Pro Bike: Tahnee Seagrave’s Transition TR500

From boxes and bits to complete build...

We’ve been fans of TAHNEE SEAGRAVE since the very early days, we remember her flying around on one of ex-Dirt team rider (and World Champion) Vanessa Quin’s old baby blue Intense bikes. Everyone knew back then that Tahnee was going to be something special. Team FMD (Follow My Dream) was formed and she was off.

Fast forward a chunk of years and we now find Tahnee aged 20, a junior World Champ, a regular on the World Cup podium and a senior World Champs bronze medalist. She has come of age. But there has been a lot of change recently for the young British rider. The whole Seagrave family have now moved back to the UK from their long time home near Morzine in the French Alps, and of course more recently Tahnee and the whole FMD team have signed to Transition Bikes. We look at Tahnee Seagrave’s Transition TR500.

We sent photographer Laurence Crossman-Emms along to Seagrave HQ in deepest darkest Wales to document Tahnee Seagrave’s Transition TR500 downhill bike build with mechanic Matt Allingham (The Bicycle Service), and we fired her some questions too.

Where do you live?


How would you describe your riding style?

I’d say I’m quite composed and relaxed, I’m not very aggressive, but I have an alert posture.

So how different is this to your Devinci that you have been riding for the last few seasons?

Well this bike is more playful. The Devinci has a real low bottom bracket, which is awesome for corners and ploughing through rough stuff, but the Transition TR500 is real poppy and fun. It also feels amazing when putting the power down, it doesn’t drag.



Did you just get on the bike and feel comfortable from the get-go?

Yes, I tested a few different bikes before signing with Transition, but this was the one I instantly felt good on.

Is it a ‘straight out of the box’ frame or are we talking a ‘custom build’ here?

Straight out of the box stock frame.

Tell us about the special stuff you’ve got going on here?

The set–up is pretty much stock that anyone can buy, the main things will be the suspension which has been setup by Fox to suit my style and weight. I’m testing some new compounds from Ergon for the grips and we have been refining an awesome new DH saddle from them as well. I switched over last season to the new CrankBrothers Mallet E pedals, these are marketed as Enduro products but feel great with my smaller feet – we have swapped the axles out for the slightly longer DH versions. Of course there are a few other things that my mechanic Matt does to make the bike feel ‘mine’.

How would you describe this bike’s set–up?


How are you running the head angle?

Approx 63 degrees.

Tell us a bit about your suspension?

On the front I have a Fox Float 40, it’s my first time on an air DH fork and I am so grateful to have done the pre–testing with Fox, as they feel unreal. On the back it’s the DH X2 coil shock. The TR500 is a super progressive frame so the coil shock is best suited and feels amazing.

What about tyres?

Tyres are the same as every season, when you have the best in Schwalbe’s Magic Mary’s – why change? We started running the ProCore system last year too.

What do you feel is the most important part on your bike?

The colour, because it is fast! Ha ha. I think every bike has a geometry that works. The most important part is getting the suspension dialled to feel comfortable on the bike.

Is this bike much different to what you would normally ride?

I literally ride what I’m given! Every bike I’ve had so far has been very different to one another, it just takes time to adapt.

You got any idea of the weight of this bike?

About 36lbs, all stock, no titanium bolts.



No titanium bolts?

No, we are not confident with this material in hi-stress situations, there are other better products available.

Did you go through many parts?

Matt has it easy, I’m the least aggressive rider in the team.

If you could change one thing about the bike what would it be?

If you look at the build, there is not one thing we need or want to change, I can not ask for better sponsors. If a product is not good enough, I can run something else, but in all cases there is no need to change. I’m really lucky with what I’ve got and if I were to buy a bike and choose my own parts, I’d buy this one!
