Sprocket sizes, Pointy S?

[granty92]

just took delivery of my new renthal sprockets and front one is 15 and back is 45 but im sure back is meant to be 44? is this going to make and difference at all?

Best decision you ever made. Now get a good chain on it and away you go.

I suppose I will find out for myself, but my observations so far is they are very light and build quality seems good. I'm due to check/adjust the chain this weekend so happy to report back.

As for the sprocket size, in my opinion this is more useable for the SV as it gives noticeably better acceleration.

Reading Rictus's thread, it seems some Renthal's are softer in comparison to steel so aren't as durable. But then Rictus is also a big advocate of regular maintenance and I'm sure with regular care any part can be made to last longer. They are definately not 'bad' though. For me, the deal I had was good enough to go for it. A rear sprocket is relatively inexpensive to change, as long as it doesn't damage the chain or anything else.

previously I'd have said it made little difference, but having seen for myself the ware on the one off the pegaso, I can't see why anyone would fit anything other than steel unless it was for the "bling" aspect,"BAD" is a little unfair, perhaps with a different bias is more appropriate, but it's only a fool who ignores experience.

oh sh*t im scared to put it on now, i dont want it to end up like that :/

But this wasn't 'your' experience of using these sprockets. Its difficult to say for sure what the previous owner did or did not do. I'm sure in your hands that sprocket would have lasted longer.

Also there are different types of Renthal sprocket (some say the anodised is better wearing) and the effect can be different depending on the bike and riding style. A better comparison would be someone who has changed OEM for Renthals on an SV (me:)). Or if another SV owner has done the same I'm sure they can put forward a valuable opinion granty92.

Or just do some research online to satisfy yourself ...

[rictus01]

now you've got it you might as well fit it, as long as you keep a regular eye on it (after all you should be checking the bike regularly anyway) you should be fine, if you find it wearing disproportionately then it'd be wise the swap it out sooner rather than later, would be my advice, but as I said a general rule, the JT steel sprockets are the same price if not slightly cheaper and negate any issue of "soft anodizing" , it could of course be the sprocket I had was a bad batch, but I'd rather make people aware than leave then in ignorance.

Cheers Mark.

sure it would, but then it wouldn't be my experience would it :smt102, I posted what I found and the circumstances, I do or oversee more than 70 Chain & sprocket changes in the year (a good few SV's), so in all probability have delt with far more than most, perhaps you don't see my contribution as "valuable" , you're perfectly entitled to, but by the same token I believe in reporting real world facts and making people aware of them.

Your bike, your neck, your choice.

yeah i will put it on in a bit but i will check it everyday and see how its wearing, thanks peeps

Hey hey, relax. I've taken your advice. I'll be checking my sprockets and changing them if there's any sign of this kind of wear and this is all thanks to your advice.

I find that sometimes the advice given here to new riders is not equivocal enough. Its all useful but there's sometimes more to a POV. Like in this case the sprockets were on a non-SV bike that belonged to someone else with little account for how they may have maintained the chain/sprocket.

Being made aware of the potential problem is very useful. But if he ends up thinking he's gonna ride a death trap or has to go out and spend more money that's no good. However, as I said, thanks for the advice.

I don't think even hard ano on sprockets helps, ano is brittle and the high pressure of a bit of grit trapped in there then IMO will just deform the ally and destroy the coating.

Ally sprockets are OK, not going to kill you instantly or anything, just they don't last as long.

Also note that it may also be a renthal steel sprocket. I have seen these advertised but never fitted one to comment on it's lifespan.

:smt044 I think I can handle that without your guidance , besides I'm not the one with alloy sprockets fitted....:-s

you do know what equivocal means? did you not mean unequivocal which is the exact opposite, as I stated both it the linked thread and this one, what I found, how I found it and why I wouldn't recommend them, nothing unequivocal about any of that.

I agree and has already said with week regular checks he shouldn't have any surprise issues, as to your further point, it's far more dangerous if all he has is your "there fine" view and is totally unaware of the potential problems that can arise, I'd rather someone is a little paranoid about care than neglectful, but as I said, your bike, your neck, your choice.

What you mean the chain going through the back of your trainers isn't the ideal wear indicator? :p

On the plus side it is completely unequivocal though.

I dislike the idea of renthal hard anodised sprockets so much, I went to.the pain of having the rear sprocket carrier on one of my bikes, skimmed to fit a steel one. The only type available to that particular bike was a: wait as long as a piece of string from manufacturer or b: a renthal. Steel ones marketed as direct fitment actually don't at all.

Bit extreme I know, but I'd rather go to that length and be able to carry a very available Busa steel sprocket, than have an ally one that doesnt last, wearing funny, and on that bike, I know it would eat it.
