I might be able to help?
I have a spare fork sat in the loft. It is from a GT Grade carbon
1 1/8" to 1 1/4" tapered steerer measures 273mm. 15mm through axle (included) and has mounts for mudguards and loads of clearance. The pictures below show the same fork on my current bike with a 35mm Vittoria Randonneur and no trouble fitting my Schwalbe 35mm knobbly CX tyres.
This can be yours for £40 including the thru axle and postage.
****WARNING**** I cannot sell you these (this?) forks without giving you some additional information. They are off my last bike which was written off after I was hit side-on by a car turning across/into me at a junction. The impact cracked the frame in several places and point of impact was the down tube just in front of the chainset.
I have no recollection of the accident after seeing the car bumper inches from my leg. I must have hit the road pretty hard because I suffered a broken neck and fractured skull!. The bike somehow seemed to come out of it all otherwise unscathed. Apart from the impact damage to the frame there was not a single scuff, scratch or mark to any other part of the bike that could be attributed to the bike being flung down the road at 20+ MPH. The saddle, brake levers, bar tape and pedals are untouched. It is almost as if I braked to a controlled stop before carefully placing my bike on the ground then throwing myself violently to the floor (I know this didn't happen)!
I have carefully inspected them and I am confident they are free from damage, so confident that I am prepared to sell them, if I wasn't they would have been sawn in two and tossed in the bin to stop anyone from ever using them. They are kept as a spare for my current bike or 'just in case' for any potential future builds. Even though I am sure they are good I don't think it would be fair to sell them without disclosing the above for your consideration.
PM me if you are interested or have any questions.
