YA !!!!!

This was a prototype stem and only seen on the Redline suspension bike in '75.  Simple design but difficult to adjust the stem bolt and clamp bolts.

Byron Friday tested this and reported them breaking so the stem was designed with the forward support and beefier clamps.

WOW, what a BIKE!!!  That is so great you have had it all this time, nice job.

When I was a kid I thought it looked so cool but it didn't ride well for me so I really didn'nt thrash it at all.  Squarebacks are so trick and has anyone seen a older serial number than 151?  So glad my Mom didn't sell this guy in one of her "garage sales"!!

Having the early RL stem is rad too.  Glad you all enjoy it as much as me for the last 33 years!!!

That bike is absolutley great!!

thank you for holding on to it for so long.

The design change was called the "Redline Slantline stem" I'll take a picture of mine soon and post it up

Very Very Nice Redline.

Thanks for the feedback and really glad I could build it up again to share with everyone on the site!  One of these days I'll get to my other RL's?

Damn SWEET collection , id love to get my paws on 1 of these

where is the serial number stamped at?

Squareback serial numbers are stamped on the bottom bracket underside

Thanks for the + feedback and adding more of my Redline collection soon

I believe KenC has a '74 with the stamp on the headtube as well. Or maybe he said there was no stamp? Can't remember...

This bike is surely a "Holy Grail" and another stellar build. JT your collection is too sick!

I'm very intrigued by the stem on this one... So basically the first Redline Stems came out in '75? I've always been a bit confused on the versions/timelines of early Redline stems and V-Bars.

Not to go too far off topic on this thread JT, but could you shed some light on the V-Bar and stem timeline? Do you know if the first V-Bars were Nickel and were they stamped? Sizes?

Also, I recently bought this bike from a member here and was wondering which version of Redline stem it was... I'm thinking it might be the 2nd version?

The pics aren't great, but you can sort of see it here:

Sorry I missed this post until now.




The first RL prototype stem 1975 - 1977


1977 RL Double clamp stem is released with the early prototype clamps


Late 1977 the new stamped clamps came out


1979 Dennis Dain replica Redline


As for the V bars, yes they were Nickel for the first ones and unstamped.  26" x 9" with a deep V bar bend which gave the bar a great look and a tad of flex compared to a straight crossbar per Linn Kastan.  As for the oval logo stamping I recall bars in '79 having them with the sticker also.  Production was moved overseas in '79 and not sure when the square letter stamp logo was exactly used after all the oval stamps were distributed?

Hope that helps?
