The handlebar tape shipped with the SB20 is narrow, thin and relatively stiff .  This type of tape was chosen for one important reason: You can route the tape around the remote buttons  (a.k.a.,  sprint buttons ) without causing large gaps.  This style of wrapping works best on the curved portion of handlebars. Wrapping with New Tape In this post, I will show you how to wrap your handlebars with conventional foam tape. Difficulty Wrapping handlebars is easy. Trimming holes for the remote shifters makes things a little bit harder.

The Stages SB20  indoor smart bike was released in 2020. Let's take a look its electronics and drivetrain components. Updated in February 2026 🎉 An external power supply routes power to different bike components through a series of printed circuit boards (PCBs). The bike also includes two battery powered crank-based power meters.  Key internal drivetrain components include a bottom bracket and electronic flywheel brake.  Here's an overview of the basic components: USB Board - Wedged vertically under the phone tray. It powers 3 USB ports. Upper PCB - Fastened horizontally under the phone support rail. This System On a Chip (SoC) handles wireless communication and controls the bike itself. Switch Board - This wire distribution board sits inside the aluminum handlebar stem. It routes connections for the brake level controls  and under handlebar tape "blip" shifter buttons.  Lower PCB  - This mainly analog circuit board is attached to the flywheel / e...

Previous posts describe how to add grease to the large Flywheel Bearings in the SB20.  This post shows how to replace them. I used 6910ZZ bearings that cost less than $15 each.   See the FAQ below for a discussion on using name brand versus generic bearings . Video Here's the video. __________ Flywheel Bearing Removal Steps Replacing Flywheel Bearings  requires the following steps: Perform Flywheel disassembly as described in SB20 - Advanced Flywheel Servicing .   Remove Coils and Optical Sensor .

Making Your SB20 Flywheel Easier to Service When replacing or servicing the Stages SB20 Flywheel Bearings , a few questions are commonly asked: Loctite adhesive is recommended to glue bearings in place. Where should it be used?  Can you over do it?  Can you skip the Loctite? Reassembling the drive-side axle can be difficult. There is not enough room to insert a cone wrench to properly tighten the flange and lock nuts. This means the flange nut can come loose allowing the entire flywheel to potentially move.  What can you do ? Video Here's the video. This post expands on my previous  Flywheel Servicing posts and videos: SB20 - Advanced Flywheel Bearing Servicing SB20 - Flywheel Cog and Axle Bearing Service Stages SB20 - Drive Belt Adjustments (2025) _____________________ SB20 Flywheel Bearing Design The design of SB20 flywheel relies on some basic principles: The axle and flywheel bearings expect an  interference fit  on their outer rings .
