Hope Big Un Hub Converters

[mikeeeeb]

i mean mounting yoke! no eggs were use to repair the shock! BETD made a replacement yoke wich was spot on. found out that BETD stock or can remake a few spares for GT full sus bikes of that era

Hey Tony i got the adapters you sent but sadly they are wrong ones. do you want me to send them back to you? i think they are for a Hope Bulb. thanks anyway!

Ah crap how comes there different swear they were the same ?

 

[mikeeeeb]

its the second time i been sent the adapters for a Bulb! the BigUn adapters push into & are located by the bearing rather than being held by an external circlip. the bearings in A BigUn have a bigger internal diameter than 20mm & the adapters push into them like the 15mm adapters for a modern Pro 2 EVO.

I may have a set at my mums (in black too) let me have a look over the weekend

 

[mikeeeeb]

that wuld be great mate! im not fussed about colour at this point but the hub is black so that wuld be perfect.

It's a black hub for sure, is there any difference between the mk1 & mk2? I have suspicions it's a 1st gen one

 

[mikeeeeb]

good question! i can tell them apart visually but technically my knowledge is a bit vague. i think the bearings used are different sizes. they have very different part numbers. culd the first gen BigUn be converted to 20mm? hence they produced a gen2?

 

[mikeeeeb]

i think iv roughly worked out the difference between gen1 & 2 BigUn front. the gen1 hub required a bearing change to work with 20mm axle & the gen2 was desighned to switch between 20mm & QR from the box with no bearing change. no idea if this affected the 20mm adapter collar design though! if anyone on retrobike knows better please let me know!
