Industry launches new, larger threaded T47 bottom bracket standard – say goodbye to PressFit!


The first Engin Cycles frame with the T47 bottom bracket standard.

An idea has been floating around some of the smaller industry players for about a year now. Brands like White Industries, Chris King and Paragon Machine Works were all thinking that people liked threaded bottom brackets, but that frames and cranks had changed so much over the past decade, getting larger diameter tubes that didn’t go as well with the tiny English threaded BB. These ideas progressed in distinct conversations running their own courses until one company contacted another to make a bottom bracket, and then everything really fell into place to (hopefully) replace the pressfit bottom bracket.

The driving force was to take the advantages of a 30mm spindle and modern frames and combine them with the proven durability, quiet performance and lovability of the traditional threaded bottom bracket.

The result is a new standard called T47, for “Threaded 47”. It measures M47x1, meaning a 47mm outside-thread diameter with a 1mm thread pitch (25.4 tpi equivalent). That puts it very close to the 24 tpi (threads per inch) currently used on English threaded bottom brackets, so it’s essentially been proven on bicycles for many, many years. And that slightly finer thread pitch helps to manually hand tap and chase the threads, a handy feature for frame builders.


Review: Hutchinson Black Mamba CX tubeless-ready cyclocross tires rip through dry conditions

Hutchinson Mamba tubeless ready cyclocross tire review

Hutchinson has been a first mover in tubeless-ready tires for both road and cyclocross, and that experience shows through. On both the pavement and grass, we’ve seen them seat easily, sometimes even on rims that have been challenging with other tires.

We’re testing several of their cyclocross tires this season, the fastest of which is the barely-there treaded Mamba. It’s a dry conditions tire that’s lightweight, supple and very quick. Mostly, we really like it, putting two sets under two riders in two different locations. But, like everything, there are tradeoffs for making something so specific…


Review: Thule ProRide upright roof mounted bike carrier – Updated


With a wide range of bikes that come in and out of our European HQ to test, it can sometime be a bit tricky to keep track of how to get them to and from races and to destination trails. While we often rely on roof mounted trays for their stability and for not adding to the overall footprint of the car, now that so many bikes use different axle standards it has been a bit more difficult to deal with. Most fork-mount bike racks offer some versatility in the thru-axle department, but often with the compromise of losing the ability to lock the bike or just being fixed to one axle size. Our solution for the last year has been a ProRide 951 carrier from Thule. We’ve used it to head into the Alps on several occasions, as well as to get to all of our regional cross races. Have a closer look after the break to see how it has fared in our travels…


CX Review: SKS Airchecker Digital Pressure Gauge – Updated


With cyclocross season in full swing, the weather in Europe has been cycling back-and-forth, all over the place. One race weekend has been be warm and sunny, then the next was frosty and gray. That’s makes tire selection and tire pressure choices even more important as we try to squeeze out the last bit of grip from a wide range of tubulars and tubeless tires that we have on test. We already raced on everything from dry hardpack and grass, to slow and slick muds, to wet and frost covered grasses. To get tire testing right, we need accurate and repeatable tire pressure measurement, and for the last couple of seasons we have begun to rely on the Airchecker, a small handheld digital pressure gauge from SKS.

Tempest 1

With all of the carbon and hydro-formed aluminum bikes blending into each other, seeing a vintage steel racing bike’s slim lines and soulful stance reverberates in the hearts of many. Whether a new or seasoned rider, it’s hard to mistake something that is as timeless as it is classic and Bombtrack wants to take us back with the Tempest.

A Week in Review: Turner Crosses it Up, Step Back in Time with Orbea…. and What is Jens Saying now?

As the weather shifts, the wind chills, and the leaves fall, we enter into the worst day of the year for some, as others excitedly scramble trying to remember where they…. or someone else put their light charger. In the mean time, we had everything from awesome to odd this week. Bike locks are simply not what they used to be and TiGr, Abus and Hiplock brought us their own take. Sufferfest and BKool create new ways to make emerging from the depths of your pain-cave harder than ever, and a new dropper….. err, stem from 3SFtech.

So sneak a handful of your kid’s trick-or-treat candy, (but don’t be these parents), and look to see what you missed this week….


Review: Kontact Saddle puts you in the power seat for cyclocross & XC racing

Kontact Saddles long term review and actual weight

Kontact Saddles debuted in early 2014 with a uniquely shaped saddle promising to fit your sit bones better and provide unencumbered pedaling. What I found is it does all this and positions the pelvis in a forward rotated position for a more powerful pedal stroke.

Add to that a durable design and materials, a competitive weight and price and this could be the perfect saddle for intense efforts like cyclocross and XC racing. For longer rides that that aren’t full throttle, well, maybe…


ITM adds light, affordable Alutech A and Ergal aluminum cockpits for road and trail – Updated with Pricing


ITM added some more affordable aluminum components to their line-up for 2016. The Alutech A line is a premium alloy road cockpit group with low-key graphics that all share a 7075 aluminum construction to provide a balance of  comfort, safety, and value. For the mountain bike, the Ergal bar and stem slot in at the top of their aluminum offerings as well. They deliver weights near their carbon bars and lower than any of their trail stems, at a lower price point. Jump past the fold for a closer look, some tech details, and pricing
