Bodge to fit a new Hope "press fit" BB
I bought a shiny new Hope press fit BB, hoping to do my usual garage based bodging to get it to fit.
I’d planned to use my homemade headset press and then get a nut or bolt of some description to fit it and screw the other cup in. The Hope tool is 40 odd quid and I’d likely only use it once. I know I could take it to my LBS but I like a bit of a spannering bodge* and I’m not in a massive hurry.
The space across the inner flats on the BB is 25mm. I’d planned to use a bolt but the closest is an M16 @24mm.
Anyone any ideas? I haven’t had much luck looking for a 25mm Allen key :).

There’s an interesting bit of trivia. I’ve a rubber strap for tightening up plumbing fixings that might grip the lockring tool. Bodge coming together nicely :).
I’ll admit I’m relying on the BB tightening up easily. if it’s a bit of an effort I might just get the tool from Winstanleys. Much cheaper than I’ve seen it elsewhere.
Out of interest for anyone that’s got the tool, does it make pressing the bearings in/out easier? I’m assuming the removal is “old handlebar to hammer them out”.Posted 3 years agoRusty MacSubscriber
I bought the tool for 2 reasons, 1 was that none of my lbs had one at the time and all were going to charge full rrp for the BB as a special order item and then £25 for fitting. It worked out cheaper to buy the BB and tool online and do it my self. 2 was with the thought it would be usefull for replacing bearings How ever I am not to sure how you would go about removing the current ones before pressing in new ones.
Think it’d have to be a drift of some kind 9mm bar or such like to get through the centre tube at a reasonable angle to get at the bearings. Don’t know if you could undo the centre tube to push the bearings out or not.Posted 3 years agolerkSubscriber
Mt ‘tool’ consists of an M16 bolt with a layer or two of insulation tape wrapped around a trimmed nut to give a square edge with a second locking nut behind it.
Also a 10 or 12mm form A washer and then a large repair washer worked a treat on my
length of threaded barhugely expensive headset press to get the cups in… the form A washer sits inside the housing lovely and keeps it all lined up.
I’d send you a bolt but the postage would be more than you’d get a bolt for locally… (try a towing place ;))Posted 3 years agoalanfMember
Motorcycle front wheels often use a short length of hex bar as a removal tool. Not sure on sizes but you could have a look at something similar.Posted 3 years ago
