FiBROUS 29er, 27.5er and 26er Carbon MTB frames


This frame can be custom built by FiBROUS to suit your needs. We can help you work through the huge selection of build options available these days, so you get your perfect setup straight away, at a very competitive price. Please drop us an email or call to get the ball rolling.  And of course the frame is available by itself for your own project, or to upgrade your current bike.   The build service is free of charge, as part of the purchase of a frame.

The 26er, 27.5er and 29er carbon hardtail frames are super lightweight, as well as stiff where they should be and flex where they should, too.  Confidence-inspiring rides with dialled geometry.  Covered by a lifetime warranty.  The frames feature:

- Optimum chainstay length.  The width of the BB92 bottom bracket not only creates a huge interface with the downtube, it also allows these frames to bring the rear tyre closer behind the bottom bracket than ever before.  The chainstays range from 420mm for the 26er to 429mm for the 27.5 and 29er, which have been found to offer the best handling on the trail through decades of mountainbike development.  The 429mm chainstays on the 29er are exactly the same as Cannondale's latest and extremely expensive "Ai" hardtails, which they have designed components specific to the design (read: very expensive upkeep) to create what is claimed to be the "shortest chainstays on the market".  Make that " equal shortest chainstays on the market"!

- Extremely solid headtube, downtube, bottom bracket and chainstays.  Stiffness is paramount in the lower parts of the frame, particularly the connection to the fork, cranks and rear wheel.  So these areas have had their proportions boosted and carefully shaped.

- Upper tubes on the frame are more modestly proportioned, especially the thin seatstays that allow some of that trail buzz to be absorbed (but let's face it, our tyres are going to do most of that job - in fact, many people are finding that with the latest larger tyres running tubeless on wide carbon rims like on the FiBROUS 29+ wheels, they have all the comfort and traction they need, without the complication of dual suspension).

Supplied with headset for use with either tapered or old standard 1 1/8" fork steerers.  Suitable for forks up to 130mm travel right down to rigid forks - matching 29er fork available  (495mm axle to crown length), which may be suitable for the 26er and 27.5er as well, depending on your desired geometry.

Shipping is worked out for each individual order, to offer the best value and security.  We can offer most South Australian orders a free personal delivery, or a meeting place arranged.

All three frames have "through axle" or regular 135mm quick release rear hub compatibility options. Please specify whether you would like the quick release, through axle or request more information in the box below before adding to cart. The finish is also optional - you can choose either matte or glossy finish on top of either a 3K or "UD" finish. 3K matte is the default choice for these frames.
