The Shimano DEORE XT BB-MT800-PA is a press-fit bottom bracket built for frames with an 89.5/92 mm shell width and a 41 mm shell ID, using Shimano’s 24 mm MTB crank standard. It’s the right choice when you want a genuine Shimano fit for a compatible mountain bike frame without overcomplicating your build.
On the trail, what matters is smooth pedalling and dependable sealing, and that’s exactly where this unit makes sense. The sealed bearing design and wide bearing stance of HOLLOWTECH II are aimed at solid crank support and efficient power transfer, while the low 58 g average weight keeps things tidy for riders chasing a reliable replacement or a sensible fresh build.
Buy this if your bike is built around a PF41 / BB92-style MTB shell and you want to stay with a Shimano-compatible system. It suits a big spread of Shimano MTB cranks, including many DEORE, SLX, XT and CUES 24 mm options, but it is not the right bottom bracket for threaded frames, road PF86.5 shells, or SRAM DUB / 30 mm spindle cranks.
Ideal for mountain bikers or home mechanics replacing a worn PF41/BB92-style bottom bracket for a Shimano 24 mm MTB crankset.
Made for 24 mm Shimano MTB cranks
Designed to suit Shimano MTB cranksets that use the 24 mm HOLLOWTECH II spindle standard, so matching the rest of your drivetrain is simple.
Fits 89.5/92 mm press-fit shells
Built for compatible MTB frames with an 89.5 or 92 mm shell width, making it a direct option for many modern trail, XC and hardtail frames.
41 mm press-fit standard
This bottom bracket suits PF41-style MTB shells, so shell diameter matters just as much as shell width when you’re checking fit.
Sealed bearing construction
High-quality sealed bearings help keep out water and trail grime for smoother running and less day-to-day fuss.
HOLLOWTECH II support
Shimano’s wide-set bearing layout supports the axle securely for stable pedalling feel under load.
Light overall package
At an average 58 g, it keeps weight low without stepping away from a practical OEM-style design.
Useful Shimano MTB compatibility
This model is listed across a broad range of Shimano MTB and CUES crank applications, which makes it a handy replacement part when you want to stay in-system.
