Silca Gives Those Pesky Valve Stem Extenders the Silent Treatment

silca valve extenders for presta valve bicycle tubes

Silca’s new Presta valve extenders’ clever use of elastomers and sealants put an end to the annoying rattle inside the rim hole and prevent air leaks.

On the outside, an elastomer ring is designed to sit snugly inside the rim’s valve hole and hold it firmly in place. That prevents it from rattling around until your nerves are shot, and it’s a good sight more attractive than electrical tape. You’ll need to measure the distance from valve hole exit to the inner rim bed and figure out the difference between that and you current tubes’ valve length to make sure it all lines up, but your sanity is worth it.

On the inside, they worked with a company that specializes in thread sealing to coat the inner threads so they seal tightly against the tube’s valve threads. Then, they added elastomeric gaskets at both ends of the interface to further plug the joint. The result is no air loss. Or at least no more than you’d get with just the regular tube.

But wait, there’s more…

WTB Trail Boss Speeds Up w/ Tighter Knobs, New Cross Boss Hits the CX Course


First mentioned at Taipei Bike Show alongside several other new and updated models, the MY2015 WTB Trail Boss is now shipping…and we’ve got pictures.

Designed with a very similar tread block shape to their Vigilante enduro tire, the Trail Boss gets ramped center knobs to be a faster rolling tire for rough XC but burly enough for all mountain pursuits. It’s only slightly less aggressive looking than the Vigilante, and only because the blocks are more tightly spaced. Side knobs are supported for hard cornering, and all blocks get a big, shallow sipe to help them conform to the little stuff. Rated for hardback through loam, dry to damp conditions.

Roll through for specs, size options and a close up of the tread pattern…and the Cross Boss…

2014 Van Dessel Whiskey Tango Foxtrot monster crosser gravel road bike

This year’s Van Dessel WTF (Whiskey Tango Foxtrot) do-it-all bike gets a new raw steel finish but is still the same super capable, extremely versatile bike everyone loves. A corrosion resistant treatment coats the bare looking tubes, though, so it’ll remain rideable year after year.

Founder Edwin Bull has been working on more than just new colors – he’s been growing the carbon fiber line and just sent over renderings for a whopping three new/updated models. One for road, one for cyclocross and one for the trails. Check out the sneak peek, plus detail shots of the WTF, below…

Famous for fun colors and happy customers, geekhouse has always produced some of our favorite custom bikes, but until recently, they had never produced a frame with Di2 internal routing.

This all changed earlier this year, when repeat customer Kerry Waldman asked Founder Marty Walsh to build his Mudville CX bike a little differently.

Head past the break to see the end result….


Prototype Kappius Components Disc Brake Road, Cyclocross Wheels Spotted


Spied aboard the team edition of the new Niner BSB 9 RDO cyclocross bike were prototype wheels from Kappius Components, put there by team rider and hub brand president Brady Kappius.

They are some pretty early test versions that helped them develop their own rims, and the final shape is going to be a good bit different. Brady says every contour and dimension were designed in house. They’re laced here to Kappius KH-1.5 hubs, which we saw at Sea Otter. We also saw their first production rims there, aimed at mountain bikers, with their take on bead hook design. That same design is mimicked on these rims, which they say are ready for both road and cyclocross.

2015 Cannondale CAAD10 Synapse Disc brake road bike

Cannondale’s 2015 road and cyclocross bike lineup commits to disc brakes, giving more road bike models the option and going all in for ‘cross. That’s right, all CAAD-X and SuperX cyclocross bikes are disc brake only, no more cantilever options. There’ll even be a SRAM CX1 build in the lineup!

The well regarded alloy CAAD10 models switched to internal routing for MY2014, and the new disc brake versions use it for both shift and brake runs. Cable ports are swappable for mechanical or electronic systems.
