Crankset???

ApolloB

Hi there,

Just when I thought I had a bit of an idea of what I was doing, I now seem to be missing something?

I'm looking for a Crankset/Chainset for the Shockwave 9.5 on eBay. Trouble is the only one's I seen to find have 2 or 3 chain rings/Sprocket on them. Now unless I've got it wrong I need a single Chain Ring as the frame will not have a front derailer?

Please educate me on this.

Also I'm thinking if I was to get a front chain ring with say 42 teeth (Larger) it would make bike faster??

Thank you

Where do you start? You're missing a lot.

Having legs like Chris Hoy might make it move. I wouldn't worry about 'faster'.
But most single ring cranks will be DH type things

You could get a double or single and take some rings off.

You will need a chain guide, along with lot's of other stuff.

Going back to your other thread - you have the wrong frame for what you want to do with it.

Unless you are giving up on the park and going to become a DH rider, I would sell it and buy something suitable.
Seriously.

+1 to that. If it does get built you'll end up with a tank which will be absolutely no fun whatsoever around the park with the kids..especially with a 42t chainring :shock:

Hello

I already know I bought a DH Bike frame and what is should be used for but it’s what I wanted. May be I will try a bit of DH once bike is finished I don’t know at this point, I already do Scuba Diving and Hang Gliding

Not sure how Chunkers1980 comment is suppose to help or educate me??? But your right mate I am missing a lot that’s why I joined this site, I thought it might be helpful. Remember I’m only asking for help on how to put my bike together not what I should use or do with it.

I'm not worried about going fast either but some rings I have seen have 36T and more so I'm trying to work out why I would use a small or larger ring, what are the benefits or disadvantages for me. Gearing info.

Thank you for the link to winstanley and the advice on removing rings; I didn’t know you can remove rings that’s why I asked you experts.

I promise I won’t ask for anymore help.
Seriously.

You'll tend to find that on here, open questions sometimes provoke frustrated/narky replies.

In short, yes, the larger your chainring the faster the bike. Or put another way, the higher the bike will be geared/harder it will be to pedal. Unless you're ONLY riding downhill, i wouldnt recommend anything bigger than a 36T. The rear gears should give you enough range for most riding apart from really serious uphill stuff.

The link to Winstanley's gives you the idea of what you need, but you also need to check if you already have a bottom bracket and, if you do, that the new crankset will fit that.

Apart from on cheap chainsets, it is common that chainrings can be removed, so you could buy a triple or double and remove those rings you're least likely to use. But as mentioned above, you'll then need a chainguide of some sort to keep the chain from coming off.

I'd say keep posting your questions, but one at a time otherwise you'll end up with a load of essays like this....you're in the Beginners section, so some replies may have been a little harsh to be fair.

Not harsh, realistic.

For the riding the OP is suggesting there are plenty of bikes and frames suited to riding round the park and being able to tackle DH trails. Riding a DH bike on XC trails or 'round the park just isn't any fun and what's the point of spending a load of time, effort and money on something that's not enjoyable?

I ride mine on the road about 2km to my local lifts and there's nothing enjoyable about it. I run out of low gears as soon as there's even a slight uphill - (and I'm running a 34t ring) - obviously the 12-27 cassette doesn't help either. All the angles are wrong, the seat is a pain in the arris, literally and the tyres are just ridiculous..and it weighs a ton

He could take his pick of AM frames and still have the fun and experience of building a bike but it would get used more and be more enjoyable. That's all.

You could have a look at this;

Not much advice on how to put it together but have listed all the parts and the order I did it all in. Obviously not a DH bike but a lot of the parts are similar to what you'll need. It has a DH crankset...although some on here will beg to differ

...all the prices are at the end of Part #4 if you're interested

I think there's a spate of people misunderstanding completely what a DH bike is.
It's not a bike that is "best" at going down hill. It's a bike that has racing down steep mountains as it's ONLY purpose in life.
They do not do so well on the flat. They do not do uphill, at all. They weigh a frikking ton.
It is the least useful of all bicycles, since it does ONE THING, at the expense of all others.

You have the wrong bike. If "maybe" is as certain as you get, then you really aren't going to like what you end up with.
