Angle sets on older bikes....

[Mikey08]

Theres a bloke on Pinkbike making - 1.5 angle sets for 1/8" straight headtubes.

Also Works Components make one with - 1 degree.

Has anyone any experience of fitting these to older bikes and their effects on the handling?

My 2000 Kona Kula was originally designed around a 80mm travel fork and old school geometry. However I've been running it with a 100m travel fork and even tried it with the fork set to 120MM (2012 SID xx). At 100mm it slackens the head angle quite nicely even more so at 120mm, but on the longer setting the BB feels high. As I understand it running a slack set brings the bb a little closer to the ground. So I want to try one and run the fork at 120mm with quite lot of sag, around 30mm, with volume spacer's to compensate for the softer setup.

Anyone done anything like this or have any thoughts on the idea?

Cheers!

Re:

Not exactly the info you asked for, my Orange Sub 3 should run 80 to 100 travel forks but I'm taking the pi55 with 120mm no probs. I then slackened the angle by a further 1 degree by replacing the shock bushings with an off set pair.
The effect was to change Oranges already excellent XC bike into an even better (for me) trail bike.
I can't say that I'm getting any more peddle strikes since the two upgrades either.
I was so impressed with the ride that I've since bought a newer (2009) Orange Five from here and couldn't pic a favourite between the two.
Thanks for the info BTW I will be looking into it further. Once you've tried slack there's no going back.

haha!

I did some rough measurements and calculated that with a - 1.5 angle set and my 'longer than intended' forks id have a HTA of around 67.5 degrees. Which is pretty modern as most bikes these days are around 68 to 65 degrees as far as I can tell. Id also get a longer wheelbase and a slightly lower BB.

The major issues with over forking a older hardtail is you get a high BB and even slacker seat angle so a angle set compensates for this a little. In theory...

Just bumping this old thread as Im thinking about using one again on my new project.

The problem Im mainly worried about is the effect of a longer than intended fork slackening the seat angle too much. Seems like a pretty big compromise that could out weigh any steering benefit.

Also another concern is running a longer than intended fork at a slacker head angle could over stress the frame?

Any thoughts or experiences out there that youd care to share?

Cheers

I revived an old 26" hardtail ( MY2000). Wider rims to fit bigger tires and went from 100mm to 120mm fork travel. I believe the difference in axle to crown was about 45mm! Also installed a 1.5 degree angleset. I ride this bike on trails that are very tight, twisty, and flat. I think of it as a large bmx bike. Turns great and is a blast to ride. That being said I have never done any serious climbing on it so not sure how the seat tube angle would work.

Thanks Motomax.

My previous bike was a 2000 Kona which I believe was intended for 80mm forks. I ran it with 120mm forks and it was okay on flats and great on downs but when climbing I did notice the slack seat angle. Running a shorter stem compounded this. I ended up with a 60mm stem but was considering a 70/75mm.

Im probably going to try one. If things are too slack ill drop some travel spacers in the fork to bring the front end down a bit.

If you are buying the angle set from RG Bike Components in Italy, rest assured it will be the absolute highest quality. I was amazed when I opened the package.
