having little trouble sourcing this bearing size. anybody else got a hope pro 3 sp am4 rear hub and ever done the bearings? were did you get them from? thanks
Any reason why you wouldn't just get Hope ones from a dealer, other than their [url= http://www.freeflowbikes.com/Full-Suspension/Wheels-Tyres/Hub-Spares/Hope/HOPE-BEARINGS/ ]£10 cost[/url]?
Simply bearings list in that size but only open or metal shields. They don't list rubber seals. I'd just stick with the hope ones myself.
Just had a look at the tech docs on the Hope web site. You'll notice that standard bearings are listed by code. They list non standard bearings by size. You need to get the Hope ones
It's a 6903-2RS, Hope's are stainless, but normal ones should be available from most bearing suppliers.
It's not 6903 - that's a 17x30x7
Strange, that's what came up on simply bearings site.
didnt know any hope dealers here other than crc,and they dont show on their website.. thanks for the link
IIRC A few of Hope's bearings are non-standard sizes - they have theirs custom made by INA. Quality bearings, though.
Ahah, got to the bottom of it -
6903 is 17x30x7
6903A is 17x32x8
But as above, you need the -2RS version which includes seals, which very few places seem to do. Looks like you need a decent local bearing supplier, or just get straight from Hope.
Noticed that, wonder would it be possible to put the old seals into the new bearings? I'll try a few local places on Monday to see as buying from free flow comes to 27 quid for the two
No - bearings without seals do not have the grooves for the seals
A black mark for hope not using easily available bearings. a part of their appeal is the availablity of spares.
Pro2 s were my first choice, but everytime a set came up here I was always to late. Bought a set of the am4 when they appeared out of haste not realising rotors are hard to get and same for rear bearings. As the ad said bearings were good I bought them, as soon as I fitted there was play.
