New Shimano 11-Speed XT 8000 Brings a 42T Cog, Plus More Crank & Axle options

2016 Shimano XT 8000 11-speed mountain bike component group details

Lots of new shiny parts today as Shimano has updated its workhorse Deore XT groupset to the same new 11-speed standard we’ve seen in the current XTR group. Plenty of tech makes its way into the new 8000 group, while still keeping the Trail and Race options that have helped make these upper level Shimano groups successful even as mountain biking specializes itself. Like XTR, the new XT offers 1×11, 2×11, and 3×11 setups with Shimano’s Rhythm Step progression aimed at keeping gearing steps smooth and consistent to maintain ideal pedaling cadence.

Shift past the break for all the trickle-down update details, new crank spindle options and expected availabilities…


Bosch’s Improved eBike Performance Line System, Opinion on eBike Technology

Bosch eBike PerformanceLine lifestyle

Bosch, after only beginning its eBike technological journey in 2009, has released a refined and improved electric system in their eBike Performance Line. The battery lasts longer. The Drive Unit now comes in multiple flavors to better integrate with the bicycle frame as a static chassis and in motion under different types of riders. The sophisticated controls are highly integrated on a level you don’t often see in the product of this industry and are highly user focused from a conscious and unconscious interactive standpoint. There is a reason why it won the Red Dot award for design excellence.

Let’s dig into this new system after the jump…


TPE15: Closeup on new goods from WTB, Powertap, Novatec and Samox

WTB Ci24 carbon fiber mountain bike rims

Two of the brands shown here, WTB and PowerTap, announced their new products just before the Taipei Cycle Show, so we used our time with them to take a few detailed shots and ask more technical questions (of WTB anyway).

WTB’s products were announced just days prior to the show, but all have availability dates this summer. The rims have an interesting production story. They say they’re still playing around with different materials in different places and different manufacturing partners based on where the rims are going to be sold.

The 27.5 rim shown here has a more UD finish (left) on the inside and it’s made in Taiwan. The 29er has the woven top layer and is being made in China. Apples to apples, it’s coming out lighter, hence the eerily close claimed weights for different size rims. They’re still in testing, but Chris Feucht, product development manager, says all aftermarket rims will likely ship from the China factory and that the 27.5″ is likely to see a weight reduction by the time they’re available. The Taiwanese made rims will likely be reserved for OEM customers. So, build your own wheels and they’ll probably be lighter.

The reason for the difference is basically just dealing with the different capabilities and methods used by different manufacturers.


TPE15: Wheeler’s Thirtysixxer towers over slick 29er, cyclocross & other bikes


Wheeler is a Taiwanese brand with distribution throughout much of the world, including a U.S. agent despite the limited presence here. Most of the bikes on their website are mid-level, with a few slick looking full suspension mountain bikes and aero road bikes topping things out. For Taipei, they had several new models across new-for-them categories that featured some nice details.

The Thirtysixxer was rightly placed at the corner of their booth, suckering me in for a closer look…


RockShox Updates Monarch RT3, Introduces Oneloc Remote, Maxle Stealth, and RS-1 27.5!


It may not be the new Bluto based on a 34mm Pike chassis you were hoping for, but RockShox has a number of smaller additions that are sure to make a number of riders excited. Starting with the Monarch RT3, RockShox’ popular air shock receives a number of internal improvements to make the ride even better. Meant to give the shock more control, adjustment range, and better traction and lockout feel, RT3s will see a new compression piston, poppet valve, and rebound circuit. Thanks to the new piston, compression forces are lessened at high speeds allowing better control over the oil flow. Rebound is improved as well with an additional shaft port for the beginning of the stroke and a dual taper rebound needle which again increases the oil flow for more adjustment over a wider range. The new poppet valve includes an o-ring and riveted shims which makes a better seal and results in a more positive feeling lockout.

Available in May in all standard Monarch RT3 sizes and air cans, the new RT3 design is just one of a number of new additions…

Review: Renthal Launches New 1XR Chainring


While Renthal is probably best known for it’s dominance in powersports, in recent years the UK based company has released a slew of new products (in their trademark golden hue) for the cycling market. The latest addition to their product line is the new 1XR Retention Chainring, which was developed specifically with British weather in mind.


NAHBS 2015: Savvy Cycles shows wood a good time


Savvy Cycles is the brainchild of Mike Mahoney, who brings his diverse background of woodworking skills to frame building. From longboard skateboard manufacturing to teaching woodworking, Mike has spent the last two years perfecting the process of making the wooden bicycle frame. Mike’s primary woods of choice for frame construction are hickory and ash, known for their strength, durability and ability to be steam bent. Woods such as sepele and dyed hard maple are used for frame accents.


TPE15: New Vittoria MTB tires cover XC to DH, plus a look at graphene carbon rims


Last year, the Geax line of mountain bike tires was rolled into parent brand Vittoria. Most of the existing models carried over, and the Peyote, Barzo and Jafaki are the first three new treads to roll out under the Vittoria name.

The Jafaki is a moto-inspired tire with big knobs and even bigger side knobs to keep your firmly planted during high speed (read: descending) maneuvering. The widely spaced center section should clear quickly, making it a solid choice for enduro on anything but very dry hardpack.

The Barzo and Peyote skew more toward all purpose trail and XC use with lower profile knobs and faster rolling center sections. All three tires use sipes on the tread blocks to improve grip.
