I got this proflex today, I seen many mixed feelings on them. alot of people who ride newer bikes bash them but Ive wanted one some time and I couldnt pass this one up. I think of these bikes as a marvel. ive seen alot of old bikes but these ones are unique and have alot of neat  things about them. like the weird back brake.

Anywho What should I look for bewfore riding it? Should I break it down and regrease/check for wear?

Both suspention parts need fixing/replacing. Anyone know  any good options?

This is the bike

If you've always wanted one, just ride and enjoy!

I bought new elastomers for my 252 from here a few months ago: http://www.suspensionforkparts.net/
He has what you'll need to repair the shocks and, maybe just as important, the instructions on how to replace them.

t might be 20 years old, but it was ahead of it's time.

Hi Welcome to the group.
Great bike the 845 (I've just finished restoring mine )

Originally the front fork would have had elastomers similar to the rear and not a spring.
To be honest the spring makes for a rather harsh ride, convert it back to the elastomer
Send me a pm and I will send you a copy of the 1984 Proflex brochure which features the 845 in red.

The link above to the suspension fork guys is all you need, send the guys an email and tell them you have an 845 and a Girvin 1 Suspension fork, they will sort you out.

If you get stuck, drop me a line, or post on here, someone will have an answer.

Could I trouble you to measure the headtube badge, only need a width and a height at both high and low points at the top - cheers
Andy (with an 845, 855, 856, 656 in the hoard!)

I also STILL have my old 854, bought the frame brand spanking new (built with all the parts I wanted minus the girvin fork I couldnt afford at the time) and rebuilt the back shock a couple years back with the elastomers from that link posted above....I am quite happy with it and gave the bike new life again....and still riding it on the trails most of the time...
