Headset question

energetik

Pardon me if this has been asked before, or is a totally idiotic question.

I just got a Mongoose Rockadile for free, and I want to upgrade a few things. This thing has a threaded headset, and I would like to convert that to a threadless set so I can experiment with a few lower end front shock forks before I take the plunge on a better bike. Is that even possible? I know this bike blows, but I'm just getting into it, and this seems like the perfect way to do it. I mean it was free. If I screw it up its not going to cost me anything.

Basically I have a line on some lower end parts that I want to try out. The fork I have in mind is a Rockshox J1. I have no problem getting a stem, and threadless headset to go with it. Assuming the diameters are the same can this be done safely? This bike currently has no front shocks of any type as it was made before that trickled down to the low(er)(est) end and that will be painful. Thanks as always.

Yes. You just have to decide how much you want to spend for the threadless headset.

I replaced the threaded headset & fork on an old Trek hardtail (early 90s vintage) with an FSA 1 1/8" threadless headset & suspension fork, etc.

The odds are VERY HIGH that your Mongoose frame also uses a 1 1/8" headset.

You will need a 1 1/8 headset to fit your frame. Be aware that as the frame is old it will probably not be adjusted for suspension. therefore by adding the fork you will be lifting the front end up. depending on the length of the fork this can affect the steering of the bike and potentially put stresses on the frame that it was not designed for. worst case scenario is frame failure. it is unlikely but you should be aware of the risk. What length is the fork?
