WIPEOUT 1000

John Apparently, you can e-mail TeamHOTSHOT for the more information on their scientific claims, but I am sure that you know a lot more about cramps than I do. The only point I really wanted to make, and I do appreciate that my personal experience is anecdotal, is that for me (and a couple of my friends) doing long distance events (e.g. 600km Radonnee's, PBP, etc.), pickle juice and specifically pickled onions has provided relief from exercise induced cramping. Furthermore, if anyone wants to give it a try, it’s cheap and easy to try out.

A couple of years ago a couple of scientist (Dr. Rod MacKinnon & Dr. Bruce Bean), discovered that muscle cramping is triggered by hyperactive nerves that can get over-excited with exercise and repetitively fire into the muscle. In short they developed a product "HOTSHOT" that is the only scientifically proven product to prevent and treat muscle cramps. They claim that it basically resets the over-exited nerve. From my experience it's more a case of that if you suddenly experience a greater discomfort, you're body kind of forgets about the the lesser one. In this case if you eat a really hot chilly and your mouth's on fire, the cramps tend to go away. HOTSHOT, is also the product Tadej Pogačar used when he started cramping in the last couple of km's of the 2023 Giro di Lombardia. I've used it and it's basically a variation of pickle juice and it taste like pickle juice blended with apple juice. I have found that as a alternative, hot pickled onions work really well for me, I buy them then I add some extra chilly powder. The nice thing is that you put a couple in a zip lock bag and eat them either before or as you start cramping. I find that chewing gives a longer burning sensation.

Cycle it often on weekends. If you’re concerned about Helshoogte, try finding a riding partner/s. Winelands cycling club often do escorted group rides on weekends starting from Waterstone.

Really depends on what product you use or intend using. Most are primarily a combination of latex and glycol plus some form of filler to assist in blocking the hole. Rule of thumb, the higher the latex % the quicker it will seal, but also the quicker the sealant will dry out. E.g. a "race" sealant will seal quicker but also dry out quicker. Josh Poertner from Silca suggest you do a basic shake test, if you can hear it sloshing inside it is probably still fine, if you cannot you need to add/replace.

I did it with my cousin in 2015, amazing experience, so many emotions, so many awesome memories, so blessed that I could finish it.

Just got the e-mail message that that GCN+ will soon be closing. Not sure how I feel about it, I only really used it to watch events.

Go tubeless 🙂, but should not be problem at all.

You're not alone, well known problem. Peak Torque made a video 3 years ago.

Pinion gearboxes have the same drag penalty as Rohloff hubs but I agree that if I was riding a Pyga ebike, I would also not be that concerned about drivetrain efficiency

Owned a Rohloff hub and as great as they are for reliability and maintenance, they're always a couple of percent less efficient than a 2x set-up even if you completely cross chain. The same applies for the classified powershift system. When you're in the climbing gear, you basically get the worst of both worlds, i.e. the additional drag of the planetary gears combined with the additional drag of extreme cross chaining.

I really like the ability to change gears quickly and this probably the primary reason why I ride Campagnolo on my road and gravel bikes. Being able to drop 5 or go up 3 with a single shift is really convenient. Other than the efficiency thing, it is also one of the main reasons I still ride 2x on my mountain bike, by dropping from the big ring to the small ring you can instantaneously increase your mechanical advantage by 30+%.

Exactly, I just need some carbon fiber waste to chop up

For the most, with great difficulty. However, SILCA chops it up, bakes off the resin and then adds the chopped strands to their sealant (SILCA Ultimate Sealant w/FiberFoam). Apparently it works really well, just can't buy it locally . I would not mind trying to do something similar with the aforementioned rim.

Because of the gearing, the unit to use should be power i.e. Torque x Angular Motion. I do not know how efficient the the planetary gear system in a Classified hub is, e.g. if it was 97% efficient and if you could ignore the losses in the chain (impossible, but only to illustrate), it would mean that if you applied 300W on the crankset, you would loose an additional 9W on the rear wheel. Try improving your FTP by 9W.

Yes and when he used it, he used a modified front derailleur as a chain catcher https://bikerumor.com/campenaerts-races-classifieds-internally-geared-hub-w-62-tooth-chainring/

A chain catcher can achieve exactly the same outcome, it attaches to the front derailleur hanger, has no moving parts, weighs basically nothing, is really cheap and most importantly works. Even when Wout van Aert rode SRAM 1x during the 2023 Milan San Remo, he still used a chain catcher.

Solving 1 perceived problem (the front derailleur) with a multiple of others. All things being equal, a couple of obvious negatives that come to mind: Mechanically, it has more parts and is significantly more complicated that a standard hub and front derailleur combination The planetary gears in the Classified hub has to be less efficient than a standard hub It forces one to cross chain, which is again less efficient It is proprietary, if you break a wheel you have a problem It is not clear to my how one integrates it into an existing ecosystem (e.g.DI2, AXS, EPS) It is significantly heavier than a standard freehub It is really expensive compared to the alternatives In summary it a proprietary solution that is more complicated, less efficient and heavier than the obvious alternative. The only question I have is why?

I am graduate mechanical engineer with more than 30 years experience in the design, building, operation and maintenance of mechanical plant & equipment and from my perspective the issues PT raised are legit. What type of engineer are you and how does that make you qualified to claim that everything PT said had no engineering merit and is just pure emotion? Do you possibly also ride SRAM?

I am aware that the majority of millennials and Gen Z’s generally form their opinions on whatever is trending on social media and/or what the Google/Youtube algorithms pushes to the top. Furthermore, I appreciate that everyone is entitled to his own opinion, but as the saying goes “not his own facts.” In this case, if you want to make a constructive contribution to this discussion, I suggest you consider a bit more science/engineering and less marketing hype. I’ve attached a link to an unsponsored video, explaining why this is truly a very poor engineering solution. “Mechanical Engineer's Opinion of new SRAM Eagle” https://www.youtube.com/watch?v=rDxgxHiijF0

If you've not bent a derailleur hanger your either very lucky and/or you've not been cycling that long. I've bent and/or destroyed at least 3 or 4 derailleur hangers and my son has done 2 in the last year. Furthermore, I have also had the misfortune of destroying a frame in the mid 1990's because back then the derailleur hangers were part of the rear dropouts and a branch on a trail ripped my derailleur clean out of the hanger, not only destroying the hanger, but also bending the rear triangle. Without getting technical, i.e. getting into impact forces, levers, bending moments, yield strengths, etc., you'll be surprised how easy it is to bend/break a 12mm hollow aluminum thru axle.

Agreed, yet, another example of how SRAM "innovation" provides the customer with a worse outcome. Why just bend a derailleur hanger if you can break your frame?

I've done 20 000km on a single chain with less than 0.5% elongation using standard paraffin wax and a cheap slow cooker. It's neither complicated nor expensive and it definitely faster and cheaper than any chain lube that comes in a bottle.

Waxed chain, they all shed wax initially.

I have not bought one locally but I suspect you should be able to find an Angleset in SA. You can also also look at these: https://www.workscomponents.co.uk/ https://www.wolftoothcomponents.com/pages/geoshift-angle-headset https://www.superstarcomponents.com/en/slackerizer-angle-headset.htm

I owned one of these and mine had a 120mm fork, but if I had to change anything else, it definitely would be installing a Cane Creek Angleset (or equivalent) to slacken the head angle a bit.
