[Closed] Crank Brothers Joplin 4

yes x2

well. it's about to be replaced with new design with square tube and mechanical.. looks more reliable to me. is 4 much better than 3?

1"

yes, see.. the 3 goes wrong all the time. i know cos i have one. the UK distro is great but.. 3 returns to base? **** me.
so is the 4 any more reliable than the 3? probably not much, design is similar right.

£107.99 is about what i paid for my 3. you're going to get to know the distro guys real well, that's all i'm saying. on first name terms 🙂 so if you want a bling post and a long distance relationship, go for it. if you want one that always works, don't.

3 had a few internal tweaks supposedly to make it more reliable. Chief among which was dual brass keys to stop rotation instead of one, which means it takes a lot longer to get sloppy.

The design isn't the best, but they're pretty easy to work on and keep going by all accounts. I've got a whole load of spare parts in my shed that were donated to me, enough for almost 3 more full posts (just missing sleeves), and have been playing and there's not a lot to them. Pretty simple really, so easy to keep going yourself, just like all Maverick designed stuff...

cool, can you tell me how to repair an air leak around the lever please? 2pure are being strangely cagey about it, keeps happening, keeps going back. even out of warranty so all credit to 2pure, i'd buy another CB product if it was well made.

for some reason i'm almost tempted to buy another. stockholm syndrome?

evans don't specify the colour?

ah just noticed its 30.9, specialized size. removes any temptation or me.

Dunno how to help you there smiff.

To be fair, the one that's on my bike right now, I bought off a guy off this forum who's an engineer, and he'd rebuilt it to better than factory specs and it seems to work a dream. The others are all well abused spares in case I need any bits to rob.

Scottpat - I like my 4 but they do have a poor reputation. I like fixing things though so it doesnt bother me: its pretty simple to work on and fix. Does need regular checks and tlc to keep it sweet though.

smiff - I've put details on how to fix the air leak here:

You'll need to diy a tool.

awesome, thanks, that explains why they wouldn't just give me the o-rings. not a standard tool. might have a go 'cos it's 2 weeks turnaround (they're really busy atm hmmmm)

smiff - drop me an email (there's none in your profile).

Thanks very much all.
