ADDITIONAL INFO

• Compatible with 7, 8, 9, 10, and 11 speed chains.
• Not compatible with flat top chains.
• In case of damage, all parts are individually replaceable. Contact us for details.
• Available with ABEC-7 bearings with either an 8mm or 10mm bore.
• A third bearing can be added to the return side for the rare applications where that is necessary.
• Precision machined 7075 Aluminum cog.
• All metal core cog-to-bearing construction means the chain loads are carried in metal all the way to the bearings.
• The fasteners are stainless steel M4 x 25 socket head cap screws and M4 nylock nuts.
• The urethane chainbed is very durable, but can be affected by strong solvents. Dumonde Pro lubes apparently have such solvents in them. All the other lubes we and our customers have tried are okay. We don't recommend using Dumonde Pro series chainlubes with this idler.
• Outer Diameter is 2.75in (70mm)
• The Sport Over/Under Idler weighs 108g with the 8mm ABEC 7 bearings.
