Ibis 741 Carbon DT Swiss 27.5" Wheelset

To put it plainly, wider rims are superior to narrow rims. Why? Where do we begin? Wider rims dramatically increase traction, reduce rolling resistance, decrease tubeless "burping", provide a stiffer, stronger, lighter wheel, and plenty more. Let us introduce you to the Ibis 741 Carbon Wheels; wide, lightweight, tubeless, and to the shock of many; modestly priced.

The rims on the 741 Carbon 27.5" measure a gaping 41mm outside width and 35mm inside width. This is one of the widest carbon rims available before you'd be forced to reach for the Fat Bike-specific 50mm rims! As the "new wide", the 741 Carbon wheels provide incredible support to the tire's sidewall, allowing lower pressures without the tire folding over or burping. This significantly increases stability and traction, enabling faster cornering and braking, and better bite in all conditions. Lower pressures also mean lower rolling resistance which equates to an overall more responsive ride-quality.

As hard impacts are the number cause of damaged rims, the 741 Carbon rims are hookless as a means to increase resilience. By eliminating the inverted "J" built into the rim walls, the rim is designed with a solid rectangle in place of the hook, allowing the rim to be much more robust in the area where impacts occur. This spreads the impact out over a larger area that is supported by more material. After extensive testing, Ibis found a 50 €“ 300% improvement in impact strength than competing rims with hooks, without any detriment to tubeless performance and reliability.

Aside from the progressive rim width, the carbon fiber construction has allowed Ibis to build a 475 gram rim, which is lighter than many of the narrower, weaker, alloy rims on the market. Additionally, the carbon build provides a stiffer, snappier platform. The lack of wallowing sidewalls, and the dramatic increases in rim stiffness and contact patch area enables a sturdier planted feel that inspires newfound levels of confidence.

Each spoke hole is individually reinforced with extra carbon to achieve a stronger rim than the spokes, so the rim won't damage if a spoke breaks. The no-BS 741 is built with 32 conventional spoke and standard exposed nipples. This allows the wheel to be tuned without special tools or having to dismount the tire and rim tape. Although, using fewer spokes may have tipped the scale at a lower weight, using more spokes offers superior longevity and trail-crushing stiffness.

This version of the 741 comes complete with a DT Swiss 350 rear hub with a 54 tooth ratchet that'll give you a 6 degree engagement in one of the most highly relied upon hubs on the market.
