TanTan TT-X68

Delivery times vary widely, typically 4-8 weeks from order, but can be longer (up to 90 days) for custom paint jobs. Shipping to the US often takes an additional 2-3 weeks after dispatch.

Explicitly request the 'enhanced' or 'heavier' fork (around 400g uncut) when ordering via WhatsApp/email. Confirm in writing, but note that TanTan may still ship whatever is in inventory.

As of July 2026, the TT-X68 frameset is no longer in full production; the molds have been sold. However, TanTan and Seraph still have limited stock of framesets in sizes 44, 52, 56, and 58 cm, and complete bikes available. They can be ordered via websites or WhatsApp. Stock is dwindling and future availability is uncertain.

Yes, the TT-X68 frames and complete bikes are back for sale on both TanTan and Seraph websites as of June 2026, but only limited stock remains.

Complete builds range from $2,200 to $3,243 depending on components. Example: $2,191 for complete build without wheelset, plus shipping and additional parts.

The common advice is to 'size down' if between sizes, as the bike has a long reach and low stack. Use geometry charts and compare to your current bike fit.

One user measured -6° on the top cap but -1.5° on the top of the unit, suggesting the actual angle may be around -10°. Another user measured -6° with a protractor, so there may be inconsistencies. If you're sensitive to fit, verify the angle yourself.

The frame uses standard BSA BB and flat mount brakes. However, the front brake requires a specific 70mm adapter (supplied) for 160mm rotors. Some users report tight internal routing for electronic groupset wires. The supplied seatpost is -15mm offset; aftermarket zero-offset posts may fit but compatibility is not guaranteed.

Yes, SL8 thru axles are compatible with the X68 frame, as confirmed by users who have installed them successfully.

The front brake requires a 140mm to 160mm adapter (supplied with the frame), while the rear uses a standard Shimano adapter. No special or expensive adapters are needed.

No, 35mm tires will not fit safely. Users report that even 33mm CX tires almost rub the paint, and while 34mm tires might fit on the original SL8, clearance is very tight and not recommended for the X68, especially in wet conditions.

No, genuine Specialized SL8 seatposts are not compatible with the TT-X68 frame. The replica seatpost has a larger diameter, which can cause issues with accessories like 3D-printed light mounts. Aftermarket zero-offset seatposts from AliExpress may fit but can be loose and often have inferior single-bolt saddle clamps.

Yes, the Chaser rear derailleur hanger is compatible with the X68 frame; one user confirmed 100% fit.

Yes, TanTan now offers a UDH (Universal Derailleur Hanger) version of the TT-X68 frameset.

The Hy carbon seatpost from AliExpress works with careful installation (frame protector and carbon paste). It saves about 60g and can be set to zero offset. Also, the Ryet ultralight saddle (58g advertised, 60g actual) is comfortable and a good lightweight option.

Yes, the normal SL8 hanger (S206000001) works. Also, hangers from Performance Bike and Chaser are compatible.

Yes, some aftermarket zero-offset seatposts from AliExpress fit the X68. One user confirmed a specific carbon post (link provided) fits slightly looser but holds securely when torqued. It is recommended to use carbon paste.

Yes, most frames arrive with unfaced or poorly faced brake mounts and BB shells. It is highly recommended to have them professionally faced to ensure proper brake alignment and prevent creaking.

A common solution is to file the underside of the transition spacer slightly and apply silicone between spacers. Replacing the top cap with an original Specialized part (around 12 euros) also resolves deformation and creaking. Some users also replace the compression ring with an aftermarket one to prevent rubbing.

Some users have achieved build weights around 6.8 kg including pedals, bottle cage, and computer mount, using lightweight components such as carbon wheels and lightweight saddle.

Yes, many users report that the stock integrated handlebar feels soft and flexy ('noodly'). Some are considering aftermarket options like the EXS Aerover or genuine Roval Rapide handlebars to reduce flex, though compatibility and fit may vary. However, some find it acceptable after break-in.

Tantan offered a replacement frame but required the customer to pay for shipping and painting, citing the frame was over a year old. Some users consider this typical for Chinese OEM brands, though the warranty policy states defects are covered. The bottom bracket insert coming loose is a known issue.

Some users have resorted to DIY fixes like applying super glue between the frame and sleeve, but professional repair can cost around €260. TanTan may offer a replacement frame but require shipping costs. It's a serious issue that may recur even on replacement frames.
