Released two weeks ago, we've now got one of the brand new, hot off the press Calibre Bossnut mountain bikes in for review. The new 2020 bike gets a new spec and geometry updates, it comes at just £1,100 and we can't wait to ride it!

• Calibre Sentry review
• Calibre Bikes Ladies Bossnut V2 review

 

There are just two models of bike available, that's the men's (or unisex) one and the women's one. Both bikes are pretty similar actually, they come with the same fork and shock, just the ladies bike gets narrower bars and a rather nice grey/teal colourway rather than the striking red of the men's bike so whatever you read from here on in works for both bikes.

Starting with the price, the new Bossnut is just £1,100 with a Go Outdoors discount card. The card costs a fiver which gets you mega discounts in the store,  and with the full price of the bike coming in at £1,500, it's a no brainer - get the card, save a ton of cash, easy. 

For your dollar you get a Rockshox Recon RL fork with 130mm of travel and out at the rear there is a Rock Shox Monarch R shock, giving the bike 130mm of travel. It gets the same linkage driven single pivot as the last iteration of the bike, on which we found worked well last time we tested this bike. 

Stopping comes by way of SRAM Level T brakes and starting uses the new OEM only SRAM groupset, SX Eagle. Yep, 12 speed on a bike that costs just over a grand. This bike gets a 32T chainring with 170mm cranks. The cassette at the rear is an 11-50T with the same gear spacing as NX Eagle. This is going to be many riders first foray into 12 speed and such a wide range cassette and we are pretty sure it will be a selling point for most. 

Elsewhere there are WTB ST i29 27.5" wheels with WTB Vigilante High Grip Comp 2.3" tyre on the front and WTB Trail Boss Comp 2.25" at the rear. There is a 45mm stem and 780mm wide, 30mm wise, 31.8mm bars. 

As we mentioned the travel is 130mm which is the same as last year's bike, the frame is new however with the geometry tweaked for 2020. The bike is more stretched out this year with the medium bike (for example's sake) getting a longer reach by 13mm, up to 442mm. All bikes have a slacker head angle by 2 degrees, now 66 degrees and a steeper effective seat angle, now at 74.5 degrees. Rear chainstays stay the same length at 436mm but the bottom bracket is lower and the seat tube lengths are shorter across the board to allow for longer dropper posts to be inserted. The price doesn't include a dropper post but with the savings made we'll guess most buyers will put one at the top of their upgrade list from the very start. There is internal cable routing ready for a dropper post, the cable will be routed down the underside of the downtube, under the bottom bracket and up into the seat tube at the rear. 

We reviewed the old Bossnut V2 last year and loved it, giving it 5 stars, we also really liked Calibre's new (ish) long travel 29er, the Sentry, dishing out five gold stars to that one too. Rachael will be getting on this bike over the next few weeks, check back soon for a review and see how she got on.
