All New Easton EC90XD Carbon Disc Cyclocross Fork & Disc Wheels Spotted on Diamondback RCX Pro!

2013 Diamondback RCX Pro Disc cyclocross bike with new Easton EC90XD caron disc cross fork and EA70 Disc wheels

Spied in plain sight was Diamondback’s 2013 RCX Pro Disc built up with an all new Easton EC90XD full carbon fiber disc brake fork. Clamped into the dropouts were some all new EA90XD disc cyclocross wheels, too!

Details weren’t flowing from Easton as these weren’t quite ready to be shown…seems a product manager at DB might have been a bit excited and jumped the gun. What we can tell is that the fork has a massive crown and legs with decent clearance. All curves are super smooth and post-mounts look sized for 140mm rotor…this one had a 160mm rotor with a spacer between the caliper and fork.

Read on for more pics, info and a look at the Diamondback bike they’re mounted to and more…

The EC90XD doesn’t have quite as much clearance as we’ve seen on some other forks, but without cantilever brakes to hold mud and grass, it shouldn’t be as much of an issue.

The hubs look like pared down versions of their Haven mountain bike disc hubs. Straight pull spokes laced two cross. 135mm rear spacing on this bike, meaning the rear hub is 135.

The rims are anodized (or painted) bead to bead, but it looks like there’s room for a brake track, so perhaps they pulled an existing rim?

One more look, now on to the bikes…

The RCX Pro Disc is virtually the same as their RCX Pro with the exception of the braking change. They’ve had the CCX ($900) and RCX ($1,300) for a couple years, new Pro models get more shapely seat tube that’s flared out at the bottom bracket to stiffen it up. All models are BB30 and have flattened seatstays. The top tube cover is placed where your hand usually grabs when shouldering the bike, keeping the cables from scratching the frame.

Steilacoom is a Native American tribe from their home area of Kent, Washington, as well as the name of a river there.

Flattened seatstays give it a bit of compliance over big bumps and dips.

Nice find! From the pictures, it looks like the fork is EC (carbon), and the rims are EA (aluminum).

So we’ll be seeing disc brake cross bikes in WalMart now? Nice Diamondback.

Nice wheels for a Wal-Mart bike.

would it kill them to add fender and rack mounts? it doesn’t seem like much extra work and you open up your sales of a model to a whole other group of potential buyers.

Wow. As much as I love my Easton fork, this new one looks like a mistake to me. Not only doesn’t it have fender mounts but also tire clearance below the crown is unacceptably low. Maybe it’s better than it looks but I don’t really think it would be very good.

Hungry4shht and ferno – can you point me to a Walmart where Diamondback is sold? Didn’t think so. When’s the last time you rode a Diamondback? Might be worth another look.

Diamondback appears to have put together a nice bike. Can’t wait to check it out.

NO, NO, NO. You will not see this fantastic bike in Walmart. You’ll have to go across the street to Dicks Sporting Goods if you want this gem!
