the indoor trainer is testing your mental stamina.
Being a lover of most things on two wheels, I hope I managed to find a good mix of all cycling disciplines. I have posted links to Youtube where I could find them. Others are available on Netflix.
Here’s a cycling block buster, but consider it for a second viewing if you have seen it. Where everybody knew the basics of the Armstrong story after the collapse of his empire in 2012 and early 2013, this movie shows how much force he used to silence his opponents. What ‘winning at all costs’ really means. As much as it established my opinion about Armstrong being the best of the cheaters and therefore his achievements are still somehow respectable, it mostly left me with a sour feeling seeing the lengths LA would go to to protect the fame and fortune he built for himself. The most interesting parts might be the interviews with Dr. Ferrari, a man who is known to not speak much in public.
Clean Spirit (available on Netflix)
After the doping riddled history of cycling, Clean Spirit shows a new generation of cyclists. It follows the Argos Shimano team (currently Team Giant Alpecin) participating in the 2013 Tour de France. It documents the rise of new sprinting super star Marcel Kittel, who beat Cavendish and Greipel multiple times and we see a young Tom Dumoulin and John Degenkolb as parts of Kittel’s sprint train.
The most impressive part for me was the famous takedown of Tom Veleers by Mark Cavendish in full sprint. The aftershock of Cavendish apologizing via Twitter, but not willing to meet Tom face to face is shown in great detail.
One of the OG freeride mountain bike movies on a larger budget. This movie predates the wide acceptance of action cameras, so the directors got very creative. Cameramen hanging from zip lines, setting up rails in the forest. It’s all amazing. Watch this trailer first to get an idea of the behind the scenes work involved in making one of the best freeride films in history: https://youtu.be/bjuAUTarbdA
Here’s a look into the heart of Flanders. It’s known fact that Belgium has cycling flowing through its veins. The 9 episode series was shown on national television, telling stories about the lives of several families on the day of the 2010 Tour of Flanders. It’s dark humor, mixed with touching stories and amazing cycling footage. The directors had access to place cameras in several team cars and got the Sporza presenters to act in the show. Everything just flows perfectly between the race footage and the fictional story. The first episode is a bit slow and many characters are introduced, but as soon as the race kicks off it’s al gogogo. Subtitles are available on youtube.
Disclaimer: European TV is very liberal. Even though this show was broadcasted on national tv at 8pm, please don’t come knocking on the Kogel Bearings HQ door if you’re offended by images that would have to be shown on HBO in the US
Part of a reality show called Superfans, Frans is not a fan of Eddy Merckx, he thinks he IS Eddy Merckx. The two clips kick off with Frans mixing raw egg and Flemish sour beer for breakfast, just like Eddy. Frans shows his Eddy Merckx replica bikes and jerseys and how he rides the indoor trainer like Eddy. The second clip shows Lookalike Eddy gluing a tubular in 30 seconds, racing his orange bike across the cobbles just like… well you get the idea. Unfortunately, no subtitles on these clips, so you will have to sit through the parts of the wife frustratedly saying ‘I married Frans, not Eddy’, but it’s a good watch.
The same Superfans series followed fans of Sven Nys and how they dedicate their lives to chasing their hero to the races and on training loops. I’m sure you can find it with a Google search.
Ride the Divide (available on amazon prime for a few bucks)
The longest mountain bike race in the world stretches 2700 miles from Canada to Mexico, following the Rocky Mountains. The race is non-stop, so whoever sleeps is losing time. Brutal! The race footage is good (don’t expect any Nino Schurter speed climbing or artificial rock gardens), but the scenery is the real winner here.
I hope this is enough footage to pull you off Zwift Island or the Sufferfest videos when its time to cruise through a snow storm.
With all the bottom bracket standards on the market, it is quite shocking that the bicycle industry did not find the one that works perfectly for all applications. At Kogel Bearings we spend a good amount of our day looking at bottom brackets, so I felt it was time to share the pros and cons of all systems with our friends. This information should help you find the bottom bracket and crank combination that best fits your needs.
I’m not here to burn any frame builder for their choice for this or that system, or to push users into a certain direction. Opinions get strong when discussing bottom this problem area of the bicycle, so I have tried to stay objective and Kogel Bearings will keep on striving for the best possible solution given your choice of crank and frame.
BSA-ITA threaded bottom brackets
The good old threaded bottom bracket. Many times on forums people wish they could go back to the days where everything was simple. I argue that it was never simple, with Italian vs BSA, Campy vs. Shimano and all the different spindle lengths, but that’s another discussion.
The fantastic thing with threaded frames is just that: it’s threaded. The cups lock into place and align themselves. Also the system is very easy to remove and reinstall should there be an issue. All modern day set ups have the bearings running nice and wide, so stiffness is never an issue.
The main down sides of a threaded set up is that not all cranks fit. A true BB30 spindle will be too short to make it through the frame. Another problem is that it is not possible to cut threads into a carbon frame. Any carbon frame will need an aluminum bottom bracket shell glued in, which in itself could be a source of creaking and it is a no no for any designer trying to make the frame as light as possible.
Introduced by Cannondale in the early 2000s, BB30 was supposed to increase crank stiffness with it’s ‘bigger than Shimano’ spindles. While that may be true for a shorter and thicker spindle, my experience is that the narrow set up does the exact opposite: the bearings are so close together that the system becomes unstable and power is lost through flex. This narrow build also ramps up the stress on the bearings.
With the standard being designed to make sure the bearings do not fit too loose in the frame, another common problem is bearing compression. The bearings are pressed into an opening that is too small to fit, which causes the bearings to seize up. With this point and the above mentioned narrow spacing, BB30 bearings are known to have a very short lifespan.
On the positive side, if you are looking to ride with a super narrow Q-factor BB30 is your friend.
PF30 was introduced by SRAM as an open standard for anyone to use. It built on the narrow Q-factor of the BB30 but tried to fix a few BB30 issues by pressing the bearings in a cup before they were placed in the frame. The first one is the super tight tolerances that come with a BB30 frame. The PF30 tolerance is four times bigger, which allows the frames to be built with all carbon BB shells. The down side of a larger tolerance is that it is almost impossible to make the cup press perfectly in every frame. Results are creaking and (again) bearing compression, depending where your frame sits in the range.
Shimano’s answer to the press fit craze is called simply ‘press fit’, but more commonly known as BB86 for road bikes and BB92 for mountain bikes. It has the wide set up of a threaded bottom bracket and keeps the bearings in a cup similar to PF30. The system is typically very stable and stiff, because there is a wide BB area that the other frame tubes and grab onto.
A minor down side is that the BB86 shell is smaller in diameter than a PF30, so the down tube can be wide but needs to be flattened where it meets the BB shell.
A big issue with the smaller diameter of the Pressfit shell is that it does not accept 30mm spindles very well. The different solutions that are on the market between Rotor, Enduro Bearings, Race Face and our own, show that the jury is still out on how to tackle this problem. Even though I consider the Kogel Bearings solution best in class, I would still advise anyone to stay away from this combo if you can avoid it.
In our next post we will be looking at BBRight, 386EVO and a few other standards before we try to come to conclusions on all these options.

The good old bottom bracket, the silent work horse, hidden deep down inside the bicycle. Well, silent is referring to the ideal world in this case. With the explosion of bottom bracket and crank standards we have witnessed in the last decade, the bottom bracket has turned into a bike part that seems to be in constant need of attention. Today I will try to find out what led to this situation and if there is a light at the end of the tunnel.
Bottom Brackets have always had their problems
Many times in magazines, articles or forum posts we read that the bottom brackets of today are too confusing, and that is absolutely true. As a former shop owner, I always dreaded the moment when a customer walked into the shop with a random crank and frame in hand. I know I lost 20 minutes at that point: first determine the standard of the frame, then the crank, then try to find the right pieces to fit them in a huge online ordering system.
But has this ever been different? Way back when bottom brackets were still called ‘square taper’, there was Shimano which would not fit with Campagnolo. There was Italian or English and in none of those cases a road BB would fit on a mountain bike. And then there was chain line: I found the right bottom bracket, but need a 118mm instead of a 113mm to keep my crank arms from jamming into the frame.
Pushing the boundaries of bicycle development
After square taper we were ‘blessed’ with ISIS , Octalink, hollow tech II, Ultra Torque, BB30, GXP Power torque and Over Torque. And that is only on cranks! Frames spun out of control in a very similar way with a dozen press fit variations: BB30, PressFit30, PressFit without 30 which is also known as BB86 unless it is on a mountain bike, then it is called BB92 but it might measure 92.5 or 89.5 millimeter depending on the brand.
You lost me somewhere in there? I don’t blame you. Trying to fit a crank and frame seems about as easy as predicting the Euro/Dollar conversion rate for the next month.
The reason for this is that bicycle manufacturers are constantly looking for stiffer and lighter frame constructions. Sometimes this involves true innovations, sometimes it involves innovating for the sake of changing things for the new model year. Heck, one of the biggest players in the industry has used ‘Innovate or die’ as an advertising slogan for years.
Diversification of the bicycle industry
Another trend I have seen in the bicycle industry is a constant diversification. The village bike shop that does everything on two wheels has long vanished. Nowadays there are specialized shops for commuters, road bikes and mountain bikes.
Looking at the car industry, this development has gone much further. It is close to impossible to drive your Dodge into a BMW dealer for an oil change or to replace a light bulb, leave alone if something has gone off in the electronics. This is the auto industry’s way of making sure that the car they sold at low margin will keep coming back to the dealer for expensive service visits.
Along this path, almost every major frame designer is trying to integrate proprietary parts that can only be bought through their dealer network. It is not possible for a Trek dealer to order spare parts for a Specialized frame or Roval wheels.
How can we fix all these bottom bracket fitting problems?
I see a few solutions. The most obvious one is to always buy a complete bicycle from a brand. For the lifespan of the bike you will be replacing parts from the same manufacturers as the one that came in the catalogue. This is a good solution, unless you did not like a certain part that came on the standard build. What if you love your new cross country racing rig, but the brakes came from a brand that is notorious for quality issues? It also takes all the fun out of customizing your bike or completely building it part for part from the ground up.
As for bottom brackets, at Kogel Bearings we see a future in smaller boutique brands that have the ability to do small production runs and be quick to act when new fit issues arise. We pride ourselves in fitting any crank and any frame without adapters. Similar solutions are available from other brands for chain rings and setting up mountain bikes with a non-proprietary 1X drive train.
As long as the bicycle industry runs on creative people and small-time entrepreneurs, you will always be able to find a solution for your problems. It might take a bit of digging, though.
An entertaining view on the bicycle world. Always professional, rarely scientific.
