Is there any point in filing off the burrs on the current chainring?

unless you scour some of the retro forums, or a careful e-bay search I don't think you will find what you are looking for on-line

it may well be worth taking to the current granny with a file, especially if its steel

Derryn Hinch · *by **Derryn Hinch** on Sun 4/Mar/12 9:32pm*

'tis steel so I'll try that. Thanks for the help

All the 22t chainrings can find online are 64mm BCD.

It is for an old (1998) Sugino MTB crank.

This kind of Sugino 4-bolt 58mm BCD crank? :sly:

Here is a genuine 4-bolt 104/58mm BCD, Surly used one too.

SJS has a 4-bolt 58mm Sugino ring, or a whole steel set for not much more.
http://www.sjscycles.co.uk/obsolete-obs ... pt514_pg1/

58mm has traditionally been a 5-bolt pattern, Sugino hide one bolt behind the arm.
Also RaceFace made 94/58mm 5-bolt rings, and Middleburn, TA, Coda (rebranded).

There have been steel 22T 5-bolt rings on Tardme recently, and 32T steel middles pop up occasionally.
Token aluminium 22T 5 bolt are around on special at $15. They are very light, dunno how durable.

It's proper 4 bolt like the Surly (lower) image.

I had found the SJS link. The starbike link are all 5 bolt ones.

IS there anyway at all to fit a 1.5 steerer into a bike with a 1 1/8 setup? (headset with super slim or external bearings)

in short no,

1 1.5" steerer is approx 38.1mm diameter, a traditional 1 1/8 heatube is 34mm diameter

Surely you could get up in there with a 1/2 round coarse bastard?

maybe machine the steerer down as well - I'm sure it doesn't really need to be that thick

if you get the clearances right you could just fit a couple of grease nipples and do away with the headset bearings too

Now you're talking! :thumbsup:

Wobbler · *by **Wobbler** on Mon 5/Mar/12 1:48pm*

Why worry about grease nipples? Just put some duct tape over the holes

I've just stuck some cheapo SH Deus cranks on my SS (xtype) but the drive side comes loose easily, anything that can be done to stop it other than sticking a load of red loctite on...? Its all fitter according to the manufacturers instructions. Its on an Orange p7 with a 68mm shell...

i have had the same issue with evolves, cranking down the extractor cap does help

as does loctite...
