I'm plunking 2000 bucks on a Montague Shimano/internal gear hub bike, use a carbon belt line no chains. These need low maintains and last forever. I am new to the internal hub...has anyone owned such a bike and if so what's your reviews on it.
FABIAN, IM USE IT LIGHTLY ON ROAD. IM GETTING THE 11SPEED HUB SHIMANO. IM HOPING THE NEW BELTS ARE BETTER WITH THE TENSION ISSUESI also need to mention about internal hubs...
If you use them for commuting they're perfect. But looking at the style of your bike, if it´s a moutain bike, and your intention is to climb moutains and give them rough times... I don´t know if I would go for a Shimano 8-speed. Those hubs are reliable for "normal" use but not for abuse like Rohloff are built for.
Rohloff seems a bit less coveted than the shimano hubs..supposely they louder and bit heavier.In 2011, I owned a VSF (german company) bike with such a belt, coupled with a Shimano Nexus 8. I had an extensive use with this bike. That was a trekking bike by the way.
The belt technology works, I find it as reliable as a chain. Harleys use such belts too!
However, belts do tend to loosen up a little with time, and need tension. On the bike that I had, the tension had to be done by ajusting the buttom bracket. I don´t know exactly why, but I always had gear shifting problems due to the lack of belt tension. My mechanic thought it was a design flaw, and was convinced that an ajustment from the rear axle would have been more stable.
I ended up selling this bike, and returned to a classic chain + internal gear hub. Never had a problem since then.
So... I guess it depends how the design of the tensioning system is. I love internal hubs (had a Speedhub Rohloff for trekking, now I have a 7-speed Shimano built on a Gazelle dutch bikefor commuting), and those hubs work great. But my experience with the carbon belt system hasn´t been so good.
