I have recently received a Raleigh Grand Prix 10-speed bike. I would like to know what the minimum height (my height) requirement is for this bike ?
How do I know if the bike is too big for me ? I am around 5'5" tall.
And how do I lower the saddle stem ?
Okay....now that I am a pest I hope that someone can help me....please !!!!

Can you stand over it, with both feet flat on the ground, or does it get fresh if you try that?

Can you send out pics of your bike? I also have a Super Grand Prix that my wife (girlfriend then!) gave to me over 30 years ago before we married. I haven't been doing much riding due to knee and hip surgeries (too many to count !). I stand about 5' 6" and the bar does hit just below my "danger zone". Looking forward to hearing from you.

Welcome aboard!! Like they said, straddle the bars with at least 1-2 inch clearance.
Adjust the seat up or down by loosening the seat steam clamp bolt/quick release lever
where steam goes into the bike frame.

Height on the bar.

When I am standing stradding the bar with my feet flat on the ground the bar is right at the crotch area but not pressing.

As far as the seat steam clamp bolt goes I have no idea how that works. I am able to take the seat on and off but the silver tube that the seat is fastened to is the one that goes into the tube of the frame. I know that I sound like such a novice.

If you had to make an emergency stop, are you comfortable with that level of intimacy? Most cyclists prefer a bit more margin for error.

Where the seat post enters the frame, there will either be a nut, allen bolt, or quick release lever. Loosening that will allow you to raise and lower the seat.

I really would prefer more of a margin of error. It is really close. I thought that if I could lower the seat stem then I would at least feel more comfortable if I had to come off the seat in a hurry. I would hate to have the bike just sit around because it is really in very nice shape. Was kept in a gargage by a cyclist up on hooks and rides really well. I was originally looking for an older model Raleigh Record and not a Grand Prix.

There seems to be a bolt. It is silver on both sides of the bolt.

Lowering your seat isn't going to make the frame any lower. No matter how nice the bike is, if it doesn't fit, it doesn't fit. I guess you must acquit.

 

[barbb]

You are so right. How does an Allen bolt adjust? This is the first time I remember seeing one. When I had the Record it was sized directly to me so I did not have the issues that I am having now with the one that I "inherited".

Righty tighty, lefty loosey.

The heads of this bolt are flat with an identation into the bolt. Is the right as you are facing the handlebars from behind the seat or is it right as you are facing the back tire from in front of the seat ?
