“Last year, South Africa’s Greg Minnaar (Santa Cruz Syndicate), a three-time UCI World Champion, won a record extending 20th Downhill World Cup in Fort William, Scotland. What made these wins unique was that they were the first World Cup events to be won on a bike with 29″ wheels<\/strong>. (..) So does this mean the debate is over, and 29″ wheels have replaced 27.5″ ones? Not so fast!<\/strong>“<\/span>— Thinking about wheels? Michal Cerveny [UCI news<\/a>]
\n<\/em><\/p>\n

As my trusted old Cube bike died due to age (profuse hydraulic leaks, spare parts > 1 month away, while on bike holidays) it was clear I had to replace it. So I bought the useful (but not overly expensive) CUBE ACID, with 29″ wheels, model year 2019, for something over 900 Euros. The dealer gave me a lower price than the indicated \/ recommended one.<\/p>\n

More history is here [link<\/a>] with my coolest bike mod so far being the Colnago road bike with switched Ultegra levers [link<\/a>].<\/p>\n

      <\/span>Overview<\/span><\/h1>\n

      The frame is not very large, but the bottom bracket (Tretlager) sits slightly lower than the wheel hubs. With a 29 wheel size, one almost sits “between” rather than “on top” of the wheels. So, this consideration is not at all about speed: as right below elbow amputee, I wear a prosthetic arm to hold the handle bar on the right.<\/p>\n

      <\/span>29″ vs. smaller wheel size with regard to asymmetric balancing and stability from energy \/ fitness view<\/span><\/h2>\n

      Stability for me is not just as easy as it is for two handed people as we found out over so many rides or trails.<\/p>\n

      There, to me, the larger wheels feel certainly like a considerable improvement in overall stability particularly for riding with asymmetry and consequential issues for stability – not when riding to the post office or to get milk at the gas station. But I particularly notice that I use far less energy to stabilize the bike on steep ascents<\/em>, where a lot less core muscle work is required and more energy can be used for uphill riding. Also for very steep descents the larger wheels are easier to handle for me, balance wise. For peaceful straight level rides, any difference between 29″ wheels and smaller may be negligible.<\/p>\n

      <\/span>Sitting position on bike<\/span><\/h2>\n

      This is the overall view of how I ride the bike. I typically use the Toughware Equilux [link<\/a>] as that device has both Voluntary Closing *and* Voluntary Opening options. Also, it’s shape follows the Trautman hook [link<\/a>] after which it was at least remotely modeled – and that means that even with a Voluntary Opening setting, you can comfortably idle or seriously ride the bike but forces of the handle bar won’t pry open the hook device. So you can ride, safely and perfectly well, even by just using\u00a0 the passive setting so to say.<\/p>\n
