First Look – Shimano Flat Mount hydraulic road disc brakes debut, new 11-speed 105 Level hydro shifter & more!

Shimano BR-RS805 flat mount hydraulic road bike disc brake caliper

There has been a lot of speculation since Shimano first announced a new brake mount specific to road, but little in the way of details. Ironically coming on April 1st in Japan, Shimano is finally showing their hand and introducing two new hydraulic road disc brakes built specifically for the Flat Mount fitment. Announced along with a new 10 speed Tiagra group and WH-RX010 road disc wheelset, the new BR-RS505 and BR-RS805 disc brakes are non-series components at the 105 and Ultegra level respectively.

We have a feeling we’ll be learning more about these new brakes come Sea Otter, but the preliminary details are after the break…

Shimano introduced a new revamped 10 speed Tiagra groupset today bringing their road tech down to a more affordable pricing level. One of the most major updates is bringing internal cable routing to the shifters. The cranks also adopt the new 4-bolt pattern that, while high-performing, has be divisive especially as it has limited replacement availability at the entry-level. The new 4700 group comes in this new Meteor Grey finish and should be available in shops in June.

Come across the break for details and pics of the new components…


TPE15: Maxxis revamps mountain bike line, new fat bike tires, gravel, road tubeless & more!


Updates across the entire Maxxis range touch every discipline, from mountain and fat bikes, to road tubeless and tubular, to new gravel options. Only cyclocross tires were untouched for now.

On the mountain bike side, some of their best known tread patterns were reworked to improve performance. The Crossmark II gets a few redesigns to help with cornering and braking. The side knobs have been opened up by dramatically reducing the size of the round knob and spacing it out to every other section to help with cornering grip. The center section gets a ramped/stepped design instead of being full height all the way around. They’re also a bit wider, so there’s more of an end block on each ramp to bite in for better braking.


TPE15: IRC Tire 27.5″ mountain bike treads weigh in, new tubeless cyclocross tire

IRC Serac CX Sand tubeless ready cyclocross tire

At Interbike last year, IRC added the Sera CX Mud for wetter conditions. Now, they’re completing the spread with the new Serac CX Sand, a file tread version for much, much drier conditions. It’s also suitable for grassy courses (that aren’t wet) and gravel sections. It’s sized at 700×32 and weighs in at a claimed 375g.

Also introduced at Interbike last year were the 27.5″ versions of their mountain bike tires, and now we’ve got weights and a few other new tires and goodies to show you…


Nox Composites tease fully molded carbon road/cyclocross carbon rims

Nox Composites 36mm carbon fiber rims for road and cyclocross

Nox Composites is developing full carbon road rims that will come in both symmetric and asymmetric profiles. The design is mostly intended for cyclocross, but looked darn fine on the Pivot Vault set up with Schwalbe One slicks at their office. Both versions use a somewhat aero shape, with a 36mm depth that gets very flat along a broad section of the sidewall. Width is 20mm internal, about 28mm external. The asymmetric version will be used for disc brake wheel builds and rear wheel builds on rim brake wheels. Front rim brake rims will be symmetrical. What separates them from many other carbon rims on the market is the fully molded bead hooks… READ MORE ->

All-new Niner RLT 9 Steel takes adventure road bikes down a new path

Niner RLT Steel gravel road bike

The original alloy Niner RLT gravel road bike hit the road in fall 2013, and we reviewed it last summer after some great rides exploring our hometown’s back roads, trails and access roads.

Now, it’s getting a bit more adventurous by becoming one of few mass produced modern bikes to use steel. Seamless Reynolds 853 tubes to be exact, air hardened, heat treated and tested to mountain bike standards so it’ll handle any surface you steer it down. Other than very few minor differences in head tube length and standover on a the smallest and largest frame sizes, the geometry is exactly like the alloy RLT 9. The big difference is taking that proven geometry and adding the magical steel ride quality…


NAHBS 2015: Unbelievable Samurai Cycles segmented titanium disc brake road bike

Samurai Cycles

Like Cykelmageren, Groovy and Cherubim, Samurai brought out the kind of bike that challenges notions of what a bike could or should be. These builders make things that certainly aren’t for everyone, the looks rarely fall into standard notions of what bikes should be, and the details are often astounding.

Samurai’s titanium road bike checks all those marks by using Ebikan welding, which takes small, fan-shaped segments and welds them together to create curves. The entire frame is made of 3/2.5 titanium and every main component pressed into it is 6/4 ti. Cut past the break for a gallery of pure metal art…


TPE15: A-Class adds disc brake road, CX wheels; Alex Rims goes wide for fat, gravel


Alex Rims not only had one of the prettiest booths, they also had one of the widest varieties of rims for every application from road to mountain to enduro to downhill to cyclocross to gravel to fat bike. Even the new “plus” size category was well represented alongside a monster 36″ rim.

The complete wheels are sold under the A-Class brand and also had a smattering of new options, mainly for road, gravel and ‘cross. Roll on in for specs, pics and a complete overview…


TPE15: SEQlite machines lightweight steel, alloy and titanium cassettes for all

SEQlite lightweight chromoly and alloy mountain bike and road bike cassettes

Wide range cassettes and drivetrain systems were pretty big at Taipei, and SEQlite had a killer offering alongside standard and narrow range road cassettes that were impressively lightweight, heavily machined and made from an assortment of metals.

Above, the wide MTB Racing Cassette uses a one-piece chromoly cluster for most of the gears with a 7075 aluminum upper cluster of three gears to save a bit of weight. They’re available in both 10- and 11-speed versions, both of which fit on a standard Shimano 10-speed freehub body.
