Product Details

All CLEMS, L or H, are our least expensive bikes because there's less labor in them--because most joints are Tig-welded not lugged. Tig-welding is super strong, it just takes about 1/7th the time as a brazed, lugged joint.

But they aren't lug-free! There's a seat lug, two lug-like head tube reinforcing rings, and one of our ultra-duper fork crowns. It's our model RC-05, a wide, flat-shouldered crown that's also used on our Hunqapillar and allows tires up to a 2.4 easily.

As a trail bike, commuter, shopper, all-around ruffabout bike, a CLEM is as pure and perfect as you’ll find anywhere. I/Grant think of it as a mountain bike–and the frame does pass the mountain bike EN test, the toughest in the world, so it’s not going to break on you. But in the 2017 real world bicycle market, "mountain bike" has come to mean 'barely a bicycle anymore, mostly a motocross bike, with motocross bike aesthetics.'

CLEM is no less a mountain bike for its lack of suspension. It doesn't encourage you to ride like beyond your limits, though. With no mechanical suspension, you ride rutted trails with your joints relaxed and absorb shocks unthinkingly-automatically, the same way you’d do it if you jumped to the floor from the top of a ladder.

An unsuspended/natural style mountain bike rules out showing-off and stupid riding. It means you go slower, which means you might not keep up with your full-gizmo’d comrades. You travel over the ground, you don’t go at it with the latest land-conquering weaponry developed for the modern mountain biker.

The CLEM will be around and in use in 60 years and will still be great bikes then. There's nothing weird about it, it will always be easy to service, because nothing is hidden in blackboxes and there's nothing electronic. It's a bike that will outlive all trends and keep on going. Un-obsoletable!

(We also have made  64cn CLEM-L--a mixte-style big bike. It's a smart bike for any rider over 6-feet tall, but most riders think tall mixtes are only for giant women, so we've made only 12 and may not do more than that. It's not a mistake bike in any sense; it's just a smart bike that nobody's asking for.)
