WTB Announces Bridger 3.0 27.5+ Tires, Asym i29 and i35 TCS and Ci24 TCS Carbon Rims, and SL8 Saddle

Taipei International Cycle Show

WTB received two design and innovation awards today for the WTB Trailblazer 2.8 27.5+ TCS tire and WTB 27.5+ System from iF Design today during the Taipei Cycle d&i Awards Ceremony. The WTB Trailblazer 2.8 27.5+ TCS tire is a large 27.5” tire that was designed to fit within existing 29” bicycles when combined with a traditionally wider 27.5” rim.  When mounted and inflated, the WTB Trailblazer 2.8 27.5+ TCS tire becomes 28.6” in diameter, causing roughly a ¼” drop in the bottom bracket height of most mountain bikes.

Additionally, WTB unveiled a new Bridger 3.0 27.5+ TCS tread pattern and Asym i29, and i35 TCS rims to further the usage and applications of their new 27.5+ category and tire size

Grams Thoughts => I like the new i29 and i35 rims since I think they’ll roll and maneuver better and make building easier. I am most excited about the new beastly Bridger 3.0 27.5+ tire, which will bring some much-needed girth to the 27.5+ segment, while still keeping it from being a behemoth fat tire. Not sure many 29er frames will be able to fit that big of a tire, but I think we’ll see some new hardtail frames on the market shortly that can accommodate them.

Asym i29, and i35 TCS Rims

WTB Asym i29 and i35 rims will be available in 27.5” and 29” wheel sizes, retailing for ­­$84.95 and $89.95 respectively. Asym i29 27.5” rims tip the scales at 512g with i35 27.5” rims hitting 560g. Both widths feature and asymmetric offset, hence the name Asym, that evenly distributes spoke tension and alleviates the need for dishing during build up. Utilizing WTB’s highest end WT69 Alloy offering, the rims are also directly intended for All Mountain and Enduro usage.

Bridger 3.0 Tire

WTB released a new 27.5+ TCS tread pattern called the Bridger 3.0, and it features an open tread pattern composed of square shaped blocks designed for aggressive riding applications including the enduro segment. “The Bridger shows that we are once again thinking beyond conventionality,” stated Chris Feucht, WTB’s product manager. “Rather than stick within the confines of traditional plus sized tire applications, we are directly targeting aggressive riding.  We are offering the Bridger 3.0 27.5+ tire in a TCS Tough: High Grip option. Sticky Gravity DNA rubber coating a full 2-ply casing begs for technical descents. There is no reason this tire size isn’t perfect for aggressive riding applications.”

WTB TCS Tough tires feature WTB’s Enduro Casing, composed of two full layers of their sealant-optimized Lightweight Casing.  TCS Tough tires are then broken down into High Grip and Fast Rolling options, primarily intended for front (High Grip) and rear (Fast Rolling) uses.

WTB Bridger 3.0 27.5+ tires will be available in TCS Tough: High Grip and TCS Light: Fast Rolling options. WTB lists preproduction weights of 1235g and 1510g for TCS Light: Fast Rolling and TCS Tough: High Grip options with a projected availability of August 2015.  Bridger 3.0 27.5+ TCS Tough: High Grip tires will retail for $76.95 while TCS Light: Fast Rolling tires will carry a $67.95 MSRP.

Ci24 TCS Carbon Rims

After over two years of development, WTB released their new Ci24 TCS Carbon rim which went through five different iterations of design and redesign, settling on the current design after extensive testing beneath Team WTB riders.

There are two things that dramatically stand out with this rim,” stated Chris Feucht, WTB’s product manager. “The 4D angled drilling with chamfer and the true TCS, ETRTO tubeless profile. When you’re dealing with a material as stiff as carbon, it’s imperative that the spokes are aligned properly for departure from the rim. If the holes are just drilled in a standard, perpendicular manner to the rim’s surface, there will invariably be binding and uneven application of stresses. This is especially critical when combined with a material as unyielding as Carbon. The result is broken spokes, nipples, and even hub flanges in some extreme cases. WTB’s 4D drilling on the Ci24 Carbon rims solves binding while still allowing easy access to the nipples for simple tensioning

The second thing is the TCS, ETRTO tubeless profile,” continued Feucht. “It goes beyond just being able to air up with a floor pump, it is wholeheartedly designed around retention, yet still mountable without tools,, you can’t find that in carbon. Now we could go on and on about this type of layup, or that type of weave, direction, or modulus but when it boils down to it, the important thing is it works. We added extra material where it needed it; we thought about the material’s characteristics throughout the whole process. Carbon isn’t for everyone – once you ride it, you don’t want to go back, but understanding that distinction is important. What we’ve done is made our Ci24 Carbon rims as strong as possible while staying true to that understanding that for certain applications or riders, alloy may be the better choice.

WTB Ci24 Carbon rims come in 27.5” and 29” options, weighing 414g and 420g respectively. The Ci24 rims feature a 30mm outer width combined with a 24mm full TCS profile inner width and have an overall depth of 31mm. Available only in 32 hole configurations, the rims carry a $549.95 USD MSRP with an aftermarket expected availability of June 2015.

WTB SL8 Saddle

The WTB SL8 saddle is WTB’s lightest production saddle to date, weighing 146g in its carbon level offering. While the SL8 is not marketed as a road or mountain specific saddle, it takes design cues from fellow WTB saddles. A long tapered nose shares similarities with WTB’s popular Silverado shape and a very slight rise to the tail is reminiscent of the Volt saddle. The SL8 saddle utilizes WTB’s highest end DNA padding throughout its offerings, putting a premium on support through lightweight padding.

WTB SL8 saddles have spent the last year in development and testing underneath Team WTB riders Jason Moeschler, Mark Weir, Ben Cruz, and Marco Osborne as well as fellow Cannondale and WTB athlete Jerome Clementz throughout the past race season with Enduro World Series stops as well as the Big Mountain Enduro Series. Team riders used SL8 Carbon models throughout racing and development.

WTB SL8 saddles will be available in Carbon, Team and Pro models ranging from $119.95 for the Pro to $249.95 for the Carbon option. SL8 Carbon saddles use WTB’s 7mm by 9mm oval shaped Carbon rail, are compatible with top-down clamp seatposts and have no weight restrictions. Projected availability for all SL8 models is June of 2015.
