One of the bike parts that happen to take the most hammering is the crankset.
Basically, they are designed to withstand tough conditions. Nevertheless, not all cranksets out there are strong enough for rough riding. It all depends on how you intend to use the bike.
If you are looking for a good crankset for your road bike, the SRAM NX GPX Crankset or TRUVATIV Crankset would be a good pick for you. But, which of these cranksets should you choose?
We will be discussing their comparisons in this GPX vs. BB30 crankset review article.
Let’s get it started.
GXP Crankset vs BB30 Crankset
These two cranksets are both incredible units to have, and their performance is also assured.
They are worth purchasing, but it is important to understand the difference between them, so you have an easy time choosing between them.
The size of the crankset is one of the things that people consider when choosing.
If you are keen, you will notice that the GXP crankset comes smaller in size at 12 by 7 by 7 inches.
Conversely, the BB30 crankset measures 17.91 by 13.39 by 10.43 inches.
The BB30 crankset is also heavier than GXP crankset by 91grams.
In terms of the chainrings, the GXP comes with an X-SYNC chainring that is coupled with CNC-machined teeth.
It’s also designed to prevent the chain from flying off into the ether while keeping it turning over.
The thick teeth are machined to interact seamlessly with the outer and inner chain links. This is meant to offer you a powerful and smooth pedaling.
On the other hand, the BB30 crankset offers you a Glide R chainring that is aligned to pick up rivets to the chain pivots pins. It also assures you of double shift opportunities.
The cost of the crankset might not be such a big deal to most people out there.
However, you might want to consider the price of the crankset if you are on a tight budget.
Most riders out there consider that the GXP Crankset is the ideal budget-friendly option if you compare the two.
Both the cranksets come with a sturdy aluminum construction that assures you of a lightweight and durable unit.
They’d both be a good pick for road biking; at the same time, they perform well when climbing or going down steep terrain as well.
The SRAM NX 1x GPX Crankset comes with some amazing features and specs, which make it an incredible unit to have on your bike.
In terms of its size, this unit measures 12 by 7 by 7 inches, and it weighs around 780g.
It might be lightweight, but the crankset can perfectly take a beating. Furthermore, this crankset comes with a sturdy aluminum construction to easily withstand the rough riding conditions.
There’s also an X-SYNC chainring that is almost similar to the high-end offerings of the SRAM series.
This is then coupled with the CNC-machined teeth that can easily alternate between the wide and narrow.
In turn, this will keep the chain turning over while preventing it from flying off into the ether.
The X-SYNC chainring features individual teeth that are machined to seamlessly interact with the inner and outer link of the chain.
As a result, you can be sure of enjoying a smooth and powerful pedaling whether you are climbing or going down steep terrain.
Keep in mind that this crankset is perfectly compatible with the SRAM GXP bottom brackets.Basically, it will work with all the SRAM 1x drivetrains.
Another aspect worth mentioning about this crankset is the price point. Many bikers have labeled it the best budget-friendly option if you want a reliable crankset for your road bike without spending too much.
However, one issue that you should be aware of is that the bolt on the non-chain ringside can get loose if you don’t re-torque it. Other than that, this is a very reliable crankset to have for your bike.
