Castelli Free Aero Race 4 Kit Cycling Bib Shorts - SS19
The 2018 Free Aero Race Bibshort is the best-selling Castelli short of all time. So for the 2019 Free Aero bib shorts Castelli made some dramatic changes, not because of pro teams or you were asking for it, but because Castelli rider have been riding in it a ton and thinking constantly about they could make it better. There's a new leg gripper that still features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch. The new fabric allows for better print quality. Updated seams to improve the fit and make the short look even better on the body. Castelli have even re-engineered the bib straps with new fabrics and construction so they stay cooler, lie flatter and are more durable. The revised Free 3 Aero Race Bibshort also receives the updated Progetto X2 Air seamless seat pad featuring the softest surface fabric you've ever felt in a seat pad.
  • Vortex dimpled fabric on legs for aero performance
  • Forza fabric on inner legs with 38% Lycra® content for perfect fit
  • Stripe mesh engineered minimalist bib construction keeps you cool
  • Giro4 leg gripper elastic for better grip distributed over larger area
  • Doppio V construction in front for increased support and comfort
  • Flat-lock stitching
  • Progetto X2 Air Seamless seat pad
  • Weight:172g
RP Can't vouch for the supposed aero gains, but they look good and are very comfortable! Also, Merlin sold them at a great promo price!
Mr Kim I love the material, the pads, the Aero design.
pete d Best shorts I’ve ever ridden in and merlin sells them at a $ way below any of the us retailers. pkg arrived in under a week. 6’3” 205 w 35” waist xl was good snug fit.
Montreal Biker I've been using various iterations of these shorts for 10 years now, these latest versions are superb, long enough in the leg, grippy on the thigh and the Progetto X2 pad is comfortable on 5 hour rides. Not sure if the aero dimples work but they look cool.
Tod Too small, even for Castelli. These are beautiful shorts, and I was excited to try them. But they were markedly too small--couldn't even pull them over my thighs, even though I've been wearing 2XL in Castelli for years. As a reference point, I tend to wear L or XL in other brands, at 6'1" and a muscular 200 pounds. So, if you have larger thighs as I do, consider going up two sizes for this particular Castelli, instead of your normal one.
Kevin Liked the SS18 version so much that I bought another pair in SS19. Aero and comfortable. Like the updated pad color.
Mr Stoodley Great shorts, simply my favourite. These just seem to fit me well with a good length length as well. comfortable well made shorts.
Gabor Very comfortable bib shorts, I just tested it on a 7 hour ride. Be careful with the sizing Castelli's short are smaller.
Mr Murphy I like these bibs a lot. But they are a bit tight. I’m 6’, 175 lbs and they are nicely compressive and snug.
Mr Lee the quality is good.. size is one notch smaller. bought the L and it was more like an M. It is definitely one size smaller than the Velosimo IV.
James first international order and it was perfect!!
alan I have several pairs of these shorts and the sizes are very small fitting. Once you establish yoursizes they are outstanding. I order 2 sizes up from normal. The seat pad is fantastic and I've riden 402 miles in the 24hr tt without any issue whatsoever. Pretty good endorsement I'd say
Pavel Absolutely amazing! The new pad is marvellous. Didn't think they can get any better from the previous version. But it's a significant improvement when it comes to ride comfort. I know many people buy Castelli one size up but I am not one of them. It is challenge to put on but I like the snug fit!
Mr Head Good for use on the road and also the turbo. Usually I am a size small however went for a medium in these and they fit nicely.
Matt Fletcher Ignore Castelli sizing. I’m 170 and 70kgs. Their sizing suggests I’m between a small and medium. Actually I’m between medium and large. The mediums are tight but a better leg length for me. But the shoulder straps don’t have enough stretch to be comfy. It’s a shame as this lets down an excellent pad and otherwise good pair of shorts.
William Very comfortable and the size XL fits very well (for 82 kg & 173cm).
Hatster I have tried five or six brands of shorts and I have found the best by far are CastellI. This is my second and slightly cheaper pair but they don't disappoint. Great fit, real comfort on longer rides - I shall be ordering some more soon. And if it is important to you, very stylish too. Plus rapid delivery, so at this price, a right bloomin' bargain.
Steven Very nice bib. Fits quite small. I am usually an XL in Castelli but maybe 2XL would have been better. By comparison, I am a large in Specialized clothing.
Mr Lynex Fit is slightly on small side, but you might want that for racing. Could be cooler in high 20oC's as previous versions
Ross The latest version of these shorts is better than ever, I do a lot of miles training & racing and for years now they have consistently been the best shorts available. For comfort and function they are worth the full retail price so to get them in the Merlin sale was a real bonus.
Sparky I weigh 70kg, height 172cm. Medium OK but cosy fit. Great gear at a great price and impeccable service from Merlin as always.
chris Superb overall quality and feel. Far better than expected. Very PRO. Pad is as good as I've experienced. Fit is obviously on the small side with Castelli, so go a size up. Would definitely buy again.
Silver Trainer These shorts fit very snug even though I went up a size. This is my first short with compression feature in the legs. My first ride out for a 110k was great. I liked them so much I was ready to buy another pair but they were sold out in my size.
Daniel Love these shorts, great compression and support on long rides. Better than Le Col, Assos, Rapha top line shorts - brilliance and great discount from Merlin👌
Chris Minor improvements over last year’s design. Pad seems a bit more supportive that other progetto pads I’ve tried in the past. I’m also not sure the revised bib is in anyway better than the old style. If you’re tall and slim, they can become quite narrow when stretched. I haven’t noticed any discomfort due to this though.
Ben Went out for a 50 k ride was so comfortable and felt great really happy with castelli bib short.
Mr Campbell Outstanding comfort on my longer runs. I can not see past the X2 padding for comfort. Highly recommend.
SHINJI 身長167㎝、体重66㎏、ウエスト78㎝、尻周り94㎝、太もも58㎝です。サイズチャートで選ぶとMですが、Lのほうがいいかと迷いましたがMを購入。結果的にちょっときつ目でした。十分着られるのですが、太ももあたりは生地が伸びてブラックがスティールブルーに見えてしまいます(笑)。パッドの位置合わせにも結構な力が要りますが、合わせてしまえばズレる心配はありません。が、やはい私の体形ではLサイズが正解だったのかもしれません。しかしながら、縫製などはきちんとしているし、生地の感じはGoodです。パッドはやや厚めの印象ですが、feelingはGoodです。
Montreal Biker Always had good experience with the upper level Castelli gear, these shorts are no exception. The Progetto X2 pad is my 'go to' seat pad - super comfy on multi-hour rides, compression and leg grippers are perfect, straps are comfortable. Hours in the saddle are no problem for these shorts, and a great price at Merlin!
