Thread: TiLite titanium tubing diameter

  1. #11
    I've weighed the frames with casters, upholstery, brakes, adjustable back, and axles on my wheelchairs. Quickie TI was lighter. I don't recall the exact values. But I can repeat. They had the same upholstery, casters and brakes but different axles and back hardware. Perhaps the frames are the same weight but the axles and back hardware differ. If that is the case, then you may be right on a technicality but what difference does it make in reality? Because the axles and back hardware can't be interchanged. You have only one choice. The exception would be if you swapped out the folding back for a fixed back, which I can't do for the sake of transportation. Bottom line, My shoulder can tell the difference when putting the wheelchairs into the car. The Quickie was much kinder on my shoulder than the TR in a like comparison. Why else other than real life issues like transferring into a car do we care about weight on an every day chair?

    Yeah, other than lifting the chair, I don't think a couple pounds one way or another makes any difference to the pushing experience. Considering the weight of the occupant, a couple pounds is an imperceptibly small % of the total rolling package. Pushing agility/efficiency is all about geometry and rolling resistance IMO. I really liked the Ti, a lot, but lost too much confidence in it when it broke. Didn't even want a replacement. Got a Lasher instead. Been pushing that chair for 10 years this year. Still as solid as a rock. 1.375" tubing, no flex, fully featured, and light af!

    I have a TR frame in the closet...it is like 2lbs (or ridiculously light).

    Re the Quickie...I'm sure it is light, but I had a look at one and it scared the crap out of me. I'm a 200+ lb'er though, smaller folks or those with less mechanical fatigue experiences may be confident in its structural integrity.

    Probably true that a 1" mono tube is asking for trouble for someone putting a lot of demand on it.

    Wish they hadn't given up on it. There were some frame failures (mine was the axle plate) but they could have addressed any issues IMO. Tubing strength is heavily influenced by wall thickness, too. OD is just one aspect. I wouldn't be surprised if it were a simple business decision to get out of the titanium game. It's a bitch to work with, reimbursement had become flaky, and properly engineered aluminum tube (like the oval tube on the Q7 and it's varying wall thicknesses, etc) can be just as light, or lighter, and with proper heat treating strong enough not to make a difference to a wheelchair user.

    Speaking of titanium, I saw a Ford Fiesta Titanium on the road today. I know Silver is a little too pedestrian for a car glorification, Gold has a negative ghetto connotation, Platinum is a trendy designation lately...but Titanium? Does that mean you are a cripple driving a clown car if you own a Fiesta Titanium? lol Anyway, I was thinking of putting a Iron Oxide emblem on the back of my winter-duty Ford to keep up with car naming trends.

    Ok...back to wheelchairs
