Hagen Green’s Clean Machine

Alfine 11 drivetrain -- dig the snazzy red Gates belt!

Hagen's clean, clean build. Note how the cables are barely visible.

Our silver-plated, solid brass headbadge and TRO Orange paint.

We heard from a very happy Speedhound owner who sent us a link to his blogpost about his experience planning, building and riding his Only One. It’s definitely worth a read if you have any interest in putting together your own custom ride.  Hagen gives us an in-depth view of how he planned his bike and how pleased he is with the results. He had a few bugs to work through with his Alfine hub at first, but flushing and changing the lubricant and fine-tuning his Versa shifter set things right.  We love his impressions of the ride qualities of the Only One and how it compares with his other bikes.  Thanks, man!

A Sporty Alfine 11 Belt Build

Alfine 11 internal gear hub, disc brakes, belt drive -- this one's got it all.

Talented Speedhound customer, F.D., assembled this sporty belt-drive Only One with a Shimano Alfine 11 rear hub and Versa drop bar shifters.  Avid SL Road disc-brakes provide reassuring stopping power and the dark brown Brooks saddle and bar tape are an elegant contrast to the Ice Cream paint.

 

F.D. wrote to us: “Just wanted to let you know that I finished building out my Speedhound and took it for a test spin a couple of days ago…and came home grinning. Still got a few things I’m adjusting, but I’m loving this. I can’t get over how silent the bike is while riding. Still getting used to being able to shift at a stop, though. Thanks for all of your help from the initial purchasing decisions and for answering my questions along the way. This has been a great experience for me. It took me a little longer to finish than I had hoped, but I’m loving the final result.”

Take a look here for photos documenting the build process.  We think this Speedhound shows just how performance-oriented an internal gear hub and belt drive can be.

These Versa shifters are designed to work with the Alfine 11 speed internal gear hub. Drop bars give a rider a choice of hand positions and allow a low, athletic position on the bike.

At the customer's request, we painted the slider dropout to match the frame. Note the adjusting screw at the front of the dropout. This allows precise tensioning of the belt.

 

Happy Rider

Forward-thinking Speedhound rider Stephen Y. built out his 61 cm ONLY ONE with the disc brake option, Gates CenterTrack belt drive and a NuVinci hub.  With its New Black paint and all black components, it’s very stealthy, especially with that smooth and quiet belt drive.  Stephen wrote “Went out for the maiden voyage yesterday.  Wow, this drivetrain is smooth.”

The  55 tooth front and 24 tooth rear sprockets give the NuVinci hub a very usable range of ratios for the road.  Low gear is 30.7 gear inches (equivalent to a 39 X 34) with a top gear of 110.5 gear inches (equivalent to a 53 X 13).  The hub is a continuously variable transmission (CVT), so it provides an infinite number of ratios between low and high.  “Bottom line – this whole belt drive, IGH, and disc brake setup is fantastic” Stephen told us in an e-mail.

On the flip side, an Avid mechanical disc brake provides super stopping power in the wet. The caliper always stays aligned with the rotor, regardless of belt or chain length.

 

 

 

 

 

 

 

 

 

 

 

The brake caliper mount, fork tip and fender/rack eyelets are water-jet cut from a single piece of high-strength steel alloy.

Sometimes we get writer’s block at Speedhound HQ, so it’s great to have a Speedhound rider help us out.  “I could not be happier with the new bike, and I would heartily recommend SpeedHound Bikes to anyone who asks. I am equally impressed with the quality of your frame and your post sale support.  Count me as a fan.”

Thanks for the shout out and pix, Stephen!

Disc Brake Details

The Speedhound Dropout System now includes a disc brake option!  We’ve tested and refined our slider-style dropout and now have the production version ready to go.

Installing the dropout is easy.  If you’re using belt drive, you slip the belt through the slot in the frame receiver, so that it’s inside the rear triangle.

Then a backing plate bolts into the receiver with standard chainring bolts, just like the other types of dropouts in the Speedhound Dropout System.

The slider backing plate closes the slot in the receiver.

The last step is to attach the dropout and insert the tension adjusting screw.  The dropout has about a 16 mm range of adjustment, so it’s easy to dial in the proper belt or chain tension.

The screw at the nose of the dropout lets you adjust belt or chain tension. Tighten the two fixing bolts, and you're ready to roll.

At the left side, there’s a dropout with standard ISO mounting tabs for a disc brake caliper.  The beauty of this system is that the brake caliper and axle move together, so that the caliper is in constant alignment with the disc.  To increase belt or chain tension, the dropouts slide back in the frame.  There’s no need to separately adjust the caliper when moving the axle.

An Avid mechanical caliper and 140 mm disc rotor stop this Speedhound fast. That's a Nuvinci CVT hub with Gates CenterTrack belt.

The ONLY ONE frameset with the SDS slider dropouts and disc-compatible fork sell for $1,550.

Cooper approves.

Disc Brake Option!

You’ve been asking for it and now we have it — the disc brake option for the Speedhound ONLY ONE!  Now you can have the reassuring performance of front and rear disc brakes with the versatility that makes the ONLY ONE unique.  Our new slider dropout works with any rear disc hub with 135 mm axle spacing, including Shimano, Rolhoff and NuVinci internal gear hubs.  Of course you can also use derailleur systems and single-speed MTB hubs as well.  Because it’s part of the Speedhound Dropout System, the slider dropout also accommodates belt drive.  A disc-compatible fork with our fancy double plate crown rounds out this new option.

The disc brake option has ISO tabs and is compatible with a wide varitety of calipers.  Adjusters enable you to dial in precise chain or belt tension.

An Avid mechanical disc brake and 140 mm rotor scrubs off speed in a hurry. The fender stay attaches to a mounting point ahead of the caliper. This design also allows the use of a variety of racks.

The Speedhound ONLY ONE frameset for disc brakes is offered at the introductory price of $1,450, including free shipping to the continental U.S.  It will be available late November.
