Below are answers for our most frequently asked questions. If your question isn’t answered here, please contact us.
Q. Do you offer international shipping?
A. Yes we do; the basket total will display the shipping cost – click on ‘Calculate Shipping’ to check your details are correct. The shipping cost will also update automatically when you enter your delivery address at the checkout. If you have any problems, please contact us and we’ll set it right.
A. Our standard finish is our signature dark clear lacquer, which features integrated graphics (no stickers!) and shows the true finish of the frame; welding heat marks, variations in the surface finish of the tubes, material differences, etc. This unique finish leaves nothing to the imagination, and is a testament to our dedication to building the world’s best frames.
Here are a few examples…
If you’d rather cover your frame in colour we can offer a range of standard powder coat colours. We also have access to some special candy or metallic colours, so if you have something special in mind please contact us.
A. As a general guideline BTR frames are intended for the rider heights in the following table. We can design and build custom sizes too! Contact us and we’ll be more than happy to discuss your needs!
|Frame Size||Min. Rider Height||Max. Rider Height|
|Custom||-||156cm (5' 1.5")|
|XX Small||152cm (5' 0")||162cm (5' 4")|
|Extra Small||158cm (5' 2")||168cm (5' 6")|
|Small||164cm (5' 4.5")||174cm (5' 8.5")|
|Medium||170cm (5' 7")||180cm (5' 11")|
|Large||176cm (5' 9.5")||186cm (6' 1")|
|Extra Large||182cm (5' 11.5")||192cm (6' 3.5")|
|XX Large||188cm (6' 2")||198cm (6' 6")|
|Custom||194cm (6' 4.5")||-|
Q. What size clothing should I buy?
A. BTR clothing has the following measurements:
A. Because we build all frames to order, there is some delay between you ordering a frame and then receiving it. Exactly how long this lead time is depends on how busy we are! Lead time is normally 8 weeks for a hardtail, or 12 weeks for a full-suspension frame. Our lead time is never less than 4 weeks, and rarely over 16.
Shipping is pretty speedy, with most UK orders delivered within 2 working days, and international orders in around a week. We supply tracking details whenever possible, so you can check where your frame is along the way.
T-shirts, hoodies, Trail Tools and spare parts are generally held in stock, so they are dispatched within a few working days.
Q. What type of headset fits a BTR?
A. From 2013 onwards, all BTR frames feature a straight 44mm head tube. All frames are only compatible with headsets with an external lower cup. So the S.H.I.S. code is ZS44/28.6/H8 | EC44/40/H12 for a headset that accepts a tapered steerer. The S.H.I.S. code for a straight 1 1/8″ steerer is ZS44/28.6/H8 | EC44/30/H12.
Belters made before 2013 are only compatible with IS41/28.6/H9 | IS41/30/H1 headsets.
A. It’s an extra line of text which we can add to the head badge on your frame, separate from the model, serial and date. It’s limited to a maximum of 11 characters A-Z, 0-9. You could add your name, or your partner’s name, or your favourite film…it’s up to you!
Here are a few examples…
A. It’s a seat clamp which is welded to the seat tube. They’re small, lightweight, neat, and secure – you need a 5mm Allen key to loosen/tighten them.
Here are a few examples…
A. If you want to run any sort of chain retention device, you really do need a chain device mount. If you’re happy to rely on a narrow/wide chainring or are using a front derailleur, then you don’t need one. All of our chain device mounts are ISCG05, which is the current, slightly larger 3-bolt standard. ISCG-old chain devices look very similar, but aren’t compatible!
No ISCG05 mount:
With ISCG05 mount:
A. They’re stainless steel, and they’re sealed! The bolt holes don’t go all the way through, so even without bolts or a cage in place there’s no way for water to get into the frame. Being stainless steel, rust can’t even start in the boss itself either!
Q. How much assembly is needed on a complete bike?
A. We do need to ship the bike to you in a few pieces, so assembly is required. We’ll do the awkward bits like pressing in the headset, cutting the fork steerer and installing the star nut, installing and seating the tyres, and installing the cassette. You’ll need to finish the assembly, which should be possible with little more than a decent multitool. We strongly recommend having a qualified bicycle mechanic at least check the bike for you, if not assembling it completely.
Q. Can I change any of the components on a complete bike?
A. Sure! We can switch a few parts or even put together a completely custom build for you – get in touch to discuss your needs!
A. Steel frames only need preventative maintenance to halt the progress of rust. We specifically build our frames to minimise the ingress of water, but we still recommend you periodically check for water, and spray a water displacer such as GT85 or WD40 into the seat tube, BB and head tube of your frame. The following table shows our recommended intervals:
|FRAME AREA||WET CONDITIONS||DRY CONDITIONS|
|SEAT TUBE||2 Weeks / 100 Miles||1 Month / 200 Miles|
|BOTTOM BRACKET||2 Months / 400 Miles||6 Months / 1000 Miles|
|HEAD TUBE||3 Months / 600 Miles||6 Months / 1200 Miles|
Please note that this is a guideline only; it is your responsibility to ensure that your frame is kept clean and dry!
Q. Where can I see BTR products in the flesh?
A. If you want to have a look or a feel before you buy, get in touch; we have ride days and attend events and races around the UK.
Q. Are there any BTR distributors?
A. Yes; Yuris is an agent covering Japan.
Q. Can you tweak the geometry of the frame for me?
A. Sure! We can actually change the geometry of our frames quite significantly in most cases. This will incur a surcharge which will vary depending on the changes you want. Contact us and we’ll be more than happy to discuss your needs!
Q. Which geometry customisations are available on a full suspension BTR?
A. We can’t offer all of the custom geometry options that we currently offer on our hardtails because of the rear suspension; we can do custom reach, head angle and seat tube length, but customising the BB height, seat angle and chain stay length are much more problematic. Contact us and we’ll be more than happy to discuss your needs!
Q. Do BTR frames have adjustable geometry?
A. No. We don’t like the extra complication, expense and general faff of frame adjustments, so we don’t include them. Time spent adjusting your bike is time not spent riding it. What we have done is paid close attention to the geometry, so that the bike does what it should as well as it possibly can.
Q. What does linear progressive suspension do?
A. Progression means that the suspension mechanism increases the stiffness (how much force is required to move the suspension a certain amount) of the suspension the further you go into its travel, rather than just relying on the spring rate. ‘Linear progressive’ means that this increase in stiffness is delivered in a steady manner- this is one of the key ingredients to predictable suspension. Having the right amount of progression, delivered in the right manner, allows you to ride hard without excessive, sluggish damping, and without bottoming out the suspension harshly.
Q. What is the base setting for the Cane Creek DBair on a pre-2017 Pinner?
1x large air volume spacer
1.25 turns HSC from fully open (4 total)
14 clicks LSC from fully open (21 total)
2.5 turns HSR from fully open (4 total)
16 clicks LSR from fully open (21 total)
Q. Whats the recommended sag on a pre-2017 Pinner?
A. 20% at the rear wheel…thats about 10mm at the shock. Remember to set the sag for a standing position! For a rider weighing about 75kg, that will be around 150psi in the DBair.
Q. What kind of riding is the Pinner for?
A. We are downhillers at heart, but we wanted a bike that we could ride all day, up and down. The result is the Pinner with it’s enduro style geometry, trail bike travel, and DH bike strength.
Q. Can I fit a front mech to the Pinner?
A. No, sorry. There simply isn’t the space for one between the main pivot and crank/chainring. But then, with so many single-ring setups delivering huge gear ratio ranges nowadays, why bother? You can have ISCG05 mounts for a chain device too.
A. It’s because of how a hardtail behaves; there is no suspension movement at the rear, so as you use travel at the front the whole frame effectively pivots around the rear axle, causing the geometry to change. The more suspension travel you have at the front, the more the geometry can change. Running rigid forks would give no geometry change but obviously a harsh ride. Long travel forks would give the best ride, but they will allow large geometry changes which make the bike feel unpredictable. So we have chosen what we believe is the best balance; enough travel to give a supple ride but not so much as to cause the bike to feel unpredictable. It might seem like our specifications are short compared with today’s full suspension bikes, but rest assured that we’ve selected the correct travel for our frames.
Q. What can I do if the only forks I want to use are longer travel than the BTR specifications?
A. We will normally reduce fork travel free of charge with a frame order, so long as we have your forks before your frame is dispatched. Often there are specific spacers or parts available from the fork manufacturer to reduce the fork travel, but if these parts aren’t available we can normally produce parts instead. Sometimes travel adjustments aren’t possible though, so please contact us for more information.
Q. What’s the deal with 44mm headtubes?
A. 44mm head tubes have been around for quite a while- they’re commonly called Zero Stack (ZS) or Semi-Integrated (SI). Its only since around 2013 that headset manufacturers have taken full advantage of their versatility, offering external cups to accommodate straight 1 1/8″, tapered, and straight 1.5″ steerers. On a straight 1 1/8″ steerer you can even run an Angleset. Its become particularly popular on steel framed bikes because of its versatility, and it fits the frame tubes much better than a 1.5″ or larger head tube does.
Q. What happened to the X gussets?
A. We were always aware that the X gussets were pretty weird aesthetically, so we’ve been on the hunt for a cleaner solution for a while. Our new tubular gussets are every bit as effective as the X gussets, and a lot more sleek. They aren’t just round tubes either- they’re ovalised at the front end to distribute the stress better.
Q. Do you do any FEA testing?
A. Yes, days of it for each frame. We run multiple scenarios to challenge the frame in every way we can foresee.
Q. Who rides BTR prototypes?
A. They’re mostly been ridden by the guys who own them; people like you! We also have our fair share of time on them too, so that we can make sure we’re happy with them. Most also get some time under an elite racer, just to double check they can take the strain that comes with serious pace.
Q. What if I break a BTR, will I get a new one?
A. We don’t have a formal warranty, but we stand by our products 100%; We’re not out to mess anyone around – if its our fault, we’ll make it right. In the event of a failure we’ll carefully consider the options for how we go about repairing or replacing your frame.
Q. What about CE tests?
A. We haven’t seen the need for them, and here’s why: Our FEA simulations exceed the CE tests, so once that’s done we’re confident that our frames would pass. We then go on to test our bikes with real riders – not just us, normal riders and national-level racers too – which concretes our belief that our frames are fit for purpose.
Q. Can I visit the BTR workshop?
A. Sure, but only by appointment! If you like, you can even help with parts of the build process of your frame; tube notching, weld preparation, etc. Contact us to arrange a visit.
Q. How can I get BTR sponsorship?
A. We have a very limited budget, so if you’d like to be sponsored by BTR you’ll really have to inspire us to take you on board. We are most interested in sponsoring riders who we believe reflect our philosophy on bikes, riding and life in general, rather than those who are fast or at the top of their game. A sponsored rider’s main job is to promote BTR, and this means regularly generating unique, engaging and inspiring content for social media, our website, and beyond; riding and racing has only very limited impact, unless it’s at the sharp end of international competition. It’s a big commitment for us, which needs a big commitment from you too.
N.B. Emailing or messaging us simply asking if we want to sponsor you will get you nowhere; we won’t even bother to respond. If you really want to be a part of the BTR team, you need to tell us about yourself, your riding, why you want to be on the team, and most importantly how you can help promote BTR, and any further information that you think we’d like to hear.
Q. Can I split the payments for my frame/bike?
A. We can take payment for frames and bikes in installments if needed; 70% in advance, and the remaining 30% plus shipping on completion. Custom builds will require a design phase, which would be the first installment to pay in that case; this amount is non-refundable once the design work is completed.
