Trialtech SL Ti ISIS with Bolts

New superlight Titanium BB from Trialtech!

- Trialtech's SL Titanium ISIS BB, now with updated crank bolts!
- The Trialtech SL BB's axle is constructed from 6Al-4V Titanium to keep weight down whilst maintaining great strength and durability.
- M14 axle has a thicker wall than most competitors M15 axles, making it stronger and more durable.
- Internal butting on the axle also helps shave off excess grammes.
- Fitted with a lightweight 6061 aluminium shell and cups.
- Axle spacers are designed to be easily removable - allowing almost all 20-spline BB tools to fit easily - as well as sculpted to match the profile of the Trialtech SL ISIS Cranks.
- Full compliment sealed bearings offer improved static/dynamic load capacity and durability. Each bearing has a unique design allowing almost twice the number of balls as normal, thus twice the load capacity. In testing, these single row bearings out-lasted double bearing units seen on other similar bottom brackets while being lighter!
- The BB comes complete with Trialtech's custom CNC-machined alloy M14 crank bolts which are now slightly longer, allowing for a longer thread contact, and feature cool, laser-etched "SL" logos.
- To make fitting the BB as easy as possible, it is supplied with a sachet of anti-seize paste.
- The tough anodised silver finish is complimented nicely with black SL graphics to match the rest of the SL range.
- Only available in 68mm x 128mm.
- Weight: 180.0g (Plus crank bolts at 14.5g)

Please note: When fitting axle spacers, the wide end must face outwards away from the frame as shown in the pictures. Incorrect fitting of the spacers will void the warranty.

Additional Information

Important: Always use copper grease on all surfaces contacting the titanium axle (cranks bolts and crank arms).



Would this bottom bracket fit the monty m5?

Hi Jonas - thanks for your question. Yes, this would fit your frame, but you might have to add some spacers between the frame and drive side BB cup, and between your crank and freewheel to get your cranks and chain to clear the frame. If you need help with which spacers you might need, please get in touch via email (tartybikes@gmail.com) and we will be able to reply in more detail. Hope that helps. Thanks, Flipp.


What are the axel spacers for? I figured them for dust guards - are they required? They actually seem to prevent a firm mount of the crank

Hi Vince - The main job of the spacers is to stop the crank from bottoming out on the ISIS splines. ISIS axles have a very slight taper on them, so if your cranks are pressing against the axle spacers and aren't feeling tight then it could be your cranks are old/worn. This would mean the interface will have worn or stretched a little, and consequently don't fit as tightly as they would from new. Thanks, Mark
