Great service from Mantel
Even though my bike has an Ultegra groupset, I normally use 105 cassettes as they are cheaper and only a few grams heavier, but with Mantel's competitive pricing I can get this for the same price as a 105 cassette from other suppliers.

Top class cassette
By now no secret but this is an absolute top notch cassette at a decent price. Makes Durace totally obsolete as far as I am concerned.

And what can I say about MANTEL! Received the day after I placed my order, unbelievable!
Yes, very good development, if you maintain your chain well, no worries, no noise! I use this development to punch in the bumps and small hills.

Great value & quality
Lovely quality cassette, very little difference to my last Dura ace unit, just slightly heavier and not quite as bling, the change from 11-28 to 11-30 has been great as the 11-21 block remains identical (11,12,13,14,15,17,19,21) and only the lower 3 gears being 1 or 2t different, great service and price from Mantel. Took about 3 days from ordering to been delivered by UPS (I'm UK based). Thanks

Fantastic product & fast service from Mantel
Gives you all the range you need when the road points up. Super smooth shifts and no need to be riding around with a 28 as the largest sprocket anymore. If you have standard Ultegra r8000 rear derailleur that should be fine, just new chain only.

Fantastic quality cassette
The ultegra 11-32 cassette is fantastic quality, fairly light weight with crisp smooth shifting. Excellent. Mantel was the best price I could find online too and delivered quickly.
Pros & Cons
5 / 5
Very good, as expected
Expected. A 34-11 gearing like this is for climbing hard mountains and long climbs (Alp d'Huez, the Lakes, Angliru...). If you are a normal mountain climber, a 32 or 30 is better. With this one you will lack the sprockets to ride or to climb 7-10% climbs at a good pace.

Top cassette with the right gears
11 speed cassette is used on a SPEED PEDELEC with rear wheel motor. The ratios are excellent, always a cadence to match the speed. Durability has yet to be experienced.

Good value for money
Especially in combination with a new chain, a very affordable cassette! Did 7,500km with my previous cassette (also ultegra) without replacing the chain. Will replace my chain a little earlier this time though, then the cassette should definitely last even longer!

The longevity is of course also dependent on the chain care, but the cassette forgives much. Had them last 8 chain changes in use and it would be even more in it.

Before I used to ride an 11-32 and a friend suggested me that in Madrid for the posts that there are with an 11-30 I had enough, well after testing it thoroughly it has exceeded my expectations.
