Sun Helix TR25 Custom Bicycle Wheel Set

Description

The Sun Helix TR25 rim offers the performance and tubeless ready function of higher end rims, but at an attainable price point.  The 20.8mm inner works well with a wide range of tubeless and standard clincher tires.  So if you decide to stick with inner tubes, you won’t have to struggle, these mount up easily with a tire and tube just like rims used to before tubeless ready.  Overall, the Sun Helix 25 offers an incredible value.

What Others Are Saying…

We will build this wheel set with any of the hub options above, but the standout from the list are the sealed bearing Speed Tuned ST170 (front) and ST300 (rear) convertible MTB 6-bolt disc hubs. The ST300 features 21 points of engagement with a solid freehub design.  The freehub can swap out between Sram XD and Shimano HG or Shimano MircoSpline (12TA only), (in case you swap bikes), and the end caps are convertible between a bunch of different axle standards.  True, the 21 POE has been eclipsed by many other higher POE count hubs that are currently in the marketplace, but it’s still higher than DT’s ubiquitous 18 POE Star Ratchet piece found in 350 hubs.  Last but not least, these hubs feature superlative sealed cartridge bearings that spin smooth, and will hold up for the long haul.

In “stock” form, these wheels are built with Sapim Leader black stainless steel 2.0mm (14g) J-bend spokes in a 32 hole, three cross configuration front and rear.  These spokes are an upgrade over most “new bike” spokes.  Small details make big differences with regards to spoke wire, and even though there are lighter weight spoke options available, these straight gauge spokes still feature top quality stainless, with a precise finish that allows for precise wheel building.

There is an option to build these wheels with Sapim Race Double Butted 2.0/1.8/2.0 black spokes in a 32 hole, three cross configuration front, and rear.  Sapim Race spokes offer legendary quality and performance.  If you didn’t know a thing about spokes, know that your wheels would come with a really top-notch spoke product.  That being said, we’re offering a spoke upgrade option, in the form of Sapim DLight 2.0/1.65/2.0 spokes.  There are two great spoke manufacturers in the world, DT Swiss and Sapim, (in alphabetical order).  Essentially, you might be able to find a spoke product that approaches their quality, but you’d be hard-pressed to find a company that makes a better spoke product than these two.  All their spoke products, from straight gauge to their elliptically bladed and butted products, are all the best of the best.  Sapim Dlight spokes will perform at the same relative level as Sapim Race or DT Competition spokes but will shave off approximately 75 – 80g from the wheelset.

The Sun Helix TR25 is a stellar wheelset option, in a field that’s composed of some of the best aluminum alloy MTB rims ever.  Given their level of performance, they are an unbeatable deal, (coupon codes here).  We’re not joking around here.  If you don’t have a lot of time to research all the rim options in the marketplace, if you don’t have a lot of money, and if you can find this product page, maybe that’s Magic.

Should you buy this wheelset?  Entirely your call.  Should you watch this short but sweet rock climbing video?  Absolutely.  One More Fun One.

Make That Two.
