FAQs
FAQs
Is the frame compatible with SRAM T-Type (Transmission) derailleurs?
The short answer is yes, but some chainring sizes may not be suitable for some frame sizes.
Please refer to this chart.
The longer answer and a bit of background as to why this chart is needed:
When the Big Kev frame was developed, the T-type (Transmission) system had not yet been announced by SRAM, and the dropouts were designed to work with the UDH hanger while maintaining our regular "hooded" dropout design. When we learned about the T-type development, the Big Kev was already in production and it was too late to make any changes.
The T-type spec prescribes that a certain amount of clearance is needed for the derailleur's "full mount" bracket to be able to swing forward in order to accommodate a range of chainstay/chainring/chain length combinations. This forward swing may be impeded by the outside hood of the dropout on some frame size/chainring combinations on the Big Kev - so we made this chart to help identify the combinations where interference may be possible and extra diligence is needed during setup.
Always use the SRAM AXS app, online calculator, or the Eagle Transmission user manual for final verification of chain length, setup cog and setup key position.
Welcome Big Kev to the Curve Family
Big Kev is the progressive gravel bike you have been waiting for. Curve was one of the first brands to bring gravel bikes to the market. Now, it’s time for gravel-plus.
Designed as the new benchmark for adventure cycling, Big Kev features wide 29-inch tyre clearance giving you the comfort and confidence for weekend gravel missions or the reliability and speed to tackle bucket-list bikepacking adventures like the Tour Divide.
It’s Time for Gravel-Plus
A larger diameter means more comfort on rough terrain. With Big Kev, we have committed to the 29-inch wheel platform. With the new Ride 415 carbon fork, Big Kev is optimised for 2.1” tyres*, with a maximum width of 2.35” on the rear** and even wider, up to 2.4”, on the front for extra control.
For less rugged missions or extra speed on fast gravel tours, you can slim down to 2.0” tyres for faster rolling. Gravel-plus means you can take on more than just pristine gravel roads. Big Kev gives you the flexibility to get more adventurous.
* Tested with a Vittoria Mezcal 29 x 2.1" tyre on a 25mm internal width rim.
** Size SM and up. Tested with a Vittoria Mezcal 29 x 2.35" tyre on a 25mm internal width rim. This is the maximum we have tested. Be warned - mud clearance is extremely limited with such a wide tyre choice.
Light, Strong, Durable
With a carefully selected, and delicately shaped titanium tube set, Big Kev is built to last. We’ve proven this with industry-standard MTB-level testing, even with the lightness of titanium.
The detailing on Big Kev takes Curve bikes to the next level. A custom yoke, with asymmetrical chainstays and dropouts, allows super wide tyre clearance with a road Q-factor. This exquisite yet complex rear-end, tied together with an 85.5mm bottom bracket shell, provides a sturdy platform under load. The dropouts are the first in the Curve range built around the SRAM Universal Derailleur Hanger (UDH).
Adventure Ready
Let’s face it, to tackle the biggest bikepacking adventures with confidence, you need a bigger tyre. A narrow gravel tyre won’t cut it – no one wants to slash a sidewall on day one or walk a bike up a rocky climb due to lack of traction. Big Kev gives you all the benefits of a drop bar, but with the comfort and traction of a gravel-plus tyre.
Whether it’s single-day gravel missions, multi-day flashpacking, or racing the Tour Divide, Big Kev is ready for what you have planned.
More Storage. More Mounts. More Groupset Options
Big Kev is built with a large main triangle compared to other 29er formats to accommodate full-size frame bags for extra storage, even on smaller sizes. With three bidon mounts, rear rack and fender mounts, and 1x groupset options (boost cranks are not required), Big Kev has a variety of riding styles covered.
Our Ride 415 fork has offset adjustability to fine-tune your ride. In addition, the 3 x M5 mounts on each leg allow you to carry Rocket Pooches, extra bottles or fork-specific bags. Rated to carry up to 8 kg on each fork leg, this class-leading fork is amazingly robust.

Customer Reviews
Last ride was a steel rig with 650b wheels. Taller head tube gave me more stack and a bit less reach.. Curve team helped me dial in the right size and slight adjustments on stem length and position. Immediately felt MUCH better. A bit more aggressive position felt great… actually more comfortable. Big Kev handles like a dream. Feels faster, more stable, climbs better, sprints better and when loaded with gear, handles amazingly. After a season of riding, I can’t say enough great things. Best investment and highly recommend this bike if you’re looking for a drop bar adventure bike capable of doing it all. Big Kev keeps up with the fast gravel bros and has enough toughness to handle trails and bikepacking. I do hope Curve improves the flip chip/wheel interface on the fork and upgrades to internal routing on the fork. So very minor though.
Big Kev and I are best friends. This bike is amazing!
Took my Big Kev to do the Roam Scotland Rally, crossing rugged grounds of the Cairngorms nationaal park. Nothing could stop this Ti machine! Crashed 3x but no harm done. Some blood, some mud and a big grin knowing this is not a carbon frame and also has the T-Type transmission without a derailleur hanger. Ride on!
Doing longer rides on rough fire trails, I had a need for a bike that could go for days carrying a bunch of stuff, be more efficient than my MTB, and have a bit more stability than your average gravel bike.
After a lot of research I settled on Big Kev. It was a bit of a commitment step, but no regrets. This thing is a different proposition to my other bikes, it can take on pretty much anything and super fun in undulating trails.
I loved my Big Kev from the start, but it wasn’t until we rode together in some extremely challenging conditions during a bike packing race that I realised how awesome he truly is. Big Kev coped with everything thrown at him - thick sticky mud and rain and the geometry proved so comfortable to ride. The 29ers roll super smoothly, even when I was carrying extra gear for overnighters. I love the dinner plate on the 10-52t cassette, and combined with the traction of the wheels, it gets me up and down almost anything with more confidence and comfort. Being more of a road bike rider, the extra confidence on the gnarly trails makes for a much more relaxed ride which is a big plus. Big Kev you’re the best!
A big shout out to the Curve crew who have been incredibly kind in helping me choose the right bike and size and helping me set up everything. I love how Curve values their community and shows care.
