Campagnolo's Record EPS V2 Power Unit is the reliable brain of Campy's electronic shifting. In order to keep your bike looking sleek, the mounting options allow it to sit inside your bike's frame. The 3-cell, 12-volt Lithium-ion battery delivers up to 1,200 miles on a single charge. It also houses the electronics necessary to deliver pinpoint shifting precision to the front and rear derailleur mechanisms (sold separately). For example, if you're cross-chained, the system immediately senses it and moves the front derailleur ever so slightly to avoid chain rub. Plus, the one-piece, ultrasonically-sealed unit is impervious to water or road vibration.

The EPS Power Unit is the systems source of power as well as the "brain" of the system, responsible for managing the battery pack, enabling and monitoring the front and rear derailleurs and communicating with the Interface Unit. - Weathertight, o-ring sealed connectors - Lithium Ion battery duration: 500km/month - 1500km, 1000km/month - 1800km, 2000km/month - 2000km - Water proof to 1m for 30 minutes (IP67 Rated) - Operational temperature: -4F to 140F - Charging temperature: 32F to 113F - 17mm diameter for easy seat post installation - Battery charges through the Interface Unit - Compatible only with the Super Record/Record V3 Power Unit

All CeramicSpeed Bearings are hand-built in Denmark. Super-smooth CeramicSpeed grade 3 Silicone Nitride balls are matched (within microns) with hardened steel raceways that feature an ultra-smooth polished groove. The balls are held in place by a reinforced polyamide cage. Every bearing is optimized with a low-viscosity CeramicSpeed All Round Grease to minimize friction and increase bearing life. Non-contact seals complete the bearings, keeping dirt and moisture out. CeramicSpeed Bearings can be used for any cycling discipline: Road, TT, Tri, Track, Cross, and MTB. The benefits are super low friction, better power transfer, and increased bearing life. During the building process, we check each bearing four times by hand to ensure that all parts are matched perfectly. CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel bearings normally used in the bicycle industry. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads, and are 100% smoother. - Inner Diameter: 17mm - Outer Diameter: 30mm - Width: 7mm

The ReMote BarCentric is a dropper lever option for bikes with front shifters, lockout levers, or e-bike controls. The slender design of the ReMote BarCentric allows it to easily fit between the left grip and levers with four potential lever positioning options to avoid any interference with existing levers. This dropper lever has a ring shape that encompasses the handlebar, while also serving as a pivot point to provide the rider with extra leverage, making it easier to press the lever. - Compatible with left side controls including 2x shifters, suspension lockout levers, and under-bar e-bike controls - Large, smooth, sealed Enduro ball bearing that encircles the handlebar - Clean and efficient cable routing flows around disc brake levers - Adjustable reach for ideal ergonomics and controls clearance - Compatible with all cabled actuated dropper posts - Works with dropper posts that have the barrel end of the cable at the remote and those that have the barrel end at the post - Works with any mountain bike handlebar - Can be rotated to your preferred position

ReMatch adapters are designed to integrate different generations of Shimano Brakes to Shimano Shifters. Rematch Adapter 1.2 connects Shimano I-Spec A/B brake to I-Spec II Shifter. - Made from CNC Machined T6061 Aluminum - Anodized Black - Includes all necessary hardware for both I-Spec A and I-Spec B brake - No additional hardware needed

Wolf Tooth ReMote Light Action has a longer lever arm than the standard ReMote and is optimal for dropper posts with a harder pull or for riders that just prefer a really light actuation feel. It reduces the force to actuate a dropper by nearly a third of the standard ReMote. Based on rider feedback and tailored to work with some posts' stiffer internal springs, the ReMote Light Action is also the choice of those with thumb injuries or reduced hand strength. - Upfront cable fixing - Large diameter ball bearing - Cable-kind clamp - Low-profile, light action - Integrated cable adjust - Breakaway axle pivot - High-traction lever - Broad compatibility

Wheels Manufacturing hangers are stiffer than almost any OEM hanger, which improves durability and shifting performance. - OEM hangers are only produced by a handful of manufacturers, mostly in Taiwan and China. As a result, you will see many bikes with exactly the same hanger. Bicycle manufacturers may make mid year changes. Please use the hanger photos to select the proper hanger for your application. - CNC machined 6061 aluminum - Black anodized finish - Made in the USA

The Problem Solvers Cable Doublers are made of light, durable machined and anodized aluminum and they are Teflon coated for a super-smooth cable pull every time. They come in two models. The first allows you to control two brakes with one lever. The second allows you to control one brake with two levers. Why? Well, there are myriad applications: tandems, cyclocross bikes, fixies, tricycles, recumbents, cycles for those with special needs, bike polo bicycles, those 4-person bikes you see on beach boulevards, and so on. You could even link both models of Cable Doublers together for the ultimate in redundancy!

RockShox's Maxle Lite is a lightweight aluminum through-axle system.
