Best Shimano CS-6700 Ultegra Bicycle Cassette (10-Speed) Deals

Customer Ratings:

My bike is outfitted with Dura Ace everywhere except the cassette, because this cassette cost 1/3 what the DA cassette costs and will last 3-4 times as long, for a tiny weight penalty. This is a no-brainer.

I bought this to replace my SRAM red cog after using a chain for too long and wearing it out. The weight difference is negligible and it actually shifts better IMO. I used to think all te components needed to be the lightest, but man it's expensive to think that way!! You can't beat the price either, locally in Miami thiis sells for $110 and the SRAM for $230 so this was a natural choice for me. Buy this instead of SRAM red or dura ace. Oh and a

Amazon is the bomb!

I have the 11-25 version and found it to be smooth shifting and lightweight. I ended up needing a 28T for hills and replaced this with a SRAM PG-1070. I would have given the Ultegra cassette 5 stars, but Between the two, I'd say the SRAM is a better value. It's a little lighter and a little cheaper with no noticeable difference in performance between the two (FYI: both were used with the same other components, an Ultegra 6700 series drivetrain).

Bought this cassette in anticipation of some sustained climbs. Normally have a 11-25 Dura Ace cassette but saved some money by going with Ultegra. Only a few grams heavier but offered the 28 cog to get me easily up the steep pitches. Shifted fine as you would expect.

After riding Dura Ace & Sram cassettes I always come back to the Ultegra cassette for their reliability, durability & price.

Best value out there.

Reviews of Vittoria Ultralite Tube

Customer Ratings:

I ordered a pair of these, the rear one popped between 80 & 90 PSI as I was still inflating it, & the front one popped about 15 minutes after I inflated it to 100 PSI. Both wheels had rim tape & brand new tires, so I'm pretty disappointed at a grand total of 0 miles I got out of these.

I've had these tubes on for about 100 miles and still no problems. I wouldn't call them "ultralite" as advertised, i think some tubes go for less than 95g but they are light enough. They hold air well and are sturdy enough for NYC streets. I'll be purchasing another couple of tubes if I they keep me rolling over 500 miles. They're from Vittoria so you can't go wrong.

UPDATE: 5/6/2012

So I finally got a flat on this tube. I'm satisfied to say that this one tube kept me rolling well over 500 miles. Don't know the exact number but the quality of this tube is definitely there. It took one nasty pothole, downhill at +30 mph for my rear tube to pop. I can't find the hole even though the punctured tube keeps releasing air. The tube itself is still in tact, giving me an opportunity to patch it. I was 100% confident that I was going to be able to finish my ride until that flat. I was able to fix it right away though. I just came back here to order more. +1 star.

Hard to give a tube a review but I haven't had a problem with over 1000 miles so it's doing it's job. I'll start weighing different tubes I use which would probably be more helpful.

Honest reviews on Vittoria Ultralite Tube

So far no issues, I have driven about 300 miles on those, mostly on trails. Stem is firm, they fit well my Shimano R500 wheelset with 700Cx24 tires. It holds air ok between my weekly rides 50-70 miles. Though, I might occasionally add some air, like once a month just to keep firmness, as I ride them at 110-115psi.

I use a Zipp 808 as my rear wheel. Unfortunately, even 80mm Presta valves aren't long enough for that wheel, and no one seems to make 100mm valves. To avoid the mess that are Zipp's valve extensions, I bought the 51mm Vittoria tubes with removal cores and paired them with Vittoria's (ridiculously overpriced) 62mm valve extensions. I figured it would be best to keep manufacturers the same when pairing tubes/extensions.

For that application, these tubes (and the related valve extensions) work great. Beyond that, though, they're fairly standard high-quality tubes. Unlike Specialized tubes, these aren't threaded the whole way down should that matter to you.

Reviews of Kenda K40-HP Street Wire Bead Bicycle Tire, Gumwall, 26-Inch x

Customer Ratings:

A pair of (37-590) Kenda K40 "gumwalls" was used to refresh an older Free Spirit bike. Tires mounted reasonably well considering the condition of 30-year-old rims, but make sure the bead is in fact seated evenly before inflating to recommended pressure. A small rib should be visible just above the rim edge, and will help you judge if tire is in place.

My friend is a very happy camper now, and so am I for being able to help out.

Overall, these tires are good enough for the price, mount, look and roll very nicely. The 26 x 1-3/8" was very hard to find locally, and thank you Amazon for keeping the stock.

* Note: One-star reviews for these elsewhere on Amazon are not all deserved. These are *NOT* MTB-sized 26" tires despite a "26" appearing in the size read specs carefully.

** Tires came in two large flat packages, but could have easily fit in one. This means the wire beads were not bent even a slightest bit (vs. if two were packed in the same box). Amazon could have easily saved on shipping, but didn't this time, which is a nice touch!

I ride a bike that was sort of retro when I bought it in 1973 at the height of the ten-speed craze. It is a hub 3 speed. Tires for it are not common any more. I bought this tire because it has a higher max rated pressure, like 80 pounds, so I could put 65 pounds in them like the original Raleigh tires had when I got the bike.

I began riding it again regularly, like 6 hours a week, when it is above 40 degrees, about 4 years ago, so the tires do get quite a lot of use. I had the exact tire as this one just previously. It looked just slightly worn when it gave out after 7 months. The same thing happened to me with a different, lower pressure, Kenda tire after a year and a half of use. What happens is the cord in the tire rips and the tube starts to squeeze out. I didn't over-inflate the tires.

Nothing happened immediately before the event. I hopped on the bike to get back home from where I was. Everything seemed normal for about five minutes. Then a noise like something was stuck on the tire started, and got noisier fast. I got off to take a look. The hole in the tire expanded, and the surrounding area bulged, as I watched. I recognized this as what happened to the previous tire. I let out most of the air in the tube so it wouldn't blow up and walked about two hours home.

The tire was hardly worn, so it wore well. 7 months of use is alright with me for the price. But I never had a problem like this with tires before. Before this, they wore out and I switched tires.

This June, the same type of tire failure occurred on the front tire, where the other two were on the back, so this is at around 2 1/2 years of use. The tread is not very worn. The front still had the low pressure K-40 (versus this high pressure K40-HP). Since all the weight is on the back, I was able to lower the front pressure to 30 pounds, enough to keep the tire from looking flat, but so the tube and tire liner wouldn't bulge through, and I could ride the bike home. It is just hard to ride that way.

Since no one else has this type of failure, I'm thinking of what could be different. Maybe it is the anti-puncture tire liners I use wearing the cord from the inside by rubbing friction. They are are lot tougher than rubber tube.

Like another reviewer mentioned, each tire came in its own box. In my case at least, the boxes were a little too small.

During mounting I noticed a few spots where the side wall had an inconsistent thickness. I inspected the other and found the same thing, assuming this was normal I mounted them and inflated. Everything went ok with the first one, the bead seated nicely and I set it aside. While mounting the second I heard a loud pop, the 1st one had busted right through the sidewall. I continued with the second. After inflating to 70psi (I was too afraid to go to the recommended 90) I saw waves forming in the sidewall.

I would not recommend these tires at all, it seems the quality control leaves something to be desired.

This 26 fractional tire does not fit a modern 26 mountain bike, the description should state exactly which size tire rim it should fit

I put these tires on an old singlespeed conversion and they look great. The wheels were originally mounted with 26 1 1/4 knobby tires. These are slightly thinner and more appropriate for mild road use. I ride my bike about 10 miles a week on clean, smooth roads.

The gum walls look very retro and unusual. They definitely improved the look of my bike enormously.

The tread is pretty mild and they roll easily on paved roads. I haven't had any trouble with the occasional small puddle or patch of dirt and leaves.

I would not use these in an area where glass, thorns, or potholes are an issue. These don't look like they could handle serious riding and would most likely pop a tube if they were ridden in hard situations. Don't expect to go jumping off sweet ramps with these.

They installed very easily and I think I'll get several hundred miles out of them. I recommend these to someone looking for a cheap way to get a bike rolling for mild to moderate use. If you are a serious rider or ride in adverse conditions, spend a little extra and get a decent brand name tire.

Okay, truth in advertising here: I haven't ever used latex tubes for road bikes, BUT I have used them in my mtn bike, and they were fantastic!

Years ago, you may have seen an ad in the bike mags (MBA maybe) showing a guy stretching one of their wicked latex tubes over a wine bottle that had been purposely broken off with a church-steeple like shard of viciously upthrusting glass. That ad sold me, and I put them in my mtn bike tires.

Here's what I found with the mtn bike tubes: 1) The latex tubes, especially on a mtn bike, are significantly lighter; 2) they are far more resilient/stretchy than butyl; 3) yes, the physics on rolling resistance is correct; 4) I ran my mtn bike tires at 25 30 lbs for at least 6 years whilst riding quite hard and fast on very technical single-track trails filled with rocks and roots, and on very steep, fast rocky fire trails all without getting a single flat (granted I weigh 144 lbs but you get the picture).

Interestingly, nothing good lasts forever and eventually the tubes failed -on the same ride, within 1/4 mile of each other. My conclusion was that they have a lifespan and as manufactured products these were incredibly consistent. In the case of those tubes, it would be a good idea to change 'em out after about 4 years, whether they had failed or not. That's a pretty impressive duty cycle in my book.

Bottom line is about low weight and extreme durability. Hidden within that durability may exist the opportunity to run a relatively high pressure w/ less flatting from road hazards, but one should verify that w/ the manufacturer. I loved my latex tubes and will be using them again.

Whether a quick hour ride or 3 4 hours in the saddle, in my opinion the value of latex vs. evo tubes is not worth the cost. I do not notice anything different with the ride.

I have run this tire on two dual sport (enduro) bikes for several years. I've tried Shinko 244 and Michelin Karoo's. Both of which wore out in 3000 miles or less. I can get 4500 to 6000 miles on a K270 Kenda. The 6 ply rating means, for me, no flats as of yet. My bikes are usually used for off road trails and these tires are great for dry pack, rocks, gravel roads, wet and dry steet use. They do ok in mud as a 50/50 tire but not as well as a full knobbie would do. Dunlop 606's are the best DOT knobbie for mud. I'm on my 3rd Kenda rear tire with my Suzuki DR650. They are loud on the freeway but all knobbie type tires are. Usually these tires sell for $65.00 so shop around...

Honest reviews on Kenda K270 Dual Sport Tire - Rear - 3.50-18, Tire Construction:

I say 50/50 tire, but in reality, unless you are going up a mountain on wet clay, this is a great off road tire. I ride every day, 365 days a year, on and off road. This tire corners nicely on pavement, isn't loud to an extreme like my previous tires,(D606). Kendas need to warm up a bit so don't get excited if you squirrel after rolling on to heavy within your first mile or so. A pair of these will do you just fine for the everyday and are dandy for trail work. Note, Not a Sand tire, and if you are a Nube, Let some air out before you hit the trails.
