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

  • Flat-lock stitching
  • Progetto X2 Air Seamless seat pad
  • Weight:172g
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!
