Product Details

This idler is a drop-in replacement for the HP Velotechnik idler (our HPVT idler kit includes the necessary spacer to get the idler lined up on your original chain line). It is a nice upgrade for all current (large idler) bike and trike models.
On the Gekko, there are some restrictions. This idler fits and works great in the Gekko except for the fold. The fold on the Gekko twists the chain rather severely right as it goes through the idler. On the stock idler, the chain can rotate in the (extra wide) groove. Since our idlers carry the chain on a metal cog, the chain can’t twist. It is entirely possible to use this idler on a Gekko, but we recommend removing or loosening the chain keeper before you fold, and being very careful to guide the chain as it twists, so it doesn’t grab on the cog or try to wedge between the idler, chain keeper, or idler side plates.
On a very few bikes, the seat mount is sometimes closer to the idler mount than others. If that is the case with you (and it is rare), we can replace the side plates and reduce the size of the idler 2mm.
The cog is precision machined, but there is a break-in period while the cog and the chain get to know each other. After that, you can expect your idler to last many, many thousands of miles before needing service.
This idler is designed for use with 8, 9, and 10-speed chains.
In case of damage, all parts are individually replaceable. Contact us for details.
Stainless fasteners used because we know you don’t want things rusting.
Since the larger cog in this idler shares the wear among more teeth, and because the cost of titanium is high, we offer this idler wth a 7075 Aluminum cog option. The titanium cog option is 6AL/4V titanium, for the ultimate in durability. In all cases, the cog and frame are extensively machined out for lightness.
Bearing Care: The bearings are shielded, not sealed. Shielded bearings have less rolling resistance because the seal, while super close, doesn’t actually rub. Truly sealed bearings are rare when people talk about “sealed bearings”, they usually actually mean shielded. These are top quality shielded bearings and will last a long time. What kills bearings is solvent, dirt, and water intrusion. As long as you don’t spray things on the bearing faces, you will be OK. Regular amounts of dust and dirt getting on the outsides of the bearings won’t be a problem, as it’s hard for it to get past the shields (the shields really do come *very* close to the bearings). When you clean them, what you want to do is gently wipe dirt off and away from bearings, rather than rub aggressively and push the dirt past the shields. There is no need to lube the bearings, the special grease that’s in them is what they need.
No maintenance should be required other than occasional cleaning with a paper towel or soft cloth. We recommend keeping solvents and soap and water away from the bearings, they don’t need aggressive cleaning and solvents and soaps tend to go after the grease. It’s water-resistant, but solvents and soaps are harder to deal with.
You will probably never need to disassemble your idler. Should you ever need to, a 2.5mm Allen wrench is all you will need.
Our largest idler, the 23T is an upgrade replacement for any current HP Velotechnik bike or trike. While this idler fits and works great on the Gekko, the way the chain twists during the fold is not compatible with this idler. Extra steps are required to fold and unfold the Gekko without damaging the idler. There are no restrictions on any other models.
We recommend the kit for HP Velotechnik, it includes a necessary spacer.
