The all purpose, tough as nails 29er/27.5+ adventure frame; designed to take you well off the beaten track and beyond. Whether you’re running a lightweight bikepacking setup, front and rear panniers for a fully loaded ’round-the-world’ tour or just stripped back to thrash some forest trails the Big Bro can handle it.

New for 2025: With the following updates the Big Bro is now an even more capable adventure frame - heat treated 4130 chromoly main triangle, new configuration sliding dropouts for a stronger and more reliable rear end, UDH full mount compatible rear mech hanger, top tube bag mounts and additional front rack mounts.

The frame is now constructed out of extra tough 'heat treated' 4130 double butted cro-mo tubing and comes with a 100mm suspension corrected fork, both with corrosion resistant ED coating applied. The Big Bro features Boost spacing which means there's clearance for big 27.5 x 3" tyres or 29 x 2.6" tyres if you'd prefer to go with a 29er setup. It features stealth dropper routing, multiple rack and bag mounts, a bottle mount on the seat tube and triple mounts on and under the down tube for extra bottles and storage. The Big Bro fork also features triple mounts to fit further bottle cages or Anything Cages.

The rear triangle features S-bend chainstays with replaceable alloy thru axle sliding dropouts for geared or singlespeed setups. These have been re-designed for 2025 to now feature a rail system for extra strength and reliability.

Brother Cycles now offer a Rohloff specific dropout set which makes the Big Bro compatible with the Rohloff 135mm Speedhub with OEM axle plate. Ask us for details.

Like all Brother products the Big Bro has been rigorously tested out in the real world – they took prototypes across the South Downs, through Snowdonia National Park and up to the Scottish Highlands. The Big Bro has since completed many of the world’s toughest bikepacking endurance races – including the 4,418km Tour Divide from Canada to Mexico and the 1,710km Silk Road Mountain Race in Kyrgyzstan.

This one is a keeper…
Size: 36D, Color: Nude
Bra shopping is truly one of my least favorite things to do, and it is always so frustrating to me. Online bra shopping tends to be even worse, so I had little hope for this bra but took a chance anyway. I was pleasantly surprised by how much I liked it! A true test for me is whether or not I notice I’m wearing it. I’ve worn it off and on for several days and I totally forget about it. Having nurses two babies and approaching my 40s, my girls need a lot of support and this bra delivered. I thankfully discovered years ago that if you have deflated mom boobs, an unlined cup is the best way to take what you have and give it shape. This one does just that. I have very mixed feelings on the lace though. On the one hand, it is sexy and feminine and I don’t find that in bras very much anymore (at least not ones that provide the kind of lift and support that I require). However, the lace is very noticeable through a shirt. I really can only wear this bra with a thick top or sweater. Otherwise, it’s just too noticeable and I’m not comfortable with that. Wearing a cami underneath a top helps slightly though. Overall, I’m glad I have this bra and I’ll be ordering another color. It feels well made, the material is nice, and it gives my bust a shapely (and youthful 😭) appearance. I wore it all day in 90+ heat at Magic Kingdom and it didn’t bother me at all, so it definitely qualifies as lightweight and comfortable in my book. I took a stab at a size and the 36D feels right. I *maybe* could have gotten a 34 but the 36 doesn’t feel loose on the tightest loops. On occasion, depending on the brand, I can be either a D or DD. I think this is worth trying and looks more expensive than it really is!

Gorgeous Bra, But My Chest Declined the Opportunity
Size: 40C, Color: Black, Size: 40C, Color: Black
This bra is genuinely beautiful and very well made. The fabric, stitching, and overall construction felt much more expensive than I expected. Unfortunately, my body once again reminded me that I am apparently not built according to standard human engineering specs. Every few years I convince myself, “Surely this time I am a normal-sized woman who can wear regular bras.” Then I order one designed for actual flesh-bearing individuals and reality humbles me immediately. The cups stood there optimistically waiting to be filled while my chest contributed little to the project. The straps also kept sliding off my narrow shoulders like they were trying to escape the situation entirely. None of this is the bra’s fault. The fabric is soft, silky, and looks like money. It's just as pretty as the photos. The straps appear as though they could support a lot for a long time. The bra did its job. My body simply refused to participate. If you have average proportions and shoulders that can support standard straps, this is probably a fantastic purchase. I, however, must return to my specialized tiny-person undergarments and accept my fate.

I really like this bra, but...
The bra fir great and I wish I could keep it. The big downfall is the lace and the middle seam. Both show thruogh any shirt material so you can't ear it under anything without the bra showing through as bumpy. I'm returing it for that reason along.
