TPE15: Edco machines wide range mountain bike cassette & narrow range junior cassette, plus new wheels

EDCO narrow range junior road race cassette

Edco has been machining their Monoblock cassettes from a single piece of hardened chromoly steel for a while, but the designs have been limited to standard road gearing ranges. Now, two new options push the gear selection in either direction, from a very narrow range model to a two-piece wide range mountain bike cassette.

The new narrow range Monoblock cassettes for junior racers, shown above left, are because the youngsters can’t run anything smaller than a 14-tooth cog per UCI rules. So, they make a 14-25 and 14-27 cassette, both with 11 speeds, that gives young racers tighter gaps between gears without having to restrict derailleur movement to keep them off the smaller cogs. Expect them to be about $200 USD. Like the others, it’s machined out of solid chromoly steel. Also like the others, it’s an 11-speed unit that’ll fit on a 10-speed freehub body, making it easy to put an older set of wheels to good use. Weight is about 200g.

Shift past the break for more details, plus a look at prototype carbon rims and more…

The deeper groove section under the smaller cog allows enough interface on the freehub body that the cassette can overlap it a bit to make room for 11 gears on a standard 10-speed freehub body. More details on that here.

Prototype mountain bike cassette is also 11-speed, and also fits on a 10-speed freehub.

It’s actually a dual block design, which was necessary because the size of the largest cogs would require too much machining to carve it out of a single block of metal. Weight is about 262g for the 11-40, and they’re working on an 11-42 also.

Edco also makes their own hubs in house, and the Aptera sets the flanges very wide to improve bracing angle.

For now, they’ve purchased Reynolds carbon rims in raw form, without spoke holes, then run them through their own 7-axis milling machine to align the holes perfectly for their own hubs.

Above, the Aerosport series uses Reynolds’ AERO rims. If you’re wondering, that weight is about 70g heavier than Reynolds’ AERO 58 wheelset claimed weight, but the EDCO version uses more spokes.

The Albis Prosport wheel is coming for Eurobike and is the first time they’ve used their own molds to create the rim. It uses a woven carbon and HITG resin to keep heat in check on the brake track. It’ll run through the 7-axis milling machine to drill the brake holes also, and the rear gets their Aptera hub. This is as close as they’d let us get to it with the camera.

XTR 11sp cassettes also fit 10sp hubs, so I would say that Edco was doing something wrong if their 11sp cassette couldn’t do the same, unless they were trying to make an XD-style cassette with a 10T start cog.

and boutique junior cassettes? ok, sure. people gotta spend money someplace. little Johnny is gonna need a few for his quiver of Zipp wheels.

The junior cassettes would also be good for grown ups who want to run tight ratios but with reduced wear and better chain wrap

The Junior cassettes are also great if your kid is running hand me down 10s wheels with an 11s group.

Just what we need, another ridiculously expensive cassette.

@OG Mark, unfortunately racing at the U.S. National level requires the proper gear rollout without the blocking of gears. This cassette is a “real need” for those 9-18 year olds racing with an 11 speed shimano/sram groupset.

Legbacon…$200 for this is a steal compared to anything near its weight.

The junior gearing cassettes are one of very few 11 speed options.
It’s great that you can run them on 10 speed wheels, and that they won’t dig into the alloy freehubs as much.

Technically the rules don’t require a 14T small cog, just a certain amount of distance traveled per pedal stroke. You could run a 45T large ring with a 12T cog and use an off the shelf cassette with a more custom chainring setup.

Shimano now makes the cs6800 in 14-28.

If it shifts well, the junior option might be a good option. But honestly, most people would rather run a 10 speed cassette, with the 11 speed drive train than run an aftermarket cassette.

First hand knowledge dealing with EDCO. They need to lock in a US distributor already because their stuff is really great! I would easily recommend EDCO wheels and hubs over most all of their Euro counterparts.

Benedict, Reynolds is stocking the cassettes, nothing else. I was referring to wheels and hubs. EDCO has been entertaining the idea of a US distributor since Sapim sold the name to the current owners/designers in the Netherlands way back in 2000 or 01. They have a pricing and MOQ problem that doesn’t accommodate the North American market very well.

I’ve been running Edco hubs for years, laced to Tufo carbon rims. Excellent hubs!
