24" knobbies? (and a cheap find @ $8/ea)

[CapnGimp]

I just took off my knobbies and put a skinny kevlar belted Kenda on my Q2, changed the 8 inch casters to the 4's that came on my SpazzG.
I only use the Q2 to ride my handcycle. I leave it outside the truck, don't WANT them to steal it but I SURE don't leave my SpazzG out there, lol.

It looks funny set for 'street' instead of muddd.
When the knobbies were on the 559's they were TALL. With the 1inch wide Kendas, there isn't much difference in sizevs a 24 inch wheel.
BIG difference in a 25 with vs without knobbies, a few inches, now I know WHY I liked knobbies so much.
I took pics...
4in vs 8in casters
24 vs 25 wheels
Girly chair (had to drop frame one notch at axles)
Manly offroad
same rims 25x1 vs 26 x 2.10 knobbies

Wow, what a retarded PT. That's where you gotta argue with them. I guarantee you'll see a huge difference with larger wheels (for the better). Unfortunately your chair is probably configured all wrong for such an upgrade, but who knows. What manual chair are you using?

I have an A4. I was going to buy a new lighter chair this year (w/bigger wheels) but I changed my mind. It just wouldn't get the use to justify the cost. (imo) Yet anyway.

But my powerchair broke down a few days ago and I was forced to use my manual for a few days. Wow, I've gained strength over the winter. The A4 is nothing for me to push now. I feel bad for cutting it down, almost. Now my problem is going too fast with not enough brake action. I can't wait for the warm weather to stay. I'm gunna' hit the trails as often as possible.

Good thing about the A4 is it's adjustable. So I hope Alberta ADL will buy some bigger wheels. They cover $450 a year guaranteed so I'll soon find out. Adjust the dump and seat a little and go bust down some trails.

I'll send ya mine no charge. Probably work since your chair is adjustable. I mean so you can keep your same dump setup. If necessary, you can get taller casters to help, I can also send the 8inch soft rolls I took off the quickie, LOTS O' life left in them. If your forks can fit them in.

[NorthQuad]

If you can, post a picture too. I have a pair of the plastic spoked rims that came on my quickie2, used them for about 7 years. Handrims are smooth. I could send them to ya if you want. Axles, bearings, the whole 9 yards, I could stand to put a new set of tires on them.
Let me know if you want them.

Were you offering your wheels to me? Either way that's super nice of you Cap! I probably won't be able to get lightweight wheels or anything through ADL but I should/hope to get some 26" wheels. It looks like there's a good selection of mountain terrain rubber for them out there.

Here are some fresh pics of the A4. Well, only two, the rest turned out blurry.

Wondering if any of you that had some fat tires had any problem with the big tires on the skinny rim. I'm running some 1.75" on spinergys right now, but looking to get some 2.2" in the near future. Just wondering if anyone had any problems.

North,
Be sure that your getting the 559 sized rims if you want to run the mtb tires.

Wow Cap, you're one heck of a nice guy. You put the MAN in humanity. I think I should be ok though. Thank you very much for such a gracious offer. I won't forget it.

I'm sure glad to know the people of CC. You all make life a little more livable. Chokes me up a little.

He puts the CHRIST in Christian, too. I really adore him. He redeems my faith in humanity.

Thanks for the tip, Rebar! I'm not even sure what 559 means, so I better go research.

Absolutely, I agree.

[Rebar]

North,
I posted a link at the beginning of this thread that explains the different sizes. That should give you a good start.

Ahhh... the Decimal sizes. 599 because it's the proper size for most mountain and cruiser applications. Good stuff, Rebar. Thanks a bunch.

Oops... 559 I meant.

You have enough adjustability here that it'd be worth a shot. Larger rear wheels, larger casters... should work! You should lower the rear seat bolt on the frame a couple inches to keep the same (or less) rear STF height. Moving from 22" to 25" wheels is significant. If you don't add larger casters your front angle will be greater, and a more problematic issue will be the angle of your caster stems (perpendicular to the floor = good). Good thing you have an A4 to tinker with. I had one as my first manual chair.

I like those goofy grey ones at sportaid. They are a little softer and easier on my hands!

Haha... yeah, that's understandable. I still think they look goofy compared to bike tires (obviously a subjective opinion).

Mtn bike tires *do* soften up after they're broken in...

Like so many things. Lol.
