Press fit bb? reccomendations?
Well,Posted 4 years ago
Someone posted on here a week or so ago and took an Anthem X29 into 18 bikes and was told it wouldn’t fit.
They had to ring up Hope to confirm it.
Apparently there is some ridge inside the shell so it will not line up.
If anyone can confirm this I would be grateful.
It would be my first choice.

Forgot about Chris King.Bet its pricy though.
I rang Hope up and they confirmed there’s a problem with the Anthem X29 and there pressfit bb.Trying to work round it so we should know in due course.No availability of that new XTR as yet so have ordered a Enduro pressfit bb from BETD so I will see how that fairs.Seems rather cheap at 30 quid but bearings are replaceable (bought some spare ones).Seems replaceable bearings are the order of the day which mite mean they wear out quickly? We shall see.At least I don’t have to buy the cups.
Just to say that my lbs (a Hope premier dealer) have tried fitting a UN71-41 equivalent Hope pressfit bb into my 2012 Trance frame – it definitely doesn’t fit. 🙁
The reason is that the bb shell has a smaller I/D (approx. 36.5mm) in the central part between where the cups are pressed in than the O/D (approx. 37.5mm) of the extended part of the non-driveside cup of the Hope bb. I’m guessing that the same applies to the Anthem frame as well.
The extended part of the non-driveside cup is the bit that the head of the threaded inner sleeve mates with (it passes through the non-driveside and threads into the driveside cup). Apparently Hope designed it this way so that they could use one inner sleeve design for MTB (89.5-92mm) and road (86mm) pressfit bb shell widths.
I’m going for the Rotor version instead, although it doesn’t have an inner sleeve.Posted 4 years ago
