[Closed] Blackspire Stinger - setup tips?

its a dual ring device, designed to work with a front mech.

have you got anything keeping the chain on at the top?

is it? damn. Bought it to replace a redundant front mech. doh!

There's your problem, 32 tooth ring.

The Stinger is falling about laughing at such a girly gearing and is knocking your chain off in the process.

😉

Honestly, try a slightly bigger ring, Blackspire Stingers (in my experience) work best with a 36ish toothed ring on the front (its what I run with mine).

Get a [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=21874 ]DMR chain cage[/url] and you'll be laughing. Or just an old front mech with the limit screws bodged/cable reversed.

ok, but that would mean a new bash - (34 max at the mo) - a new ring etc - boohoo! don't have the cash at the moment.

Would removing a couple of chain links improve matters?

MrA. I don't want a front mech - it'll ruin the baggy jean vibe! 8)

Remove and replace with e13 srs or lg1.
Fixed.

I presumed you had done that already!

If you're referring to the problem of your kecks catching on the front mech/top of the guide, I don't find it an issue and I regularly ride in trousers that would put Kriss Kross to shame.

The chain is as short as I would normally run it for a single ring - i.e. rear mech arm at about 4 o'clock when in the largest sprocket. Should I go shorter?

Adam@Homers - Bit of a price difference between a Blackspire Stinger and an E13 SRS or LG1. Bit of a difference in the actual make-up of them as chain devices, what with the Stinger being a simple (and relatively light) roller and the E13/LG1 being a comparatively heavy and more complex device.

Not really helpful advice on the whole.

Do you reckon it would be possible (and cheaper) to fabricate a replica of this on the cheap using diy tools and a sheet of alu? It seems to be essentially a circle with 8 holes.

"Replaces the granny ring to help retain the chain on mid-ring/Bashring setups. Becomes an affordable alternative to a chainguide when paired up with the Blackspire Stinger"

and yes I'm skint - cheap solutions required!

A mate made a BMX grind disc out of one of those white plastic chopping boards. It was a bit rubbish to be honest...

its a dual ring chain device so I would expect the chain to jump off to be honest.

You could try putting on a standard blackspire roller for a single ring chain device and seeing if that works, as I don't see why it wouldn't.

cheers rich

Mr.A; chopping board bash - sounds proper 'core - 🙂

I would agree that there is a substantial price difference, and I was being somewhat irreverent, BUT you cant accuse an LG1 of being heavy 😉
