Tern Link C7 Rim and Tire Upgrade, and Compatability Questions

I'll just jump right in..

I bought a Tern Link C7 and I plan to upgrade the tires and rims. I've already found what seem to be some good rims and tires for it. My questions are if they are compatible with my bike, and also which rim and tire would be best suited for my purposes. Also whether these rim and tire combinations are compatible with each other.

First I will get into what I need them for: I will be commuting quite a bit. I live in the city. I will mostly be biking on paths but with the occasional excursion into the city. My bicycle is my only source of transportation. I am looking for something durable and fast. I would like to be able to get where I need to go quickly and with as little energy expenditure as possible. Where the tires are concerned, I would like them to be optimally puncture resistant. Also, keeping the weight down would be great.


The rim company I found is 'Spinlitecycling'. There are two models I'm looking at that were designed for recumbents, but as far as I know can be used for folding bikes as well. The choice is between the 'Velocity Aeroheat AT' or the 'Velocity Aerohead'. (Also, I'd like to know tire compatibility with rims. I'm looking for the thinnest width tire possible and like I said while keeping good puncture resistance.)

http://www.spinlitecycling.com/recumbent_rims.htm


The tires I'm looking at are either the Kenda Kwest in either 20x1 1/8 or 20x1.5 depending on compatibility of rim etc.

Or the Panaracer Minits Tough, or Light. (Also what's the difference between 'folding' and 'non-folding' tires?)

http://www.amazon.com/Panaracer-Mini...ef=pd_sbs_sg_5

http://www.amazon.com/Panaracer-Mini...d_sim_sbs_sg_7






There are a few other tires I was looking at but they aren't really within my budget, plus I'd rather the tire pressure be 100psi or above for speed. The two above are my first choices. I will list these anyway in case somebody knows something I don't:

It seems strange to me to buy the cheapest model and upgrade these parts instead of just buying a better bike to start with such as the P9.

What benefit do you think new rims will provide?
Fast and puncture resistant tend to at odds with each other, best have a look over sheldon brown's website for general information. Your requirements are so broad it there's no clear recommendation to be made other than some variety of Marathon tyre, i.e. a general purpose touring tyre with decent puncture protection.
But really you want to start with your bike as it currently is: how do you find the ride in terms of comfort? What psi do you run your current tyres at?

I say either way is OK.
Personally for me; the fun of a hobby is to do the upgrades and customize.
I've dropped $600 into my $600 Dahon Mantis, but now it's the way it should have been from the factory.

I often drop 2+ times the value of an item into making things perfect, then when its done, I sell it and move on to a new hobby.
Cars, RC vehicles, scooters, guns...I find almost nothing is perfect from the factory.
If everything was perfect, we would have nothing to complain about or have opportunities to make money and buy more imperfect things.

Since you can't change a woman as they are confused as to who they are between the ages of 12 to 65.
At least I can change my hobbies to my liking

I tend to be the same ttakata, but besides the better components on all the other varieties of the Link there's also better frame parts including the handlepost design. So I'm not convinced the C7 is a great starting point.

Jeez man, I was just joking, hence the smiley face after the comment.
Are you telling me you have never made a joke about the opposite sex, are you an alien?
If a guy can't make fun of the opposite sex, what's next?
No drinking at a frat party, or speeding in a sports car?

Dude, in the country I'm in (USA) it's considered a no-no. Where you are it might be acceptable,...hmm???
Besides,...you'll live. I know I will.

Back to original topic:
- re. the rims, I would keep the original, use them until they wear out and then replace the entire wheels (change rear for a cassette hub)

- re. the tires: I'm not sure narrow tires is the way to go... smaller wheels like 20" have worse properties when it comes to riding over obstacles or potholes compared to large wheels (e.g. 28"), that's why they came up with 29" MTB. The wider tires with higher air volume can compensate for this disadvantage by offering some "suspension".

I have a tern Link D8 for a few days and I'm completely satisfied with how it rides in the city streets on the stock 1.75 Schwalbe Citizen tires.

Don't do it here. It's in the forum guidelines that you agreed to when you joined here. So stop it.

Getting Kinetix Comp wheels is an excellent bang for buck. The Velocity rims are also good, obviuously you need to look careful to get the right number of holes.

Kenda Kwest is an entry-level tyre, not fast, but not bad.

Minits Tough are good for the back, Minits Lite for the front. I pair them with Slime tyre liners for puncture resistance. However if you do use tyre liners you need to feather the ends to a thin taper or the sharp end cuts will wear holes in the tubes.

You need to get rims and tyres that are decimal, not fractional inch sizes. eg 20" x 1-1/8 is not the same as 20" x 1.1" or 20" x 28mm. Different rim sizes. Only the decimal inch/mm size will fit the Tern. 406mm ERTRO size. Same with tubes.

The schwalbe citizens are really good on the street and not exactly cheap ($31 usd each) but the ones that came with the c7 aren't citizens and i never heard of these schwalbe impac tires, I can't even find them on their own website! But I googled them out and they are like half the price of the citizens, so that'll give you a gauge on the quality of them or how long they'll last.

use the tires which came with the bike, they are not the greatest but better than a lot of bargain others. Tire width the narrower the faster it feels, but the reality is not always catching up with that feeling stuff...lol
I am out of 20x1.35 MArathon Plus which have an excellent puncture resistant and almost acceptable weight penalty ( will get new ones in a week or so )
Dont pay too much attention to profile, your contact patch is like a quarter and all that fancy profile design aint gonna make too much difference.
The lighter the tire, the higher the pressure, the faster it will be .... generally speaking again, but on the other hand high volume tires like the Big Apple have turned the tire world upside down, as they will float and are not that much slower, in some instances faster as they give you a better ride....

Dont agree with those comments, but also aint no fan with over-correctness. I do make fun about myself rather than others :-)
Only try to type things which I would say any person straight into his face, except if he is 6 foot plus and much stronger than me..lol

To the OP, sorry for sidelining your thread. I have now become "that guy" that throws a thread off topic, my bad. Well with close to 100 posts, it was bound to happen. A joke gone wrong, I was not aware this forum was so serious.

Back to the original question.
So I don't have a tire recommendation from my experience. I've taken my Kojaks on grass and my Primo Comets on rough gravel but since they have no tread I would not recommend them because they are very sketchy in sand.

My hardcore MTB friends tend to swear by tire liners over a tire with added protection. Seems to make sense; tire liners are very tough plastic. You might want to give them a try since they are cheaper than a quality tire. I'm not sure if they are made for 20" tires but as long as they are the proper width, you should be able to cut them down to proper length and sand down/feather the edge so it doesn't cut your innertube.

Non folding tires have steel beads to help keep it on the rim, I'm not sure if you can fold a 20" steel beaded tire like you can with the larger tire sizes. A foldable tire has a kevlar bead so you can easily fold up the tire for storage, very helpful if you keep a spare tire on the bike for touring. They are lighter but more expensive.
