I've just ordered a new bike that has a two piece frame with a shock absorber between the two sections.

I'm curious - do these type of frames hold up well? Just how are those two sections mounted to each other? I'm concerned that over time there will be more play. Is this a justified worry? These frames are new to me as I've always biked on a one piece frame (with the exception of my Brompton folding bike).

Just wondering. Thanks, Dave Horne

What you just bought was a FS mtb, depends on the make, they are usually very tough frames, well except for those Carbonfiber frames. When it comes in, post pics here. Also have a blast when riding it. I stand corrected.

Here's the bike. This is a Dutch brand, well known here, but probably not outside of Germany and Belgium.

No one in this hemisphere is going to be able to answer the ? (N&S America).
Looks like your highend Dutch bike about town, meant for dead flat terrain and most any weather. The shocks would be the parts to go first, and require maintenance on a fairly regular basis. Has a multispeed rear hub, internally
geared? Looks like fully enclosed drive system. Pivots on the frame would wear out very slowly. Steve

sch, this kind of construction is new to me and I was just wondering how this is on the bikes you are familiar with. Thanks for responding. DH

Bikes of this type are offered in North America by Vision, RANS, Giant as well as others. Not the fastest bikes but very well suited for around town and shopping. Built in racks, fenders and lighthing. The company building this bike has been looking for an outlet in the U.S. Some call them Hybred recumbents, but the name given to them is comfort bikes.

The shock is a coil over, most likly a very simple shock no real maintenance proplem. The piviots are most likly a nylon type and they will wear over time, and will need to be replaced. They could be bearings, and never need to be replaced. The chain is run though a chain tube to keep grease off your pants leg.

Thanks guys. I'll talk to my LBG re the construction of the joint connecting the two parts. If it is some sort of plastic, I will be disappointed.

It looked like a sort of metal pin or pop rivet. I'll have a closer look this week.
