Chain idler set for Challenge Hurricane

Like all T-Cycle chain idler sets, it promises many worry-free miles with less vibration and greater efficiency for the entire drive train. The set consists of the SPORT drive roller, a stainless steel chain guide and all spacer rings.

CNC machined chain idlers with minimal tolerances mean more efficient power transmission, less noise and lower vibrations. The drive on your recumbent will really benefit from this in the long term. Due to the longer chain on most recumbents and trikes, it is essential to pay attention to high-quality chain guide components. Everywhere else in the area of the drive chainrings and cogs are used. Why should your chain idler be less important? A chain chain idler without teeth, over which a drive chain is guided, causes friction and thus a loss of power. This can be seen from the fact that the chain begins to mill deeper and deeper notches into the plastic material of the chain idler. With a very hard plastic, the chain will constantly bounce up and down, even on its way to the rear wheel. A chain has a very specific shape designed to run on a chainring or cog. The T-Cycle chain idlers are designed with this in mind. They transport the chain of your recumbent bike or trike with a CNC-manufactured cog made of high-quality 7075 aluminum (SPORT version) or made of 6AI/4V titanium (ELITE version).

When deciding between an aluminum or titanium cog, we recommend the titanium cog for strong riders or frequent riders. The aluminum cog offers a long service life, but signs of wear will be visible after several thousand kilometers. We also generally recommend the titanium cog for the small chain idlers. In addition, T-Cycle generally recommends the titanium cog for trikes, since the chain guide here often tends to put more strain on the chain idler and thus on the cog. Incidentally, the power transmission from the deep groove ball bearing via the mounting body to the pinion is completely metal. There are no plastic parts mounted from which the cog could tear off.


The T-Cycle chain idler can be completely dismantled. This means that the bearings can be serviced and, if ever necessary, the pinion can be replaced as well.
With the TerraCycle chain idler you increase the efficiency and reduce the noise of your drive and save money in the long term thanks to the long service life and ease of maintenance!
