Yes, it is possible to dramatically improve stiffness and ride quality, and take a chunk of weight from your wheels with one upgrade!  The construction of the rims produces a wheel that doesn't flex laterally when putting down the power (something that you're probably just used to, unless you've ridden good carbon wheels).  The mtb rims here range from wide to very wide, which has the effect of boosting the size of your tyre without the weight penalty.  It also provides a much more secure hold on the tyre, making it more resilient to squirm/rolling.  And the wheels are generally much lighter, too.

Wheels can be built with the mtb rims listed below, or any of the road rims listed on the other wheels pages (i.e. from 24mm to 50mm and a variety of widths and shapes).

Cyclocross wheels can be built with any road rim (25mm width recommended) or the 30x30mm 29er rim below.

Maximum pressure for the mtb rims is 65psi.

29er wheels:

30mm wide x 30mm Carbon Disc Wheelset
 - Weight: 1480g
 - No holes in the tyre bed, for easy perfect tubeless without the weight and trouble of rim tape and strips.

35mm wide x 25mm Carbon Disc Wheelset
 - Weight: 1590g
 - Built tough for serious all-mountaining.

50mm wide x 25mm Carbon Disc Wheelset
 - Weight: 1740g
 - For big 3" 29 plus size tyres.

27.5er wheels:

27mm wide x 23mm Carbon Disc Wheelset
 - Weight: 1390g
 - Lightest clincher rim in the FiBROUS range - 340g!  The fastest climbing mtb rim in the world, while maintaining decent width.
 - Also an ideal rim for a 1.5" road/gravel/hybrid tyre - the extra weight of the tyre can be completely countered by the weight savings in the rim compared to most carbon road rims, so you get the lovely ride without the weight penalty!  Match this with the FiBROUS ONE frameset for an extremely high performance endurance/gravel racer or tourer!

(There are a couple rim widths between these two, so please message us to find out more about them.  The 27.5er rims listed here were deemed to offer the best width and features to weight ratio)

40mm wide x 30mm Carbon Disc Wheelset
 - Weight: 1590g
 - No holes in the tyre bed, for easy perfect tubeless without the weight and trouble of rim tape and strips.

26er wheels:

33mm wide x 30mm Carbon Disc Wheelset
 - Weight: 1490g
- No holes in the tyre bed, for easy perfect tubeless without the weight and trouble of rim tape and strips.

(There is also a narrower and lighter rim available, so please message us to find out more about it.  The 33mm rim with no holes was deemed to offer the best width and features to weight ratio.  If you are interested in saving weight, we suggest going down a size of tyre, because using this rim will give your tyre more capacity anyway)

FiBROUS uses reliable, lightweight and adaptable hubs from Bitex. They feature a very fast 54-point pickup on the freehub. They are also very adaptable:
 - On the rear, we are able to swap in 142x12mm, 135x12mm and 135x10mm through-axles, as well as 135mmQR (traditional standard quick release).
 - On the front, we are able to swap in 20mm, 15mm and 9mm through axle end caps, as well as traditional QR.

Or we can use any hub you want (with any number of spokes). We can do builds with DT Swiss, Extralite and Novatec at particularly competitive prices (Novatec is a no-cost option, but there is no avoiding the fact that DT Swiss is more expensive and Extralite comes with a bicycle exotica pricetag!).

Spokes are 28x (front and rear) Sapim D-Lights for mtb wheels or bladed spokes for Road disc and Cyclocross.  Custom spokes are possible - please message us to find out more.

FiBROUS rims and wheels are made to order. Build time is usually about 3 weeks. We realise this is quite a while to wait for your fancy new wheels, but this is how we are able to offer a huge range of build options. On top of the rim and hub options, there is the option to have your wheels custom-spoked. If you know you are particularly brutal on your wheels, we can use thicker gauge spokes. There is a box below to enter this preference (if any). Telling us your weight and/or riding style (e.g. XC, AM or DH) will help as well, if you like (heavy riders are well catered for by FiBROUS, just let us know!). Alternatively please leave a contact number/email to discuss rim, spoke or hub choice in more detail.
