Off-set bushings on a Five – anyone done it?
I use to run some on my five. unless they have changed the mounting hardware I’d get two, one will make sod all difference. What’s the offset on the ones you are looking at? I made mine and from memory I had 1.5mm, so that’s 3mm total. The leverage ratio on a five is around 2.7 to 1 so the rear wheel ended up sitting 8.1mm higher up (2.7 x 3). This equates to about 5mm bb drop and less than half a degree on the head angle. There’s no way in the world to achieve 1.5-2 degree change in head angle with bushes!Posted 4 years ago
Bedfo – cheers for that, useful stuff and I know you’ll know your stuff. I’ll make it a pair then. The Five’s pretty much mint as it is – I’m only thinking about a temporary mod for an imminent Lakes trip. By the way, if you fancy meeting us up there for a ride (Sep 1st for 5 nights, me, both Marks and a couple of others) just mail me.Posted 4 years ago
I’ve been thinking about this recently. I’ve got an old straight top tube five and would like ot try and slacken it off a bit. Been looking at the on one slackset, or works components, but would it be better to get off set bushings as well or one or the other? And what would it actually do to the bike? New frame might be in order at some point but not till next summer probably……..Posted 4 years ago

I did this with a 2006 frame. I used a 1 degree works components headset (the biggest change you can get with that old 1 1/8 headtube)and a set of burgtec bushings.
The headset decreases the head angle by 1 degree and increases the seat angle by 1 degree
The bushings also reduce the head angle by 1 degree, but also reduce the seat angle by 1 degree.
So, using them both together knocks 2 degrees off the head angle while keeping the seat angle the same.
Both reduce BB height though, so I combined this with a 150mm fork (20mm longer than the 130mm fork that was originally specc’ed on the bike), which also knocks a degree off the head and set angles, but raises the bottom bracket. Overall I thought it worked pretty well, but not well enough to cover up for the fact that the frame was too small for me.Posted 4 years ago
I’m running pikes generally at 140mm but maybe pre-empting next years frame change and looking for some u-turn lyriks I can set at 150mm would be an idea. To be fair the bike generally gets used for going down hills.
Might give it a go and see how it rides. Cheers roverpig.Posted 4 years ago
