On the carbon end of the spectrum you have the Jeffsy CF PRO is second in line so to speak. This comes equipped with SRAM Guide RSC stoppers and SRAM Eagle XO1 gearing. Damper wise, a Fox Float elite performance shock holds the rear up taking the 150mm travel that all of these models have to offer, the FOX 34 performance elite 150mm fork upfront is the first point of contact. With the Maxxis rubber, Race Face SIXC cockpit and E-13 TRS wheelset this is a very generously specified bike.

Top of the pile however is the Jeffsy CF PRO Team, a different beast to the others with an extra 10mm of suspension travel to offer through a FOX Float X Factory at the rear and FOX 34 Float Factory up front. The SRAM Eagle has gone and been replaced by SRAM X01 11 speed and an E-13 TRS+ cassette with an impressive 9 tooth bottom gear almost giving the same range as the Eagle. E-13 rubber matched up with the TRSR SL wheel set makes for a light and stiff build. SRAM Guide ultimate stoppers and Renthal bar and stem round it up nicely.

RIDE

The proof is in the pudding they say, so how does the Jeffsy ride? The bike in question was the top end CF PRO team in size XL. In terms of size a six foot tall rider will be good all day on the XL, it was certainly right up my street and, together with the Reverb on full extension for the climbs and slammed down for descents there is a good clearance. If I’m being picky it could well be short in the top tube for the overly tall riders out there.

It’s in the suspension and travel that you begin to see differences between the bikes. The new Jeffsy’s are all running a metric length shock with a 230mm eye to eye. The difference between the other five builds to the top team bike is the stroke length. The lower models have a 60mm stroke and the FOX Float Factory has 65mm giving an extra 10mm shock travel. The main frame design is the same throughout though. The 160mm CF PRO has a 66 degree head angle, it’s lively and nimble feel on track, easy to pedal the few hours up the mountains to get back to the top.
