My questions are, do spingers help or hinder a bike at 20mph?
Is the ride better? Best quality spingers? What about double springers?
Are they worth the 150 dollars?
Any input is appreciated, id like to see a discussion, opinions welcome.
I don't think some Bicycle Springer Forks have any business being on a motorized bike, or even a pedal bike for that matter.
They are a cosmetic gimmick to extend the front wheel and make it
look like it has a shock absorber.
Besides providing virtually no shock absorption, it is a really poor design.
A long thin tube bent, flattened, and then drilled at the bend point.
Now solid steel bar would be different, but it's not.
That said, I have built a couple bikes with them and those haven't failed, but the roads in Phoenix are really good.
It is front end impacts at ~20+ you want to avoid, seriously, I can't see anything on the front end of an MB giving before a Springer.
Front brakes are always a female dog with them too.
Looking for a 'good' one, I'd go by the heaviest shipping weight, good parts aren't light, ohhh, and enjoy assembling it, I have yet to do one that didn't require bending and 2 guys ;-}
If you are looking for actual shock absorption and stability I like telescoping forks.
I get ones like this XCM around the corner at the bike shop for ~$85.
Whatever you get try to make sure it has at least V brake bosses.
You can do V's for cheap and they are better than C-brakes.
Many will have disc brake bosses like the one above, but you need to change hubs and get a caliper to do Disc.
Disc is awesome if you can swing it but ANY front brake is better than none.
That's my opinion., and I'm sorry I couldn't steer you to a link a 'good one' as I really try to avoid using them.
I am sure however others have some good suggestions that fit their needs and desired look as that is important too.
Just be safe while ya have fun man ;-}
