Paragon is opening the second quarter of 2025 with an exploration into an additional style of headtube: the IS52/IS52. With the buzz still flying around for internal routing, and multiple requests from our clientele, we have decided to pursue this as a stock option for our customers.
Product Details:
Materials: 6/4 titanium or 4130 steel; both materials will have identical features. We chose a slim, simple profile to maximize accessibility and to allow frame builders to adapt the headtube to their building style.
Sizes: 90 – 280 mm, in 10 mm increments
Pricing Range:
Steel from $26.95 (90 mm) - $114.95 (280 mm)
Titanium from $98.95 (90 mm) - $321.95 (280 mm)
Ordering:
We are targeting an early July release date and will accept orders starting Monday, April 14th.
There is no limit on pre-order quantities, but larger quantities may affect lead time
Orders must be placed by Monday, April 28th at 3 pm.
A 100% deposit is required; we will email you an invoice for payment upon receipt of your order.
Your deposit does not include shipping charges; it will be calculated and invoiced once your headtubes have been manufactured.
Your headtubes will be shipped out after full payment has been received.
We can only guarantee headtube availability if you place your order and pay your deposit by the deadline. Otherwise, you may have to wait for future production runs.
Our new flat mount steel dropout, DR2078, is compatible with SRAM's Full Mount Derailleurs and Universal Derailleur Hanger. The left side has an integrated brake mount for 140 mm (direct) or 160 mm (with adapter, not included) rotors.

It's featherweight, it's dimpled, it's our new titanium barrel adjuster! It's a delightful addition to and has the same dimensions as our as our adjusters made out of aluminum, bronze and stainless steel:
Heads up! To help keep manufacturing costs down and maintain the functionality/strength of our steel 10 mm low mount dropouts, they're now made out of 1018 steel instead of 4130, and have fewer relief features.
We've added two new options to our line of titanium dropouts that are compatible with the SRAM Full Mount/UDH system.
Our first new release (above) has a 140mm integrated brake mount (160 with adapter) on the non-drive side, giving frame builders more options for building with the UDH system. The drive side has a 1-3/4" OD and is available in concentric (DR0078, 0 mm offset) and eccentric (DR0079, 0.5 mm & 1 mm offset) styles, allowing for precision wheel alignment in any circumstance. We emphasized the refinement and aesthetics of this dropout, intending it for broader use across many styles of frames.
Our second release has a left side frame component with a weld-on flat mount brake insert intended for 140 mm rotors (160 with adapter). The chain stay tab is extra-long to allow for clearance of 1" stays if needed. The frame builder can simply cut off the excess if building with 7/8 stays. The right frame component has a 1-3/4" OD and allows for rack mounting with eyelets (DR0104) or without eyelets (DR0105). This dropout will be offered in titanium only. See our DR2102/DR2104 for a similar design in steel.
Don't know which one to choose? You can't go wrong! Both styles are sleek with a low profile, meet all of SRAMS specs, and integrate beautifully into a frame. As always, please reach out with any questions you might have.
We've added more options to our selection of M5 x .8 barrel adjusters. Both styles (dimpled and knurled) are now available in aluminum, stainless steel and brass.
