I'm looking for some advice on a power trax frame I bought recently. Firstly, Is the steerer tube 1" or 1 1/8"? Threaded or not?
It's been a while since I did any off road cycling and want to get restarted.

Hi and :welcome: @daviej

I'm afraid I don't know this model. A quick search suggests it's a rigid frame MTB from the mid 90s and from the photos I've found it looks like they had 1" threadless headsets. However, yours might not be the same era or spec.

As it's just the frame you've bought, can you measure the internal diameter of the head tube? If it's to take cups for a 1" steerer it'll be 30mm approx. If it's 1 1/8" it'll be just under 34mm (according to my Park Tools book).

Asking the question in the "Mechanics, Bike Fitting and Repairs" section will get a better response.:okay:
