does anybody know which Angleset I would need to get?
as another option betd do an aftermarket linkage but how does that affect the seat tube angle as it’s already too slack!
I don’t have the answer to your question but is it the silver and green one with white revelations, or the blue and green one with the Pikes - might make a difference.
Blue green pikes
I think that’s about 68 degrees ish as standard maybe?
I have a bike where the manufacturer offered a new linkage to give the bike longer travel (also a 4 bar suspension system) and that slackens the head angle / lowers the B.B. / slackens the Seat angle.
Interesting that the betd one just claims to slacken the head angle / keep the travel the same / keep the B.B. the same height. They don’t mention the seat tube angle.
I’m already running offset bushes and find the seat angle a bit slack I.e on technical climbs I find it wanting to loop out. I wouldn’t like to run the seat any further forward either
I can’t quite get my head round what the betd would do but I suspect it would have to slacken the seat tube further
I guess you could ring them / email them and ask?
If it does then maybe you’re just at the limit of the frame. I had the silver one before yours and decided initially to change the frame, but in the end I sold it whole and bought a new bike entirely.
But yours has better kit on it like the Pikes / GX - something like an Airdrop Edit would fit most of your parts on and you could put a longer airshaft in your Pikes to match the longer travel probably.
There's a betd linkage on ebay (not mine ) . Search Boardman and you'll find it .
AirDrop edit looks almost perfect but too heavy
yeah found the linkage on eBay but don’t want to gamble unless I’m sure
I had the previous boardman pro fs and test rode an Airdrop Edit before going for a Bird Aeris. I can’t say I noticed the Edit was that much heavier when I rode it, and the same for the Aeris. Obviously they’re both a bit heavier - they’re much stiffer / more solid frames, built to take some tough riding.
That said, the Boardman kit is fairly light attached to the frame - surely the actual frame can’t be that much heavier? Most of the builds are quite robust with Yari / Lyrik / enduro wheels etc.
Are you asking about the angleset to save removing the current headset and measuring up?
I recently went through the same process with an old Ariel frame, and while it was very confusing to start out with I found some good links and info which made specifying the headset pretty simple.
In case it helps (or helps a future wisdom-seeker), this Park link de-mystifies headset standards:
https://www.parktool.com/blog/repair-help/standardized-headset-identification-system
So you just need to measure the inner diameter of the head tube top and bottom, and measure the head tube length. Then combine this with the steerer dimensions of the fork you're running, compare and contrast with the Park website, and you have your headset specification.
This gives you the information to select a headset from Superstar or Works or whoever. I understand that you usually have one cup external to allow for clearance of the steerer through the head tube, so bear that in mind when selecting.
that's helpful Tom thanks.
i believe though most headsets are press fit and are a bugger to get out though?
The cups are press fit, aye.
How much of a bugger to get out they are depends on the frame and the cups I think. You can get special tools for removing them, or drift them out with a bit of wood and a big hammer.
There is of course potential for screwing up the frame in the process, so caveat emptor, but so long as you're not totally cack handed you'll probably be ok. Plenty of YouTube videos cover the procedure.
Note that installing the slackset requires a bit more finesse in that you have to align the cups in the frame so that the steerer holes line up correctly.
Just thought, if your frame is reasonable recent the manufacturer might be able to tell you the dimensions you need without removing your existing headset. My Ariel was old enough that such information wasn't easily available!
The Boardman website lists grid as the standard headset - does that help:
FSA Orbit C-40 ACB/Industrial 1-1/8" to 1-1/2" Tapered - Integrated
Hi cookie did you get sorted with the angleset? If so can you let me know which size u got please
Correct me if I've missed read the park web page.
As I read it, while fitting an angleset will slacken the head tube. In this case because you will have to use an external bottom cup which will raise the stack height effectively slackening the seat tube too.
